1. Introduction
The AFS-16-1 is a versatile switching system, designed for applications that require
routing of analog or digital signals between a common RJ45 jack and “A” and “B
RJ45 jacks. The AFS-16-1 is ideal for switching RS232, RS422/485, Ethernet/UTP or
telephone lines.
The system consists of a Card Rack, one Power Supply Module, one Control Module,
and up to 16 Circuit Modules. Each Circuit Module is capable of switching all 8 pins of
the Common RJ45 jack between Jack “A” or Jack “B”. Each card can be switched by
alarm, manually, or by command.
The AFS-16-1 includes an assortment of alarm features, which allow the unit to monitor
temperature, power interruptions, and invalid access attempts and then notify you
via Email, text message, Syslog message or SNMP trap when critical conditions are
detected. The AFS can also monitor device response to ping commands and then
switch A/B paths and provide notification when devices fail to respond.
Security and Co-Location Features:
Secure Shell (SSHv2) encryption and address-specific IP security masks help to prevent
unauthorized access to command and configuration functions.
The AFS-16-1 also provides four different levels of security for user accounts:
Administrator, SuperUser, User and ViewOnly. The Administrator level provides
complete access to all A/B switching functions, status displays and configuration
menus. The SuperUser level allows control of A/B switching, but does not allow access
to configuration functions. The User level allows access to only a select group of
Administrator-defined A/B circuits. The ViewOnly level allows you to check unit status,
but does not allow A/B switching or access to configuration menus.
The AFS-16-1 includes full Radius, LDAP and TACACS capability, DHCP and an invalid
access lockout feature. An Audit Log records all user access, login and logout times
and command actions, and an Alarm Log records user-defined alarm events.

Introduction
Environmental Monitoring and Management:
The AFS-16 can constantly monitor temperature levels, ping response and other factors.
If the AFS-16 detects that user defined thresholds for these values have been exceeded,
the unit can promptly notify you via email, text message, SNMP trap, or Syslog
message. The AFS-16 also records temperature readings to a convenient log file.
The AFS-16 can also notify you when excessive invalid access attempts are detected,
and can automatically lock ports when it determines that an unauthorized user may be
attempting to gain access by "hammering" the unit with random passwords.
WTI Management Utility
The AFS-16 includes the WTI Management Utility, which allows you to manage multiple
WTI units via a single menu. For more information on the Management Utility, please

In addition, the AFS-16 also offers three different methods for accessing command
mode; via network, via modem, or via local console. The Web Browser interface is only
available via TCP/IP network, and the Text Interface is available via TCP/IP network (SSH
or Telnet), modem or local PC.
5.1.1. The Text Interface
The Text Interface (also known as the "Command Line Interface" or "CLI") consists of a
series of simple ASCII text menus, which allow you to set options and define parameters
by entering the number for the desired option using your keyboard, and then typing in
the value for that option.
Since the Web Browser Interface and Telnet accessibility are both disabled in the
default state, you will need to use the Text Interface to contact the unit via Local PC or
SSH connection when setting up the unit for the first time. After you have accessed
command mode using the Text Interface, you can then enable Web Access and Telnet
Access, if desired, in order to allow future communication with the unit via Web Browser
or Telnet. You will not be able to contact the unit via Web Browser or Telnet until you
have enabled those options.
Once Telnet Access is enabled, you will then be able to use the Text Interface to
communicate with the AFS-16 via local PC, Telnet or SSH connection. You can also
use the Text Interface to access command mode via an external modem installed at the
RS232 Port on the AFS-16 Control Module.
In order to use the Text Interface, your installation must include:
• Access via Network: The AFS-16 must be connected to your TCP/IP Network, and
your PC must include a communications program (such as HyperTerminal.)
• Access via Modem: An external modem must be installed at the Control Module's
RS232 Port and the RS232 Port must be configured for Modem Mode as described
in Section 5.8. A phone line must be connected to the external modem. In
addition, your PC must include a communications program.
• Access via Local PC: Your PC must be connected to the RS232 Port on the
AFS-16 Control Module. The RS232 Port must be configured for Normal Mode, and
your PC must include a communications program.

Basic Configuration
To access command mode via the Text Interface, proceed as follows:
Note: When communicating with the unit for the first time, you will not be able
to contact the unit via Telnet until you have accessed command mode via Local
PC or SSH Client and used the Network Parameters Menu to enable Telnet as
described in Section 5.3.
1. Contact the AFS-16 Unit:
a) Via Local PC: Start your communications program and press [Enter]. Wait
for the connect message, then proceed to Step 2.
b) Via Network: The AFS-16 includes a default IP address (192.168.168.168) and
a default subnet mask (255.255.255.0.) This allows you to contact the unit from
any network node on the same subnet, without first assigning an IP Address to
the unit. For more information, please refer to Section 5.9.
i.
Via SSH Client: Start your SSH client, and enter the AFS-16’s IP Address.
Invoke the connect command, wait for the connect message, then
proceed to Step 2.
ii. Via Telnet: Start your Telnet Client, and then Telnet to the AFS-16’s IP
Address. Wait for the connect message, then proceed to Step 2.
c) Via Modem: Use your communications program to dial the number for the
phone line that you have connected to the AFS-16's RS232 Serial Port.
2. Login / Password Prompt: A message will be displayed, which prompts you to
enter a username (login name) and password. The default username is "super" (all
lower case, no quotes), and the default password is also "super".
3. If a valid username and password are entered, the AFS-16 will display the Circuit
Status Screen.
5.1.2. The Web Browser Interface
The Web Browser Interface consists of a series of web forms, which can be used to
select configuration parameters and perform switching operations, by clicking on the
appropriate buttons and/or entering text into designated fields.
Note: In order to use the Web Browser Interface, Web Access must first
be enabled via the Text Interface Network Parameters Menu as described in
Section 5.9, the AFS-16 must be connected to a TCP/IP network, and your PC
must be equipped with a JavaScript enabled web browser.
1. Start your JavaScript enabled Web Browser, key the AFS-16’s IP address
(default = 192.168.168.168) into the web browser’s address bar, and press [Enter].
2. Username / Password Prompt: A message box will prompt you to enter your
username and password. The default username is "super" (all lower case, no

Basic Configuration
5.1.3. Access Via PDA
In addition to the Web Browser Interface and Text Interface, the AFS-16 command mode
can also be accessed by PDA devices. Note however, that due to nature of most PDAs,
only a limited selection of AFS-16 operating and status display functions are available to
users who communicate with the unit via PDA.
When the AFS-16 is operated via a PDA, only the following functions are available:
• Product Status Screen (Unit Info) (Section 8.1)
• Circuit Status Screen (Section 8.3)
• Circuit Group Status Screen (Section 8.4)
• Circuit Control Screen (Section 9.1.1)
• Circuit Group Control Screen (Section 9.1.2)
These screens will allow PDA users to review Circuit Status and Circuit Group Status,
invoke A/B switching and display the Site I.D. and firmware version. Note however, that
PDA users are not allowed to change or review AFS-16 configuration parameters.
To configure the AFS-16 for access via PDA, first consult your IT department for
appropriate settings. Access the AFS-16 command mode via the Text Interface or Web
Browser interface as described in this section, then configure the AFS-16's Network Port
accordingly, as described in Section 5.9.
In most cases, this configuration will be adequate to allow communication with most
®
PDAs. Note however, that if you wish to use a BlackBerry to contact the AFS-16,
you must first make certain to configure the BlackBerry to support HTML tables, as
described below:
1. Power on the BlackBerry, and then click on the BlackBerry Internet Browser Icon.
2. Press the Menu button, and then choose "Options."

Basic Configuration
5.3.2. The Invalid Access Lockout Feature
When properly configured and enabled, the Invalid Access Lockout feature will watch
all login attempts made at the Network Port and RS232 Port. If either port exceeds the
selected number of invalid attempts, then that port will be automatically disabled for a
user-defined length of time (Lockout Duration.) The Invalid Access Lockout feature uses
two separate counters to track invalid access attempts:
• Serial Port Counter: Counts invalid access attempts at the Serial Port. If the
number of invalid attempts at the port exceeds the user-defined Lockout Attempts
value, then the port will be locked.
• Telnet, SSH and Web Browser Counter: Counts all invalid attempts to access
command mode via Telnet, SSH or Web Browser interface. If the number of
cumulative invalid attempts exceeds the user-defined Lockout Attempts value, then
the Network Port will be locked.
Note: In the Web Browser Interface, the Invalid Access Lockout item does
not appear in the System Parameters menu, and is instead accessed via the
General Parameters fly-out menu as described below.
Note that when an Invalid Access Lockout occurs, you can either wait for the Lockout
Duration period to elapse (after which, the AFS-16 will automatically reactivate the port),
or you can issue the /UL command (type /ULand press [Enter]) via the Text Interface to
instantly unlock all of the AFS-16's logical network ports.
Notes:
• When the Invalid Access Lockout Alarm has been enabled as described
in Section 7.4, the AFS-16 can also provide notification via email, Syslog
Message, and/or SNMP trap whenever an Invalid Access Lockout occurs.
• Invalid Access Lockout parameters, defined via the System Parameters
menu, will apply to both the Serial Port and the Network Port.
• When a Serial Port is locked, an external modem connected to that port will
not answer.
• If either the RS232 Port or Network Port are locked, the other port will remain
unlocked, unless the Invalid Access Lockout feature has also been triggered
at that port.
• If any one of the AFS-16’s logical network ports is locked, all other network
connections to the unit will also be locked.
• All invalid access attempts at the AFS-16 Network Port are cumulative (the
count for invalid access attempts is determined by the total number of
all invalid attempts at all 16 logical network ports.) If a valid login name/
password is entered at any of the logical network ports, then the count for all
AFS-16 logical network ports will be restarted.
• If the Network Port has been locked by the Invalid Access Lockout feature, it
will still respond to the ping command (providing that the ping command has
not been disabled at the Network Port.)

Basic Configuration
5.3.5.1. Automated Mode
The Automated Mode allows the AFS-16 to execute A/B switching commands, without
displaying menus or generating response messages. Automated Mode is designed to
allow the AFS-16 to be controlled by a device which can generate commands to control
power switching functions without human intervention.
When Automated Mode is enabled, A/B switching commands are executed without a
“Sure?” confirmation prompt and without command response messages; the only reply
to these commands is the “AFS>” prompt, which is re-displayed when each command
is completed.
Note that although Automated Mode can be enabled using either the Web Browser
Interface or Text Interface, the Automated Mode is designed primarily for users who wish
to send ASCII commands to the AFS-16 without operator intervention, and therefore
does not specifically apply to the Web Browser Interface. When Automated Mode is
enabled, the Web Browser Interface can still be used to invoke switching commands.
Notes:
• When the Automated Mode is enabled, password prompts will not be
displayed at login, and you will be able to access Administrator Level
command functions (including the configuration menus) and control circuits
without entering a password.
• If you need to enable the Automated Mode, but want to restrict network
access to configuration menus, it is strongly recommended to enable and
configure the IP Security Function as described in Section 5.9.3.
To enable/disable the Automated Mode, go to the System Parameters menu (see
Section 5.3,) and then set the “Automated Mode” option to “On”. When Automated
Mode is enabled, AFS-16 functions will change as follows:
1. All Password Security Suppressed: When a user attempts to access command
mode, the password prompt will not be displayed at either the Console Port
or Network Port. Unless specifically restricted by the IP Security Function, all
users will be allowed to access both switching and configuration functions, and
all commands will be immediately accepted without the requirement to enter a
password.
2. Status Screen Suppressed: The Circuit Status Screen will not be automatically
displayed after commands are successfully executed. Note however, that the /S
command can still be invoked to display the Circuit Status Screen as needed.
3. “Sure?” Prompt Suppressed: All commands are executed without prompting for
user confirmation.
4. Error Messages Suppressed: Most error messages will be suppressed. Note
however, that an error message will still be generated if commands are invoked
using invalid formats or arguments.
All other status display and configuration commands will still function as normal.

Basic Configuration
5.4. User Accounts
Each time you attempt to access command mode, you will be prompted to enter a
username and password. The username/password entered at login determine which
circuit(s) you will be allowed to control and what type of commands you will be allowed
to invoke. Each username / password combination is defined within a "user account."
The AFS-16 allows up to 128 user accounts; each account includes a username,
password, command access level, circuit access rights, service access rights and an
optional callback number.
5.4.1. Command Access Levels
In order to restrict access to important command functions, the AFS-16 allows you to
set the command access level for each account. The AFS-16 offers four access levels:
Administrator, SuperUser, User and View Only. Command privileges for each account
are set using the "Access Level" parameter in the Add User or Modify User menus.
Each access level grants permission to use a different selection of commands; lower
access levels are restricted from invoking configuration commands, while Administrators
are granted access to all commands. The four access levels are listed below:
• Administrator: Administrators are allowed to invoke all configuration and operation
commands, can view all status screens, and can always direct A/B switching
commands to all AFS-16 Circuit Modules.
• SuperUser: SuperUsers are allowed to invoke A/B switching commands and view
all status screens. SuperUsers can view configuration menus, but are not allowed
to change configuration parameters. SuperUsers are granted access to all AFS-16
Circuit Modules.
• User: Users are allowed to A/B switching commands and view all status screens,
but can only apply commands to the AFS-16 Circuit Modules that they have
been specifically granted access to. In addition, Users are not allowed to view
configuration menus or change configuration parameters.
• ViewOnly: Accounts with ViewOnly access, are allowed to view Status Menus
(with restrictions,) but are not allowed to invoke A/B switching commands, and
cannot view configurations menus or change configuration parameters. ViewOnly
accounts can display Status screens, but can only view the status of the AFS-16
Circuit Modules that are specifically allowed by the account.
Section 17.2 summarizes command access for all four access levels.
In the default state, the AFS-16 includes one predefined account that provides access
to Administrator commands and allows to control of all of the AFS-16's Circuit Modules.
The default username for this account is "super" (lowercase, no quotation marks), and
the password for the account is also "super".
Notes:
• In order to ensure security, it is recommended that when initially setting up
the unit, a new user account with Administrator access should be created,
and the "super" account should then be deleted.
• If the AFS-16 is reset to default parameters, all user accounts will be cleared,
and the default "super" account will be restored.

5.4.2. Granting Circuit Module Access
Each account can be granted access to a different selection of Circuit Modules. Note
also, that several accounts can be allowed access to the Circuit Module. When
accounts are created, the Circuit Access parameter in the Add User or Modify User
menu can be used to grant or deny access to each Circuit Module by that account.
In addition, each command access level is also used to restricts the Circuit Modules that
the account will be allowed to access:
• Administrator: Accounts with Administrator access are always allowed to control
all Circuit Modules. Circuit Module access cannot be disabled for Administrator
level accounts.
• SuperUser: SuperUser accounts allow access to all Circuit Modules. Circuit
Module access cannot be disabled for SuperUser level accounts.
• User: Accounts with User level access are only allowed to access the Circuit
Modules that have been specifically permitted via the "Circuit Access" parameter in
the Add User and Modify User menus.
• ViewOnly: Accounts with ViewOnly access are not allowed to invoke A/B switching
commands. ViewOnly accounts can display the status of Circuit Modules, but are
limited to the Circuit Modules specified by the account.

information, please refer to Section 11. (Default = undefined.)
• Ping Access: Enables/Disables response to the ping command. When Disabled,
the AFS-16 will not respond to Ping commands. Note that disabling Ping Access at
the Network Port will not effect the operation of the Ping-No-Access Alarm.
(Default = On.)
• Outbound Access: Enables/Disables the ability to create outbound Telnet and/
or SSH connections via the AFS-16 Network Port. When enabled, users who
are connected to the AFS-16 command mode via the RS232 Serial Port will be
able to connect to the Network Port, and then invoke the /TELNET and/or /SSH
commands to create an outbound connection. For example, to create an outbound
Telnet connection, first make certain that this option is enabled for both the RS232
Serial Port and the password/account, then access command mode via the Text
Interface at the RS232 Port. At the AFS> prompt, invoke the /TELNET command as
described in Section 10.3. (Default = Off.)

Basic Configuration
5.9.3. IP Security
The IP Security feature allows the AFS-16 to restrict unauthorized IP addresses from
establishing inbound Telnet connections to the unit. This allows you to grant Telnet
access to only a specific group of IP addresses, or block a particular IP address
completely. In the default state, the AFS-16 accepts incoming IP connections from all
hosts.
In the Text Interface, IP Security parameters are defined via item 5 in the Network
Configuration menu (Figure 5.9.) In the Web Browser Interface, these parameters are
found by clicking the "IP Security" link on the left hand side of the screen. In the default
state, IP Security is disabled.
The IP Security Function employs a TCP Wrapper program which allows the use of
standard, Linux operators, wild cards and net/mask pairs to create a host based access
control list.
The IP Security configuration menus include "hosts.allow" and "hosts.deny" client lists.
Basically, when setting up IP Security, you must enter IP addresses for hosts that you
wish to allow in the Allow list, and addresses for hosts that you wish to deny in the Deny
list. Since Linux operators, wild cards and net/mask pairs are allowed, these lists can
indicate specific addresses, or a range of addresses to be allowed or denied.
When the IP Security feature is properly enabled, and a client attempts to connect, the
AFS-16 will perform the following checks:
1. If the client’s IP address is found in the "hosts.allow" list, the client will be granted
immediate access. Once an IP address is found in the Allow list, the AFS-16 will not
check the Deny list, and will assume you wish to allow that address to connect.
2. If the client’s IP address is not found in the Allow list, the AFS-16 will then proceed
to check the Deny list.
3. If the client’s IP Address is found in the Deny list, the client will not be allowed to
connect.
4. If the client’s IP Address is not found in the Deny list, the client will be allowed to
connect, even if the address was not found in the Allow list.
Notes:
• If the AFS-16 finds an IP Address in the Allow list, it will not check the Deny
list, and will allow the client to connect.
• If both the Allow and Deny lists are left blank, then the IP Security feature will
be disabled, and all IP Addresses will be allowed to connect (providing that
the proper password and/or SSH key is supplied.)
• When the Allow and Deny lists are defined, the user is only allowed to specify
the Client List; the Daemon List and Shell Command cannot be defined.

Basic Configuration
5.9.3.1. Adding IP Addresses to the Allow and Deny Lists
To add an IP Address to the Allow or Deny list, and begin configuring the IP Security
feature, proceed as follows.
Notes:
• Both the Allow and Deny list can include Linux operators, wild cards, and
net/mask pairs.
• In some cases, it is not necessary to enter all four "digits" of the IP Address.
For example, if you wish to allow access to all IP addresses that begin with
"192," then you would only need to enter "192."
• The IP Security Configuration menu is only available when the Administrator
Mode is active.
• In order to use domain names in the Allow List and/or Deny List, you must
first define IP address(es) for the desired Domain Name Server(s) as
described in Section 5.9.5.
1. Access the IP Security Configuration Menu. In the Text Interface, the IP Security
menu is accessed via the Network Configuration menu. In the Web Browser
Interface, the IP Security Configuration menu is accessed via the Network
Configuration flyout menu.
2. Allow List: Enter the IP Address(es) for the clients that you wish to allow. Note that
if an IP Address is found in the Allow list, the client will be allowed to connect, and
the AFS-16 will not check the Deny list.
a) Text Interface: Note the number for the first empty field in the Allow list, then
type that number at the command prompt, press [Enter], and then follow the
instructions in the resulting submenu.
b) Web Browser Interface: Place the cursor in the first empty field in the
parameters menu, then key in the desired IP Address, operators, wild cards,
and/or net/mask pairs.
3. Deny List: Enter the IP Address(es) for the clients that you wish to deny. Note that
if the client’s IP Address is not found in the Deny List, that client will be allowed to
connect. Use the same procedure for entering IP Addresses described in Step 2
above.

Basic Configuration
5.9.3.2. Linux Operators and Wild Cards
In addition to merely entering a specific IP address or partial IP address in the Allow or
Deny list, you may also use any standard Linux operator or wild card. In most cases,
the only operator used is "EXCEPT" and the only wild card used is "ALL," but more
experienced Linux users may note that other operators and wild cards may also be
used.
EXCEPT:
This operator creates an exception in either the "allow" list or "deny" list.
For example, if the Allow list includes a line which reads "192. EXCEPT 192.255.255.6,"
then all IP address that begin with "192." will be allowed; except 192.255.255.6
(providing that this address appears in the Deny list.)
ALL:
The ALL wild card indicates that all IP Addresses should be allowed or denied. When
ALL is included in the Allow list, all IP addresses will be allowed to connect; conversely,
if ALL is included in the Deny list, all IP Addresses will be denied (except for IP
addresses listed in the Allow list.)
For example, if the Deny list includes a line which reads "ALL EXCEPT 168.255.192.192,"
then all IP addresses except 168.255.192.192 will be denied (except for IP addresses
that are listed in the Allow list.)
Net/Mask Pairs:
An expression of the form "n.n.n.n/m.m.m.m" is interpreted as a "net/mask" pair. A host
address is matched if "net" is equal to the bitwise AND of the address and the "mask."
For example, the net/mask pattern "131.155.72.0/255.255.254.0" matches every address
in the range "131.155.72.0" through "131.155.73.255."
5.9.3.3. IP Security Examples
1. Mostly Closed: Access is denied by default and the only clients allowed,
are those explicitly listed in the Allow list. To deny access to all clients except
192.255.255.192 and 168.112.112.05, the Allow and Deny lists would be defined as
follows:
• Allow List:
1. 192.255.255.192
2. 168.112.112.05
• Deny List:
1. ALL

Basic Configuration
2. Mostly Open: Access is granted by default, and the only clients denied access,
are those explicitly listed in the Deny list, and as exceptions in the Allow list. To
allow access to all clients except 192.255.255.192 and 168.112.112.05, the Allow
and Deny lists would be defined as follows:
• Allow List:
1. ALL EXCEPT 192.255.255.192, 168.112.112.05
• Deny List:
1. 192.255.255.192, 168.112.112.05
Notes:
• When defining a line in the Allow or Deny list that includes several IP
addresses, each individual address is separated by either a space, a comma,
or a comma and a space as shown in Example 2 above.
• Take care when using the "ALL" wild card. When ALL is included in the Allow
list, it should always include an EXCEPT operator in order to allow the unit to
proceed to the Deny list and determine any addresses you wish to deny.
5.9.4. Static Route
The Static Route menu allows you to type in Linux routing commands that will be
automatically executed each time that the unit powers up or reboots. In the Text
Interface, the Static Route menu is accessed via the Network Configuration menu. In
the Web Browser Interface, the Static Route menu via the Network Configuration
flyout menu.
5.9.5. Domain Name Server
The DNS menu is used to select IP addresses for Domain Name Servers. When web
and network addresses are entered, the Domain Name Server interprets domain names
(e.g., www.yourcompanyname123.com), and translates them into IP addresses. Note
that if you don't define at least one DNS, then IP addresses must be used, rather than
domain names.

5.9.6. SNMP Access Parameters
These menus are used to select access parameters for the SNMP feature. The SNMP
Access Parameters menus allow the following parameters to be defined:
Note: After you have configured SNMP Access Parameters, you will then be
able to manage the AFS-16's User Directory and display unit status via SNMP, as
described in Section 13.
• Enable: Enables/disables SNMP Polling. (Default = Off.)
Note: This item only applies to external SNMP polling of the AFS-16; it does
not effect the ability of the AFS-16 to send SNMP traps.
• Version: This parameter determines which SNMP Version the AFS-16 will respond
to. For example, if this item is set to V3, then clients who attempt to contact the
AFS-16 using SNMPv2 will not be allowed to connect. (Default = V1/V2 Only.)
• Read Only: Enables/Disables the "Read Only Mode", which controls the ability to
access configuration functions and invoke switching commands. When Enabled,
you will not be able to change configuration parameters or invoke other commands
when you contact the AFS-16 via SNMP. (Default = No.)
Note: In order to define user names for the AFS-16 via your SNMP client, the
Read Only feature must be disabled. When the Read Only feature is enabled,
you will not be able to issue configuration commands to the unit via SNMP.
• Authentication / Privacy: Configures the Authentication and Privacy features
for SNMPv3 communication. The Authentication / Privacy parameter offers two
options, which function as follows:
1. Auth/noPriv: An SNMPv3 username and password will be required at log in,
but encryption will not be used. (Default Setting.)
2. Auth/Priv: An SNMPv3 username and password will be required at log in, and
all messages will be sent using encryption.
Notes:
• The Authentication / Privacy item is not available when the Version parameter
is set to V1/V2.
• If the Version Parameter is set to V1/V2/V3 (all) and Authentication / Privacy
parameter is set to "Auth/Priv", then only V3 data will be encrypted.
• The AFS-16 supports DES encryption, but does not currently support the AES
protocol.
• The AFS-16 does not support "noAuth/noPriv" for SNMPv3 communication.
• SNMPv3 User Name: Sets the User Name for SNMPv3. Note that this option is
not available when the Version parameter is set to V1/V2. (Default = undefined.)

The AFS-16 supports both MD5 and SHA1 authentication. (Default = MD5.)
Notes:
• The Authentication Protocol that is selected for the AFS-16 must match the
protocol that your SNMP client will use when querying the AFS-16 unit.
• The Authentication Protocol option is not available when the Version
parameter is set to V1/V2
• SNMP Contact: (Default = undefined.)
• SNMP Location: (Default = undefined.)
• Read Only Community: Note that this parameter is not available when the SNMP
Version is set to V3. (Default = Public.)
• Read/Write Community: Note that this parameter is not available when the SNMP
Version is set to V3. (Default = Public.)
Note: If identical names are defined for the Read Only Community and
Read/Write Community, then the unit will give priority to the Read/Write
Community option.
5.9.7. SNMP Trap Parameters
These menus are used to select parameters that will be used when SNMP traps are
sent. For more information on SNMP Traps, please refer to Section 12. Text Interface
and Web Browser Interface allow the following parameters to be defined:
• SNMP Manager 1: The IP Address for the first SNMP Manager. For more

Basic Configuration
5.9.8. LDAP Parameters
The AFS-16 supports LDAP (Lightweight Directory Access Protocol,) which allows
authentication via the "Active Directory" network Directory Service. When LDAP is
enabled and properly configured, command access rights can be granted to new users
without the need to define individual new accounts at each AFS-16 unit, and existing
users can also be removed without the need to delete the account from each
AFS-16 unit. This type of authentication also allows administrators to assign users
to LDAP groups, and then specify which circuits the members of each group will be
allowed to control at each AFS-16 unit.
In order to apply the LDAP feature, you must first define User Names and associated
Passwords and group membership via your LDAP server, and then access the AFS-16
command mode to enable and configure the LDAP settings and define port access
rights and command access rights for each group that you have specified at the LDAP
server. Note that in order to access the LDAP Parameters menu, you must login to AFS-
16 command mode using a password that permits Administrator level commands.
Notes:
• Circuit access rights are not defined at the LDAP server. They are defined via
the LDAP Group configuration menu on each AFS-16 unit and are specific to
that AFS-16 unit alone.
• When LDAP is enabled and properly configured, LDAP authentication will
supersede any passwords and access rights that have been defined via the
AFS-16 user directory.
• If no LDAP groups are defined on a given AFS-16 unit, then access rights will
be determined as specified by the "default" LDAP group.
• The "default" LDAP group cannot be deleted.
The LDAP Parameters Menu allows the following parameters to be defined:
• Enable: Enables/disables LDAP authentication. (Default = Off.)
• Primary Host: Defines the IP address or domain name (up to 64 characters) for
the primary LDAP server. (Default = undefined.)
• Secondary Host: Defines the IP address or domain name (up to 64 characters) for
the secondary (fallback) LDAP server. (Default = undefined.)
• LDAP Port: Defines the port that will be used to communicate with the LDAP
server. (Default = 389.)
• TLS/SSL: Enables/Disables TLS/SSL encryption. Note that when TLS/SSL
encryption is enabled, the LDAP Port should be set to 636. (Default = Off.)
• Bind Type: Sets the LDAP bind request password type. Note that in the Text
Interface, when the Bind Type is set to "Kerberos" LDAP, the menu will include an
additional prompt (item 14) that is used to select Kerberos parameters as described
in Section 5.9.8.5. In the Web Interface, the button which is used to access the
Kerberos Parameters menu is located at the bottom of the LDAP Parameters Menu.
(Default = Simple.)
• Search Bind DN: Selects the user name who is allowed to search the LDAP
directory. (Default = undefined.)

the LDAP directory. (Default = undefined.)
• User Search Base DN: Sets the directory location for user searches.
(Default = undefined.)
• User Search Filter: Selects the attribute that lists the user name. Note that this
attribute should always end with "=%S" (no quotes.) (Default = undefined.)
• Group Membership Attribute: Selects the attribute that lists group
membership(s). (Default = undefined.)
• Group Membership Value Type: (Default = DN.)
• Fallback: Enables/Disables the LDAP fallback feature. When enabled, the
AFS-16 will revert to it's own internal user directory (see Section 5.5) if no defined
users are found via the LDAP server. In this case, port access rights will then be
granted as specified in the default LDAP group. (Default = Off.)
• LDAP Group Setup: Provides access to a submenu, which is used to define LDAP
Groups as described in the Sections 5.9.8.1 through 5.9.8.4.
• LDAP Kerberos Setup: Provides access to the Kerberos Setup menu as described
in Section 5.9.8.5. When the Bind Type is set to "Kerberos", the Kerberos Setup
menu is used to select Kerberos parameters. In the Text Interface, the link to the
Kerberos Setup menu will not be displayed unless the Bind Type is set to Kerberos.
5.9.8.1. Adding LDAP Groups
Once you have defined several users and passwords via your LDAP server, and
assigned those users to LDAP Groups, you must then grant access rights to each LDAP
Group at each AFS-16 unit. In order to add LDAP groups, you must log in to command
mode using a password that permits access to Administrator level commands. The Add
LDAP Group menu allows the following parameters to be defined:
• Group Name: Note that this name must match the LDAP Group names that you
have assigned to users at your LDAP server. (Default = undefined.)
• Access Level: Sets the command access level. For more information, please refer
to Section 5.4.1. (Default = User.)
• Circuit Access: This item is used to select the AFS-16 Circuit Modules that
members of this LDAP group will be allowed to connect. (Default = All Circuits Off.)
• Circuit Group Access: This item is used to determine which Circuit Groups the
members of this LDAP Group will be allowed to control. (Default = undefined.)
• Service Access: This item determines how members of this LDAP Group will be
allowed to access command mode and whether or not they will be able to create
outbound Telnet connections. The Service Access parameter is used to allow
members of this LDAP group to access command mode via Serial Port, Telnet/SSH
or any combination thereof, and also enables/disables Outbound Telnet.
(Default; Serial Port = On, Telnet/SSH = On, Outbound Access = Off.)
Note: After you have defined LDAP Group parameters, make certain to save
the changes before proceeding. In the Web Browser Interface, click on the
"Add LDAP Group" button to save parameters; in the Text Interface, press the
[Esc] key several times until the "Saving Configuration" message is displayed.

5.9.8.2 Viewing LDAP Groups
If you need to examine an existing LDAP group definition, the "View LDAP Groups"
function can be used to review the group's parameters and Circuit Access settings.
5.9.8.3. Modifying LDAP Groups
If you need to modify an existing LDAP Group in order to change parameters or circuit
access rights, the "Modify LDAP Group" function can be used to reconfigure group
parameters. To Modify an existing LDAP Group, access the AFS-16 command mode
using a password that permits access to Administrator Level commands. Once you
have accessed the Modify LDAP Group menu, use the menu options to redefine
parameters in the same manner that is used for the Add LDAP Group menu, as
discussed in Section 5.9.8.1.
Note: After you have defined LDAP Group parameters, make certain to save
the changes before proceeding. In the Web Browser Interface, click on the
"Modify LDAP Group" button to save parameters; in the Text Interface, press the
[Esc] key several times until the "Saving Configuration" message is displayed.
5.9.8.4. Deleting LDAP Groups
The Delete LDAP Group function is used to delete LDAP Groups that are no longer
needed. To delete an existing LDAP Group, you must access command mode using a
password that permits access to Administrator Level commands.
5.9.8.5. LDAP Kerberos Set Up
Kerberos is a network authentication protocol, which provides a secure means of
identity verification for users who are communicating via a non-secure network. To
display the LDAP Kerberos Set Up menu, you must access command mode using a
password that permits access to Administrator Level commands.
The LDAP Kerberos Setup menu allows you to define the following parameters:

5.9.9. TACACS Parameters
The TACACS Configuration Menus offer the following options:
• Enable: Enables/disables the TACACS feature at the Network Port. (Default = Off.)
• Primary Address: Defines the IP address or domain name (up to 64 characters)
for your primary TACACS server. (Default = undefined.)
• Secondary Address: Defines the IP address or domain name (up to 64 characters)
for your secondary, fallback TACACS server (if present.) (Default = undefined.)
• Secret Word: Defines the shared TACACS Secret Word for both TACACS servers.
(Default = undefined.)
• Fallback Timer: Determines how long the AFS-16 will continue to attempt to
contact the primary TACACS Server before falling back to the secondary TACACS
Server. (Default = 15 Seconds.)
• Fallback Local: Determines whether or not the AFS-16 will fallback to its own
password/username directory when an authentication attempt fails. When enabled,
the AFS-16 will first attempt to authenticate the password by checking the TACACS
Server; if this fails, the AFS-16 will then attempt to authenticate the password by
checking its own internal username directory. This Parameter offers three options:
Off: Fallback Local is disabled (Default.)
On (All Failures): Fallback Local is enabled, and the unit will fallback to it's own
internal user directory when it cannot contact the TACACS Server, or when a
password or username does not match the TACACS Server.
On (Transport Failure): Fallback Local is enabled, but the unit will only fallback
to it's own internal user directory when it cannot contact the TACACS Server.
• Authentication Port: The port number for the TACACS function. (Default = 49.)
• Default User Access: When enabled, this parameter allows TACACS users to
access the AFS-16 command mode without first defining a TACACS user account
on the AFS-16. When new TACACS users access the AFS-16 command mode,
they will inherit the default Access Level, Circuit Access, Circuit Group Access and
Service Access that are defined via the items listed below: (Default = On.)
Access Level: Selects the default Access Level setting for new TACACS users.
This option can set the default access level to "Administrator", "SuperUser",
"User" or "ViewOnly." For more information on Command Access Levels, please
refer to Section 5.4.1 and Section 17.2. (Default = User.)

Basic Configuration
Circuit Access: Selects the default Circuit Access setting for new TACACS
users. The Circuit Access setting determines which Circuit Module(s) each
account will be allowed to control. (Defaults; Administrator and SuperUser =
All Circuits On, User = All Circuits Off, ViewOnly = All Circuits Off.)
Notes:
• Administrator and SuperUser level accounts always have access to all
circuits.
• User level accounts will only have access to the circuits that are defined via
the "Circuit Access" parameter.
• ViewOnly accounts are not allowed to invoke switching commands.
Circuit Group Access: Selects the default Circuit Group Access setting for
new TACACS users. For more information on Circuit Groups, please refer to
Section 5.6. (Defaults; Administrator and SuperUser = All Circuit Groups On,
User = All Circuit Groups Off, ViewOnly = All Circuit Groups Off.)
Notes:
• In order to use this feature, Circuit Groups must first be defined as described
in Section 5.6.
• Administrator and SuperUser level accounts will always have access to all
Circuit Groups.
• User Level accounts will only have access to the Circuit groups that are
defined via the Circuit Group Access parameter.
• ViewOnly accounts are not allowed to invoke switching commands.
Service Access: Selects the default Service Access setting for new TACACS
users. The Service Access setting determines whether each account will be
able to access command mode via Serial Port, Telnet/SSH or Web. In addition,
the Service Access setting also determines whether each account will be able
to employ the Outbound Access function. For example, if Telnet/SSH Access is
disabled, then the default setting for new TACACS accounts will not allow access
to command mode via Telnet or SSH. (Default = Serial Port = On, Telnet/SSH =
On, Web = On.)
Note: If Outbound Access has been disabled via the Network Parameters
menu, then the Service Access parameter will not be allowed to grant Outbound
Access to new TACACS users.

• Fallback Timer: Determines how long the AFS-16 will continue to attempt to
contact the primary RADIUS Server before falling back to the secondary RADIUS
Server. (Default = 3 Seconds.)
• Fallback Local: Determines whether or not the AFS-16 will fallback to its own
password/username directory when an authentication attempt fails. When enabled,
the AFS-16 will first attempt to authenticate the password by checking the RADIUS
Server; if this fails, the AFS-16 will then attempt to authenticate the password by
checking its own internal username directory. This parameter offers three options:
Off: Fallback Local is disabled (Default.)
On (All Failures): Fallback Local is enabled, and the unit will fallback to it's
own internal user directory when it cannot contact the Radius Server, or when a
password or username does not match the Radius Server.
On (Transport Failure): Fallback Local is enabled, but the unit will only fallback
to it's own internal user directory when it cannot contact the Radius Server.
• Retries: Determines how many times the AFS-16 will attempt to contact the

Dictionary Support for RADIUS
The RADIUS dictionary file can allow you to define a user and assign command access
rights and port access rights from a central location. The RADIUS dictionary file,
"dictionary.wti" is included on the CDROM along with this user's guide. To install the
dictionary file on your RADIUS server, please refer to the documentation provided with
your server; some servers will require the dictionary file to reside in a specific directory
location, others will require the dictionary file to be appended to an existing RADIUS
dictionary file. The WTI RADIUS dictionary file provides the following commands:
• WTI-Super- Sets the command access level for the user. This command provides
the following arguments:
0= ViewOnly
1= User
2= SuperUser
3= Administrator
For example, in order to set command access level to "SuperUser", the command
line would be:
WTI-Super="2"
• WTI-Circuit-Access- Determines which circuit(s) the user will be allowed to
access. This command provides an argument that consists of a four character
string, with one character for each the AFS-16's Circuit Modules. The following
options are available for each switched circuit:
0= Off (Deny Access)
1= On (Allow Access)
For example, to allow access to Circuits 2 and 4, the command line would be:
WTI-Circuit-Access="0101"
• WTI-Group-Access- Determines which Circuit Group(s) the user will be allowed
to access. The argument for this command includes a character for each, defined
Circuit Group, with the first character in the string being used to represent the first
Circuit Group defined, and the last character in the string representing the last
Circuit Group defined. The following options are available for each Circuit Group:
0= Off (Deny Access)
1= On (Allow Access)
For example, to allow access to the first three defined Circuit Groups out of a total
of six defined Circuit Groups, the command line would be:
WTI-Group-Access="111000"
Example:
The following command could be used to set the command access level to "User", allow
access to Circuits 1 and 2, and also allow access to the first two of five defined
Circuit Groups:
tom Auth-Type:=Local, User-Password=="tom1"
Login-Service=Telnet,
Login-TCP-Port=Telnet,
User-Name="HARRY-tom",
WTI-Super="1",

Basic Configuration
5.10. Save User Selected Parameters
It is strongly recommended to save all user-defined parameters to an ASCII file as
described in Section 15. This will allow quick recovery in the event of accidental
deletion or reconfiguration of port parameters.
When changing configuration parameters via the Text Interface, make certain that the
AFS-16 has saved the newly defined parameters before exiting from command mode.
To save parameters, press the [Esc] key several times until you have exited from all
configuration menus and the AFS-16 displays the "Saving Configuration" menu and
the cursor returns to the command prompt. If newly defined configuration parameters
are not saved prior to exiting from command mode, then the AFS-16 will revert to the
previously saved configuration after you exit from command mode.
5.10.1. Restore Configuration
If you make a mistake while configuring the AFS-16 unit, and wish to return to the
previously saved parameters, the Text Interface's "Reboot System" command (/I) offers
the option to reinitialize the unit using previously backed up parameters. This allows
you to reset the unit to previously saved parameters, even after you have changed
parameters and saved them.
Notes:
• The AFS-16 will automatically backup saved parameters once a day, shortly
after Midnight. This configuration backup file will contain only the most
recently saved AFS-16 parameters, and will be overwritten by the next night's
daily backup.
• When the /I command is invoked, a submenu will be displayed which
offers several Reboot options. Option 4 is used to restore the configuration
backup file. The date shown next to Option 4 indicates the date that you last
changed and saved unit parameters.
• If the daily automatic configuration backup has been triggered since the
configuration error was made, and the previously saved configuration has
been overwritten by newer, incorrect parameters, then this function will not
be able to restore the previously saved (correct) parameters.
To restore the previously saved configuration, proceed as follows:
1. Access command move via the Text Interface, using a username/password that
permits access to Administrator level commands (see Section 5.1.1.)
2. At the AFS command prompt, type /Iand press [Enter]. The AFS-16 will display a
submenu that offers several different reboot options.
3. At the submenu, you may choose either Item 4 (Reboot & Restore Last Known
Working Configuration.) Type 4, and then press [Enter].
4. The AFS-16 will reboot and previously saved parameters will be restored.

7. Alarm Configuration
The AFS-16 can generate alarms when temperature readings exceed user-defined
trigger levels, when input voltage is lost and then restored to the unit, when a Ping-No-
Answer condition is detected and when the Invalid Access Lockout feature is triggered.
In addition, the AFS-16 can also generate an alarm when the Monitor/Alarm Input
feature detects a signal change at the Control Module AUX connector. When any of
these conditions are detected, the AFS-16 can send an "Alarm" to the proper personnel
via Email, Syslog Message or SNMP trap.
Notes:
• In order to send alarm notification via email or text message, email addresses
and parameters must first be defined as described in Section 5.9.11.
Email alarm notification will then be sent for all alarms that are enabled as
described in this Section.
• In order to send alarm notification via Syslog Message, a Syslog address
must first be defined as described in Section 5.9.2. Once the Syslog address
has been defined, Syslog Messages will be sent for every alarm discussed
in this Section, providing that the Trigger Enable parameter for the alarm has
been set to "On."
• In order to send alarm notification via SNMP Trap, SNMP Trap parameters
must first be defined as described in Section 5.9.7. Once SNMP Trap

7.2. The Over Temperature Alarms
The Over Temperature Alarms are designed to inform you when the temperature level
inside your equipment rack reaches or exceeds certain user-defined levels. There
are two separate Over Temperature Alarms; the Initial Threshold alarm and the Critical
Threshold Alarm.
Typically, the Initial Threshold alarm is used to notify you when the temperature within
your equipment rack reaches a point where you might want to investigate it, whereas the
Critical Threshold alarm is used to notify you when the temperature approaches a level
that may harm equipment or inhibit performance. The trigger for the Initial Threshold
alarm is generally set lower than the Critical Threshold alarm.
If the user-defined trigger levels for temperature are exceeded, the AFS-16 can also
enable the Contact Output on the AFS-16 Control Module's AUX connector.
To configure the Over Temperature Alarms, access the AFS-16 command mode using
a password that permits Administrator Level commands, and then use the Alarm
Configuration menu to select the desired alarm feature.
Note that both the Initial Threshold menus and Critical Threshold menus offer essentially
the same set of parameters, but the parameters defined for each alarm are separate
and unique. Therefore, parameters defined for the Critical Threshold Alarm will not be
applied to the Initial Threshold Alarm and vice versa.
Both the Over Temperature (Initial Threshold) alarm and the Over Temperature (Critical
Threshold) alarm offer the following parameters:
• Trigger Enable: Enables/Disables the trigger for this alarm. When Disabled, this
alarm will be suppressed. (Default = On.)
Note: To cancel an alarm without correcting the condition that caused the
alarm, simply toggle the Trigger Enable parameter Off and then back On again.
Alarm Set Threshold: The trigger level for this alarm. When temperature
exceeds the Alarm Set Threshold, the AFS-16 can send an alarm (if enabled.)
(Initial Threshold: Default = 90°F or 32°C, Critical Threshold: Default = 100°F or
38°C.)
Alarm Clear Threshold: Determines how low the temperature must drop in
order for the Alarm condition to be cancelled. (Initial Threshold: Default = 80°F
or 27°C, Critical Threshold: Default = 90°F or 38°C.)
Note: The System Parameters menu is used to set the temperature format for
the AFS-16 unit to either Fahrenheit or Celsius as described in Section 5.3.
• Resend Delay: Determines how long the AFS-16 will wait to resend a message
generated by this alarm, when the initial attempt to send notification was
unsuccessful. (Default = 60 Minutes.)
• Notify Upon Clear: When this item is enabled, the AFS-16 will send additional
notification when the situation that caused the alarm has been corrected. For
example, when Notify Upon Clear is enabled, the AFS-16 will send initial notification
when it detects that the temperature has exceeded the trigger value, and then send
a second notification when it determines that the temperature has fallen below the
trigger value. (Default = On.)

7.3. The Ping-No-Answer Alarm
The Ping-No-Answer Alarm is intended to provide notification when one of the IP
addresses defined via the Ping-No-Answer function (as described in Section 6) fails
to respond to a Ping command. When one of the user-defined IP addresses fails
to answer a Ping command, the AFS-16 can provide notification via Email, Syslog
Message or SNMP Trap.
Notes:
• In order for this alarm to function, IP Addresses for the Ping-No-Answer
function must first be defined as described in Section 6.1.
• When a Ping-No-Answer condition is detected, the AFS-16 can still switch
the user-selected Circuit Module(s) as described in Section 6, and can also
send an email, Syslog Message and/or SNMP trap if properly configured as
described in this section.
7.3.1. Defining Ping-No-Answer IP Addresses
In order for the Ping-No-Answer Alarm to function, you must first define at least one
Ping-No-Answer profile as described in Section 6. To define a Ping-No-Answer profile
and associated IP address, proceed as described in Section 6.
Note: To define Ping-No-Answer IP addresses for the Ping-No-Answer Alarm,
without enabling the A/B switching function, make certain that the "Toggle"
option in the Add Ping-No-Answer Profile menu is set to "No."
7.3.2. Configuring the Ping-No-Answer Alarm

7.4. The Invalid Access Lockout Alarm
The Invalid Access Lockout Alarm can provide notification when the AFS-16 has locked
a port due to repeated, invalid attempts to access command mode. Normally, the
Invalid Access Lockout feature (discussed in Section 5.3.2) will lock a port whenever the
AFS-16 detects that a user-defined number of invalid passwords have been entered at
the port. When the Invalid Access Lockout Alarm is properly configured and enabled
as described in this section, the AFS-16 can also provide notification via Email, Syslog
Message or SNMP Trap.
Notes:
• In order for this alarm to function, Invalid Access Lockout parameters must
first be configured and enabled as described in Section 5.3.2.
• When an Invalid Access Lockout occurs, the AFS-16 can still lock the
network port as described in Section 5.3.2, and can also send an email,
Syslog Message and/or SNMP trap if properly configured.
• If desired, the AFS-16 can be configured to count Invalid Access attempts
and provide notification when the counter exceeds a user defined trigger
level, without actually locking the port in question. To do this, enable the
Invalid Access Lockout Alarm as described here, but when you configure

10. Telnet & SSH Functions
10.1. SSH Encryption
In addition to standard Telnet protocol, the AFS-16 also supports SSH connections,
which provide secure, encrypted access via network. In order to communicate with the
AFS-16 using SSH protocol, your network node must include an appropriate SSH client.
Note that when the /K (Send SSH Key) command is invoked, the AFS-16 can also
provide you with a public SSH key, which can be used to streamline connection to the
AFS-16 when using SSH protocol.
Although you can establish an SSH connection to the unit without the public key, the
public key provides validation for the AFS-16, and once this key is supplied to the SSH
client, the client will no longer display a warning indicating that the AFS-16 is not a
recognized user when the client attempts to establish a connection.
The /K command uses the following format:
/K <k> [Enter]
Where kis an argument that determines which type of public key will be displayed, and
the kargument offers the following options:
1. SSH1
2. SSH2 RSA
3. SSH2 DSA
For example, to obtain the public SSH key for an SSH2 RSA client, type
/K 2and then press [Enter].
Note: Although the AFS-16 does not support SSH1, the /K 1 command will still
return a key for SSH1.

10.3. Creating an Outbound SSH Connection
The AFS-16's /SSH command can be used to create an outbound SSH connection. In
order to use the /SSH command, you must access the AFS-16's Text Interface command
mode using an account that permits SSH Access and Outbound Access, via the AFS-16
Control Module's RS232 Serial Port as described below.
Notes:
• In order for the /SSH command to function, SSH Access and Outbound
Service Access must be enabled for your user account as described in
Section 5.5.
• If are communicating with the AFS-16 unit via the Network Port, the /SSH
command will not function.
To create an outbound SSH connection, access the Text Interface via the Control
Module's RS232 Serial Port using an account that permits SSH Access and Outbound
Access and then invoke the /SSH command using the following format:
/SSH <ip> -l <username> [Enter]
Where:
ip
Is the target IP address.
-l
(Lowercase letter "L") Indicates that the next argument will be the
log on name.
username
Is the username that you wish to use to log in to the target device.
For example, to create an outbound SSH connection to a device at IP Address
255.255.255.255, with the username "employee", access the Text Interface command
mode via a free AFS-16 Serial Port using an account that permits SSH Access and
Outbound Access and invoke the SSH command as follows:
/SSH 255.255.255.255 -l employee [Enter]

11. Syslog Messages
The Syslog feature can create log records of each Alarm Event. As these event records
are created, they are sent to a Syslog Daemon, located at an IP address defined via the
Network Parameters menu.
11.1. Configuration
In order to employ this feature, you must set the real-time clock and calendar via the
System Parameters Menu, and define the IP address for the Syslog Daemon via the
Network Port Configuration menu.
To configure the Syslog function, please proceed as follows:
1. Access command mode: Note that the following configuration menus are only
available to accounts that permit Administrator level commands.
2. System Parameters Menu: Access the System Parameters Menu as described in
Section 5.3, then set the following parameters:
a) Set Clock and Calendar: Set the Real Time Clock and Calendar and/or
configure and enable the NTP server feature.
3. Network Parameters Menu: Access the Network Parameters Menu as described
in Section 5.9, then set the following parameters:
a) Syslog IP Address: Determine the IP address for the device that will run the
Syslog Daemon, then use the Network Port Configuration menu to define the IP
Address for the Syslog Daemon.
4. Syslog Daemon: In order to capture messages sent by the AFS-16, a computer
must be running a Syslog Daemon (set to UDP Port 514) at the IP address specified
in Step 3 above.
Once the Syslog Address is defined, Syslog messages will be generated whenever one
of the alarms discussed in Section 7 is triggered.

12. SNMP Traps
SNMP is an acronym for "Simple Network Management Protocol". The SNMP Trap
function allows the AFS-16 to send Alarm Notification messages to two different SNMP
managers, each time one of the Alarms discussed in Section 7 is triggered.
Note:
• The SNMP feature cannot be configured via the SNMP Manager.
• SNMP reading ability is limited to the System Group.
• The SNMP feature includes the ability to be polled by an SNMP Manager.
• Once SNMP Trap Parameters have been defined, SNMP Traps will be sent
each time an Alarm is triggered and/or when a Buffer Mode serial port
reaches the user-defined Buffer Threshold value. For more information on
Alarm Configuration, please refer to Section 7.
12.1. Configuration:
To configure the SNMP Trap function, proceed as follows:
1. Access command mode using an account that permits access to Administrator
level commands.
2. SNMP Trap Parameters: Access the SNMP Trap Parameters Menu as described in
Section 5.9.7. Set the following:
a) SNMP Managers 1 and 2: The address(es) that will receive SNMP Traps
that are generated by one of the Alarms discussed in Section 7. Consult
your network administrator to determine the IP address(es) for the SNMP
Manager(s), then use the Network Parameters menu to set the IP address
for each SNMP Manager. Note that it is not necessary to define both SNMP
Managers.
Note: To enable the SNMP Trap feature, you must define at least one SNMP
Manager. SNMP Traps are automatically enabled when at least one SNMP
Manager has been defined.
b) Trap Community: Consult your network administrator, and then use the
Network Parameters menus to set the Trap Community.
Once SNMP Trap Parameters have been defined, the AFS-16 will send an SNMP Trap
each time an alarm is triggered.

13. Operation via SNMP
If SNMP Access Parameters have been defined as described in Section 5.9.6, then you
will be able to manage user accounts, control power and reboot switching and display
unit status via SNMP. This section describes SNMP communication with the
AFS-16 unit, and lists some common commands that can be employed to manage
users, control switching and reboot actions and display unit status.
13.1. AFS-16 SNMP Agent
The AFS-16’s SNMP Agent supports various configuration, control, status and event
notification capabilities. Managed objects are described in the WTI-AFS-MIB.txt
document, which can be found on the CDROM included with the AFS-16 unit, or on the
WTI web site (http://www.wti.com). The WTI-AFS-MIB.txt document can be compiled for
use with your SNMP client.
13.2. SNMPv3 Authentication and Encryption
For SNMPv3, the AFS-16 supports two forms of Authentication/Privacy: Auth/noPriv
which requires a username/password, but does not encrypt data going over the internet
and Auth/Priv which requires a username/password AND encrypts the data going over
the internet using DES (AES is not supported at this time). For the Password protocol,
the AFS-16 supports either MD5 or SHA1.
13.3. Configuration via SNMP
AFS-16 User accounts can be viewed, created, modified, and deleted via SNMP. User
accounts are arranged in a table of 128 rows, and indexed 1-128. User account
parameters, as seen through the SNMP, are summarized below.

14 Setting Up SSL Encryption
This section describes the procedure for setting up a secure connection via an https
web connection to the AFS-16.
Note: SSL parameters cannot be defined via the Web Browser Interface.
In order to set up SSL encryption, you must contact the AFS-16 via the Text
Interface.
There are two different types of https security certificates: "Self Signed" certificates and
"Signed" certificates.
Self Signed certificates can be created by the AFS-16, without the need to go to an
outside service, and there is no need to set up your domain name server to recognize
the AFS-16. The principal disadvantage of Self Signed certificates, is that when you
access the AFS-16 command mode via the Web Browser Interface, the browser will
display a message which warns that the connection might be unsafe. Note however,
that even though this message is displayed, communication will still be encrypted, and
the message is merely a warning that the AFS-16 is not recognized and that you may
not be connecting to the site that you intended.
®
Signed certificates must be created via an outside security service (e.g., VeriSign ,
Thawte™, etc.) and then uploaded to the AFS-16 unit to verify the user's identity. In
order to use Signed certificates, you must contact an appropriate security service and
set up your domain name server to recognize the name that you will assign to the
AFS-16 unit (e.g., service.wti.com.) Once a signed certificate has been created and
uploaded to the AFS-16, you will then be able to access command mode without seeing
the warning message that is normally displayed for Self Signed certificate access.

parameters. Although most SSL applications require only the Common Name,
in the case of the AFS-16 all of the following parameters are mandatory.
• 5. Common Name: A domain name, that will be used to identify the AFS-16
unit. If you will use a Self Signed certificate, then this name can be any name
that you choose, and there is no need to set up your domain name server to
recognize this name. However, if you will use a Signed certificate, then your
domain name server must be set up to recognize this name
(e.g., service.yourcompanyname.com.)
• 6. State or Province: The name of the state or province where the AFS-16 unit
will be located (e.g., California.)
• 7. Locality: The city or town where the AFS-16 unit will be located (e.g., Irvine.)
• 8. Country: The two character country code for the nation where the AFS-16
will be located (e.g., US.)
• 9. Email Address: An email address, that can be used to contact the person
responsible for the AFS-16 (e.g., [email protected].)
• 10. Organizational Name: The name of your company or organization
(e.g., Yourcompanyname, Inc.)
• 11. Organizational Unit: The name of your department or division; if necessary,
any random text can be entered in this field (e.g., tech support.)

5. After the new configuration has been saved, test the Self Signed certificate by
accessing the AFS-16 via the Web Interface, using an HTTPS connection.
a) Before the connection is established, the AFS-16 should display the warning
message described previously. This indicates that the Self Signed certificate
has been successfully created and saved.
b) Click on the "Yes" button to proceed. The AFS-16 will prompt you to enter
a user name and password. After keying in your password, the main menu
should be displayed, indicating that you have successfully accessed command
mode.
14.2. Creating a Signed Certificate
To create a Signed certificate, and eliminate the warning message, first set up your
domain name server to recognize the Common Name (item 5) that you will assign to
the unit. Next, complete steps one through five as described in Section 14.1 and then
proceed as follows:
1. Capture the Newly Created Certificate: Type 13and press [Enter] (View CSR).
The AFS-16 will prompt you to configure your communications (Telnet) program to
receive the certificate. Set up your communications program to receive a binary
file, and then press [Enter] to capture the file and save it. This is the Code Signing
Request that you will send to the outside security service (e.g., VeriSign, Thawte,
etc.) in order to have them sign and activate the certificate.
2. Obtain the Signed Certificate: Send the captured certificate to the outside
security service. Refer to the security service's web page for further instructions.

4. After the configuration has been saved, test the signed certificate by accessing the
AFS-16 via the Web Browser Interface, using an HTTPS connection. For example,
if the common name has been defined as "service.wti.com", then you would enter
"https://service.wti.com" in your web browser's address field. If the Signed
Certificate has been properly created and uploaded, the warning message should
no longer be displayed.
14.3. Downloading the Server Private Key
When configuring the AFS-16's SSL encryption feature (or setting up other security/
authentication features), it is recommended to download and save the Server Private
Key. To download the Server Private Key, access the Text interface via Telnet or SSH,
using a password that permits access to Administrator level commands and then
proceed as follows:
1. Type /Nand press [Enter] to display the Network Parameters menu.
2. At the Network Parameters menu, type 23and press [Enter] to display the Web
Access menu (Figure 14.1.)

15. Saving and Restoring Configuration Parameters
Once the AFS-16 is properly configured, parameters can be downloaded and saved as
an ASCII text file. Later, if the configuration is accidentally altered, the saved parameters
can be uploaded to automatically reconfigure the unit without the need to manually
assign each parameter.
Saved parameters can also be uploaded to other identical AFS-16 units, allowing rapid
set-up when several identical units will be configured with the same parameters.
The "Save Parameters" procedure can be performed from any terminal emulation
©
program (e.g. HyperTerminal™, TeraTerm , etc.), that allows downloading of ASCII files.
Note: The Save and Restore features described in this section are only
available via the Text Interface.
15.1. Sending Parameters to a File
1. Start your terminal emulation program and access the Text Interface command

Saving and Restoring Configuration Parameters
15.3. Restoring Previously Saved Parameters
If you make a mistake while configuring the AFS-16 unit, and wish to return to the
previously saved parameters, the Text Interface's "Reboot System" command (/I) offers
the option to reinitialize the AFS-16 using previously backed up parameters. This allows
you to reset the unit to previously saved parameters, even after you have changed
parameters and saved them.
Notes:
• The AFS-16 will automatically backup saved parameters once a day, shortly
after Midnight. This configuration backup file will contain only the most
recently saved AFS-16 parameters, and will be overwritten by the next night's
daily backup.
• When the /I command is invoked, a submenu will be displayed which offers
several Reboot options. Option 4 is used to restore the configuration backup
file. The date shown next to option 4 indicates the date that you last changed
and saved unit parameters.
• If the daily automatic configuration backup has been triggered since the
configuration error was made, and the previously saved configuration has
been overwritten by newer, incorrect parameters, then this function will not
be able to restore the previously saved (correct) parameters.
To restore the previously saved configuration, proceed as follows:
1. Access command move via the Text Interface, using a username/password that
permits access to Administrator level commands (see Section 5.1.1.)
2. At the RSM command prompt, type /Iand press [Enter]. The AFS-16 will display
a submenu that offers several different reboot options.
3. At the submenu, select Item 4 (Reboot & Restore Last Known Working
Configuration,) type 4, and then press [Enter].
4. The AFS-16 will reboot and previously saved parameters will be restored.

16. Upgrading AFS-16 Firmware
When new, improved versions of the AFS-16 firmware become available, the "Upgrade
Firmware" function can be used to update the unit. Updates can be uploaded via FTP
or SFTP protocols.
Notes:
• The FTP/SFTP servers can only be started via the Text Interface.
• All other ports will remain active during the firmware upgrade procedure.
• If the upgrade includes new parameters or features not included in the
previous firmware version, these new parameters will be set to their default
values.
• The upgrade procedure will require approximately 15 minutes.
1. Obtain the update file. Firmware modifications can either be mailed to the
customer, or downloaded from WTI. Place the upgrade CDR in your disk drive or
copy the file to your hard drive.
2. Access Text Interface command mode via Serial Port, Telnet or SSH client session,
using a username/password and port that permit Administrator level commands.
3. When the command prompt appears, type /UFand then press [Enter]. The
AFS-16 will display a screen which offers the following options:
a) Start FTP/SFTP Servers Only (Do NOT default parameters): To proceed
with the upgrade, while retaining user-defined parameters, type 1and press
[Enter]. All existing parameter settings will be restored when the upgrade is
complete.
b) Start FTP/SFTP Servers & Default (Keep IP parameters & SSH Keys): To
proceed with the upgrade and default al user-defined parameters except for the
IP Parameters and SSH Keys, type 2and press [Enter]. When the upgrade is
complete, all parameter settings except the IP Parameters and SSH Keys, will
be reset to factory default values.
c) Start FTP/SFTP Servers & Default (Default ALL parameters): To proceed
with the upgrade, and reset parameters to default settings, type 3and press
[Enter]. When the upgrade is complete, all parameters will be set to default
values.
d) Start FTP/SFTP Servers for Slip Stream Upgrade: This option will upgrade
only the WTI Management Utility, without updating the AFS-16's operating
firmware. To update the WTI Management Utility only, type 4and
press [Enter].
Note that after any of the above options is selected, the AFS-16 will start the
receiving servers and wait for an FTP/SFTP client to make a connection and upload
a valid firmware binary image.

Upgrading RSM-8R4 Firmware
4. To proceed with the upgrade, select either option 1 or option 2. The AFS-16 will
display a message that indicates that the unit is waiting for data. Leave the current
Telnet/SSH client session connected at this time.
5. Open your FTP/SFTP application and (if you have not already done so,) login to the
AFS-16 unit, using a username and password that permit access to Administrator
Level commands.
6. Transfer the md5 format upgrade file to the AFS-16.
7. After the file transfer is complete, the AFS-16 will install the upgrade file and then
reboot itself and break all port connections. Note that it will take approximately 10
minutes to complete the installation process. The unit will remain accessible until it
reboots.
a) Some FTP/SFTP applications may not automatically close when the file transfer
is complete. If this is the case, you may close your FTP/SFTP client manually
after it indicates that the file has been successfully transferred.
b) When the upgrade process is complete, the AFS-16 will send a message to
all currently connected network sessions, indicating that the AFS-16 is going
down for a reboot.
Note: Do not power down the AFS-16 unit while it is in the process of installing
the upgrade file. This can damage the unit's operating system.
8. If you have accessed the AFS-16 via the Network Port, in order to start the FTP/
SFTP servers, the AFS-16 will break the network connection when the system is
reinitialized.
• If you initially selected "Start FTP/SFTP Servers and Save Parameters", you may
then reestablish a connection with the AFS-16 using your former IP address.
• If you initially selected "Start FTP/SFTP Servers and Default Parameters",
you must then login using the AFS-16’s default IP address (Default =
192.168.168.168) or access command mode via Serial Port 1 or via Modem.
When firmware upgrades are available, WTI will provide the necessary files. At that time,
an updated Users Guide or addendum will also be available.

17.1. Command Conventions
Most commands described in this section conform to the following conventions:
• Text Interface: Commands discussed in this section, can only be invoked via the
Text Interface. These commands cannot be invoked via the Web Browser Interface.
• Slash Character: Most AFS-16 Text Interface commands begin with the Slash
Character (/).
• Apply Command to All Circuits: When an asterisk is entered as the argument of
the /T(Toggle), /TA(Toggle to A) or /TBcommands (Toggle to B) the command
will be applied to all circuits. For example, to switch all circuits to "A", type
/TA * [Enter].
• Circuit Name Wild Card: It is not always necessary to enter the entire circuit
name. Circuit names can be abbreviated in command lines by entering the first
character(s) of the name followed by an asterisk (*). For example, a circuit named
"SERVER" could be specified as "S*". Note however, that this command would also
be applied to any other circuit name that begins with an "S".
• Suppress Command Confirmation Prompt: When the commands are invoked,
the ",Y" option can be included to override the Command Confirmation ("Sure?")
prompt. For example, to switch Circuit 4 to the "B" position without displaying the
Sure prompt, type /TB 4,Y [Enter].
• Enter Key: Most commands are invoked by pressing [Enter].
