9G421-02/9G429-02 Module Specific Information  
General Configuration Screen Fields  
The following information briefly explains each General Configuration Screen  
field.  
Module Serial #  
Displays the serial number of the selected module.  
Module Board Revision  
Displays the version number of the selected module.  
FLASH Memory  
Displays the amount (megabytes) of flash memory in the selected module.  
Module Date  
Contains a value that the module recognizes as the current date. To enter a new  
date, highlight the field and enter the date in MM/DD/YYYY format. The month  
and day portion of the date must include two digits. Therefore, enter a leading  
zero for months January through September, and for dates less than 10. For  
example, for June 4, 1996, enter 06/04/1996 (slashes are optional). If you do not  
enter slashes to separate the month, day, and year values, the first eight digits you  
enter in this field represent an entry (i.e., 06041996).  
Module Time  
Contains a value that the module recognizes as the current time. To enter a new  
time, highlight the field and enter the time in HH:MM:SS format. Notice that  
there is no AM/PM indicator. Time should be entered based upon a 24-hour  
clock. For 4:07 p.m., enter 16:07:00 (colons are optional). If you do not enter colons  
to separate the hours, minutes, and seconds values, the first six digits you enter in  
this field represent an entry (i.e., 160700). For 6:12 a.m., enter 6:12:00 or 061200.  
The module’s default date and time settings are indeterminate. The internal  
calendar and clock begin running as soon as you install the module.  
NOTE  
Screen Refresh Time  
Contains the rate at which the module’s screens are updated. This setting  
determines how frequently (in seconds) information is updated on the screen. To  
enter a new refresh rate, highlight the field and enter a number. The default  
refresh rate is 3 seconds. The range is 3 - 99 seconds.

9G421-02/9G429-02 Module Specific Information  
Screen Lockout Time  
Contains the maximum number of minutes that the Local Management  
application will display a module’s screen while pending input or action from a  
user. For example, if you enter 5 in this field, users will have up to five minutes to  
respond in some fashion to each of the specified module’s Local Management  
screens. In our example, after five minutes of “idleness” (no input or action), the  
Local Management application terminates the session on the selected module and  
the Slot Selection Screen reappears. To enter a new lockout time, highlight the  
field and enter a number. The default lockout time is 15 minutes. The range is  
1 - 30 minutes.  
Host IP Address  
Contains the Internet Protocol address currently assigned to the selected module.  
Set this field according to your network requirements. Highlight the Host IP  
Address field and enter the desired IP address using dotted decimal notation (4  
decimal values between 1 and 255 separated by periods). For example,  
255.255.255.255.  
The maximum number that you can enter in any of the four segments is 255. The  
default is 0.0.0.0 . Any of the system interfaces on the module can use this  
address.  
Subnet Mask  
Contains the subnet mask for the selected module. A subnet mask “masks out”  
the network bits of the IP address by setting the bits in the mask to 1 when the  
network treats the corresponding bits in the IP address as part of the network or  
subnetwork address, or to 0 if the corresponding bit identifies the host. The  
default subnet mask uses the first two portions of the IP address to identify the  
network id, leaving the rest of the IP address to identify specific nodes. To enter a  
new subnet mask, highlight the field and enter a new value using dotted decimal  
notation (4 decimal values between 1 and 255 separated by periods). For example,  
255.255.255.255.  
(The Subnet Mask field defaults to the natural mask value, based on the IP  
Address that you entered for the device.)  
Default Gateway  
Contains the IP Address of the device to which all packets addressed to an  
unknown network or host are sent. If you do not configure a Default Gateway,  
any packets that are addressed to an unknown network or host will be dropped.  
This field is not defined until you enter an appropriate value using dotted  
decimal notation (4 decimal values between 1 and 255 separated by periods). The  
default is NONE DEFINED, meaning no default gateway selected.

9G421-02/9G429-02 Module Specific Information  
Default Interface  
Contains the number that represents the interface that is connected to the  
module’s Default Gateway. In some instances, dissimilar modules have different  
corresponding interface numbers. For example, if you are assigning a default  
interface to a 9E133-36 module and you enter a 3, then the default interface is the  
Flexible Network Bus. However, if you are assigning a default interface to a  
9F310-02 module and you enter a 3, then the default interface is the Internal  
Network Bus. See Table 1 for module-specific interface information. The default  
is NONE DEFINED, meaning no default interface selected.  
The Default Interface field becomes active after you enter an IP address in the  
Default Gateway field.  
NOTE  
Base MAC Address  
Displays the MAC Address of the selected module. This is the MAC Address of  
the SMB-10 interface.  
TFTP Gateway IP  
The IP address of the router that connects to or is closest to the module. Configure  
this address when you are performing TFTP downloads in a routed environment  
(if proxy ARP is disabled on the router).  
Exiting the General Configuration Screen  
To exit the General Configuration Screen, use the arrow keys to highlight  
RETURN, then press the Return key.

9G421-02/9G429-02 Module Specific Information  
Port Statistics Screen Fields  
The following information briefly explains each Port Statistics Screen field.  
PORT #  
Indicates the current port for which statistics are displayed.  
OCTETS  
Displays the number of octets transmitted and received on the port.  
PACKETS  
Displays the number of packets transmitted and received on the port.  
TOTAL ERRORS  
Displays the total number of errors on the port.  
COLLISIONS  
Displays the total number of collisions detected on this port.  
CRC/ALIGNMENT ERRORS  
Displays the number of packets with bad Cyclic Redundancy Checks (CRC) that  
have been received from the network. The CRC is a 4-byte field in the data packet  
that ensures that the data received is the same as the data that was originally sent.  
Alignment errors are due to misaligned packets.  
UNDERSIZE PACKETS  
Displays the number of packets received whose size was less than the minimum  
Ethernet frame size of 64 bytes, not including preamble.  
OVERSIZE PACKETS  
Displays the number of packets received whose size exceeded 1518 data bytes,  
not including preamble.  
FRAGMENTS  
Displays the total number of packets received that were not an integral number of  
octets in length or that had a bad Frame Check Sequence (FCS), and were less  
than 64 octets in length (excluding framing bits but including FCS octets).  
JABBERS  
Displays the total number of packets received that were longer than 1518 octets  
(excluding framing bits, but including Frame Check Sequence (FCS) octets), and  
were not an integral number of octets in length or had a bad Frame Check  
Sequence.  
BROADCASTS  
Displays the number of broadcasts received.

9G421-02/9G429-02 Module Specific Information  
MULTICASTS  
Displays the number of multicasts received.  
LINK STATUS  
Indicates whether there is a physical connection from this port to another device.  
One of the following values appears:  
•
Link - There is a link signal present; there is a valid physical connection from  
this port to another device.  
•
No Link - There is no link signal present; there is no valid physical connection  
from this port to another device.  
PORT TYPE  
Displays the value GPIM-F01, which is an Ethernet Gigabit Fiber Channel 1 Gig,  
MMF, SC.  
PORT STATUS  
Indicates the administrative status of the selected port. Possible values are:  
•
•
ENABLED - The port is turned on administratively.  
DISABLED - The port is turned off administratively.  
NOTE  
Enable or disable ports from the Bridge Configuration Screen.  
APPLICATION  
Displays BRIDGING, indicating that the port is operating as a bridge with a  
high-speed backbone connection.  
OPERATION MODE  
Displays the value FULL DUPLEX. The port can transmit and receive data at the  
same time, therefore, the port is running at 1000 Mbps.  
PORT # (Modifiable)  
Selects the port for which statistics are to be displayed.
