Figure 2: IntraServer Technology ITI-5100G Gigibit Ethernet Copper  
10/100/100Base-T Interface Adapter  
The ITI-5100G adapter connects your PCI compliant server or workstation to  
a Gigabit Ethernet network. The adapter incorporates a technology that  
transfers data at a rate of one gigabit per second, 10 times the rate of a Fast  
Ethernet adapter. ITI-5100G offers a Twisted Pair Copper interface, which is  
compatible with existing building (CAT-5) wiring systems. AutoSense speed  
selection allows operation at speeds of 10, 100 and 1000Mbits/sec, making  
the ITI-5100G ideal for upgrading existing networks to Gigabit Ethernet.  
The ITI-5100G/GF adapter targets the increased congestion experienced at  
the backbone and server by today's networks, while providing a future  
upgrade path for high-end workstations that require more bandwidth than  
Fast Ethernet can provide.  
Included with your adapter is the following:  
= Anti-static bag (used for protecting the adapter when stored  
or shipped). Keep the adapter in its packaging until ready for  
installation.  
= ITI-5100G/GF Gigibit Ethernet Adapter Software

Features  
Following is a list of the Gigabit Ethernet PCI adapter features:  
ITI-5100G and GF Models  
= Full-duplex Gigabit Ethernet interface (IEEE P802.3-1999)  
= Jumbo Frame support (optional 9,000 byte frames for server-  
to-server traffic)  
= Standard Ethernet frame size (up to 1518 bytes)  
= Dual Homing for automatic failover if a port, switch, or  
adapter is down  
= VLANs: up to 64 VLANs per adapter using IEEE 802.1Q-  
1998 tagging  
= Adaptive interrupt frequency (maximizes network  
throughput; adapts to traffic load)  
= Dual DMA channels  
= 33/66 MHz, 32-bit or 64-bit PCI bus master with adaptive  
DMA  
= Universal dual voltage signaling (3.3V and 5V)  
= PCI Local Bus Rev 2.1 compliant (6.8"x 4.2")  
= ASIC with on-chip MAC and dual RISC processors  
= Status LEDs  
ITI-5100G Model  
= CAT-5 compatible twisted pair Ethernet Connector  
= Interoperability with existing Ethernet and Fast Ethernet  
Equipment  
ITI-5100GF Model  
= Duplex SC fiber-optic connector  
Key Protocols and Interfaces  
ITI-5100G/GF adapters are interoperable with existing Ethernet equipment  
assuming standard Ethernet minimum and maximum frame size (64 to 1518

bytes), frame format, and compliance with the following standards and  
protocols:  
= Logical Link Control (IEEE 802.2)  
= Flow Control (IEEE 802.3x)  
= SNMP  
= Gigabit Ethernet (IEEE P802.3z)  
VLANs Support  
Virtual Local Area Networks ( VLANs ) are commonly used to split up  
groups of network users into manageable broadcast domains, to create logical  
segmentation of workgroups, and to enforce security policies among logical  
segments.  
Each ITI-5100G/GF adapter supports up to 64 VLANs. With multiple  
VLANs on an adapter, a server with a single adapter can have a logical  
presence on multiple IP subnets.  
Refer to the “Optional Configuration,” section of this manual for  
configuration information.  
Jumbo Frames Support  
To reduce host frame processing overhead, the ITI-5100G/GF adapter and  
Gigabit switches that support jumbo frames, can receive and transmit frames  
that are larger than the maximum frame size allowed on normal Ethernet.  
Dual Homing  
Server switching networks require the capability to employ resiliency and  
redundancy similar to FDDI network environments. ITI-5100G/GF adapters  
provide the Ethernet user with this capability.  
For dual homing support, you must install two ITI-5100G/GFs in the same  
host system. The adapters are configured to provide a hot-standby failover  
service. The switches must be configured to support Spanning Tree on both  
Gigabit Ethernet ports to support the ITI-5100G/GF Dual Homing capability.  
Adaptive Interrupt Frequency  
The adapter driver intelligently adjusts host interrupt frequency based on  
traffic conditions, in order to increase overall application throughput. In light  
traffic, the adapter driver interrupts the host for each received packet,  
minimizing latency. When traffic is heavy, the adapter issues one host

interrupt for multiple, back-to-back incoming packets, preserving host CPU  
cycles.  
Dual DMA Channels  
The PCI interface on the ITI-5100G/GF adapter contains two independent  
DMA channels for simultaneous read and write operations.  
ASIC with Embedded RISC Processor  
The core control for the ITI-5100G/GF adapter resides in a tightly integrated,  
high-performance ASIC. The ASIC includes dual RISC processors. This  
provides the flexibility to add new features to the card and adapt it to future  
network requirements via software download. This also enables the adapter  
drivers to exploit the built-in host off-load functions on the adapter as host  
operating systems are enhanced to take advantage of these functions.  
Diagnostic Support  
An ITI-5100G/GF adapter RISC CPU runs on-board diagnostics at power-up.  
Physical Description  
Figure 3: ITI-5100GF adapter faceplate  
The faceplate of the ITI-5100GF adapter has one 1000Base-SX fiber-optic

Safety Precautions  
CAUTION:  
= The adapter is being installed in a server that operates with  
voltages that can be lethal. Before you remove the cover of your  
server, you must observe the following precautions to protect  
yourself and to prevent damage to the system components.  
= Remove any metallic objects or jewelry from your hands and  
wrists.  
= Make sure to use only insulated or non-conducting tools.  
= Installation or removal of adapters must be performed in a  
static-free environment. The use of a properly grounded wrist  
strap or other personal anti-static devices and an anti-static  
mat is strongly recommended.  
= Verify that the server is powered OFF before accessing internal  
components.  
Pre-Installation Checklist  
1. Check that your server meets the hardware and software requirements  
listed in Table 5: Hardware and Software Requirements.  
2. Review the information in the readme file on the ITI-5100G/GF  
Software Distribution media for important information not available at  
the time this manual was printed.  
Note: If you acquired the adapter software on a floppy disk or from the  
IntraServer Technology support website, please check the appropriate  
source for the most recent information.  
3. If your system is active, execute proper shutdown.  
4. When system shutdown is complete, power OFF your system.  
5. Holding the adapter card by the edges, remove it from its shipping  
package it and place it on an anti-static surface.  
6. Check the adapter for visible signs of damage, particularly on the card's  
edge connector. Never attempt to install any damaged adapter.  
If the adapter is damaged, report it to your IntraServer Technology  
Customer Support Representative. For more information, see Contacting  
IntraServer Technology.

PCI Adapter Installation  
To install a PCI ITI-5100G/GF adapter in your system, perform the following  
procedure.  
1. Observe all precautions and pre-installation instructions in the Safety  
Precautions section.  
Before installing the adapter, ensure the system power is OFF , and  
proper electrical grounding procedures have been followed.  
2. Remove the server cover, and select any empty PCI slot.  
If you do not know how to identify a PCI slot, refer to your server  
documentation.  
3. Remove the blank cover-plate from the slot that you selected. Retain the  
screw so that it can be replaced later.  
4. Holding the PCI card by the edges, align the adapter's connector edge  
with the PCI connector dock in the server.  
Note: The connector dock in a 32-bit PCI slot is shorter than in a 64-  
bit PCI slot. Although the adapter is designed to fit in either slot type,  
when installed in a 32-bit PCI slot, part of the adapter's connector  
edge will remain undocked. This is perfectly normal.  
5. Applying even pressure at both corners of the card, push the adapter  
card until it is firmly seated in the PCI slot.  
CAUTION: Do not use excessive force when seating the card,  
as this may damage the server or the adapter. If the card  
resists seating, remove it from the system, realign it, and try  
again.  
When properly seated, the adapter's port connectors will be aligned with  
the slot opening, and its faceplate will be flush against the server  
chassis.  
6. Use the screw removed above (in Step 3) to secure the adapter in the  
PCI card cage.  
7. Replace the server cover and disconnect any personal anti-static devices.  
8. Power the server on.  
Once the server returns to proper operation, the adapter hardware is fully  
installed. You must next connect the network cables (see Connecting the  
Network Cables) and install the adapter driver software (see Installing  
the Driver Software).

Note: The ITI-5100G/GF adapter must be physically installed in your  
server prior to installing the driver software. See “Installing the ITI-  
5100G-GF Hardware,” for details.  
To install the adapter software for Solaris, perform the following procedure:  
1.  
2.  
Become superuser (root).  
Note the revision level of the Software Distribution Media included  
with your IntraServer Technology adapter.  
The revision level is stamped on the Software Distribution Media  
label and is used in the commands below.  
Place the Software Distribution Media into the CD-ROM drive.  
Mount the CD-ROM on a local directory.  
ꢀꢁ If the Volume manager (vold) is running on your machine, when the  
ITI-5100G/GF CD-ROM is loaded into the drive, it is mounted  
automatically under /cdrom/cdrom0

If the appropriate ITI-5100G/GF device is not listed, check that the adapter is  
installed and properly seated. Then restart the system and re-install the  
adapter software.  
Configuring the Host Files  
Once the ITI-5100G/GF adapter software is installed on your system, it must  
be configured. To ensure proper adapter performance, configure the host files  
and driver parameters as described in the following sections.  
LSI Logic Corporation  
Page 25 of 56  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Note: If any adapter card is moved from one slot to another, the alt  
instance values in the /etc/path_to_inst file will be incorrect.  
Correct the instance values before making any adapter configuration  
changes. See your Solaris manuals for details on setting instance values.  
= Each adapter must be assigned a host name and an IP  
address. If you are not using multiple VLANs, perform the  
steps below when configuring the host name and IP address  
for your adapter.  
= If VLANs are to be used, any specific adapter may have one  
host name and IP address for each VLAN. If you will be  
using VLANs on the network, see the Configuring VLANs  
section of this manual.  
1. Create the /etc/hostname.alt <num> file(s) on the server.  
There can be up to four adapters per server. Create one  
/etc/hostname.alt <num> file for each adapter. The number  
<num> in the filename is determined as follows:  
Hostname Numbering  
Adapter  
First  
Second  
Third  
Hostname  
/etc/hostname.alt0  
/etc/hostname.alt1  
/etc/hostname.alt2  
/etc/hostname.alt3  
Fourth  
For example, the first adapter in the server requires a file named  
/etc/hostname.alt0 and the second adapter requires a file  
named /etc/hostname.alt1 .  
2. Place the appropriate adapter host name into the hostname.alt  
<num> file(s).  
The /etc/hostname.alt <num> file must contain the appropriate  
host name for the adapter. The host name should be different from that  
of any other interface. For example, /etc/hostname.alt0 and  
/etc/hostname.alt1 cannot share the same host name.  
The following example depicts the host name files required for a  
machine called iti , with ITI-5100G/GF adapters known as iti-1 ,  
iti-2 , iti-3 , and iti-4 on the networks created for alt0 , alt1  
, alt2 , and alt3 .

iti-1  
iti # cat /etc/hostname.alt1  
iti-2  
iti # cat /etc/hostname.alt2  
iti-3  
iti # cat /etc/hostname.alt3  
iti-4  
3. For each host name, enter the appropriate IP address in the  
/etc/hosts file.  
4. Reboot the system.  
If you make changes and put the system into service before rebooting, you  
may experience configuration problems.  
Perform this command to reboot the system:  
# reboot -- -r  
Configuring Driver Parameters  
with ndd  
The ndd (1M) utility is useful for changing configuration parameters for the  
adapter. Alternately, adapter parameters can be changed by manually editing  
the configuration files. This section describes the ndd utility in detail.  
Note: Any changes made with ndd are temporary and will be lost when  
you reboot the system. To make configuration changes survive the reboot  
process, you will need to store driver settings in the  
/etc/rc2.d/S99itialt file (see Saving Driver Parameters Beyond  
Reboot).  
Available Parameters  
To view parameters that you can set using the ndd command, type:  
# ndd /dev/alt '?'

Table 8: Adapter Driver Parameters  
Checking Parameter Settings  
To check a current parameter setting, use the following command:  
# ndd /dev/alt <parameter_name>  
Setting Parameters  
Follow this procedure to set parameters using the ndd utility:  
1. Check the /etc/path_to_inst file for the instance  
associated with particular devices.  
2. Specify the instance for the adapter you wish to configure:  
# ndd -set /dev/alt instance <instance#>  
Any subsequent ndd configuration commands will act on the  
adapter with the selected instance. The adapter remains selected  
until you specify a different instance.  
3. Specify the configuration command using the following format:  
# ndd -set /dev/alt <parameter> <value>  
A list of valid parameters and values can be found in Available Parameters.

Note: Any changes made with ndd will be lost when you reboot the system.  
To make configuration changes survive reboot, store driver settings in the  
/etc/rc2.d/S99itialt file (see Saving Driver Parameters Beyond  
Reboot).  
Link Negotiation  
The default configuration for link negotiation of the Gigabit Ethernet link is  
auto . With this setting the ITI-5100G/GF adapter will use IEEE 802.3-  
1998 auto negotiation.  
If you are connecting the adapter to Gigabit Ethernet equipment that does not  
support auto negotiation, or if there is a problem establishing a link between  
the two devices, auto negotiation can be turned off (see Available  
Parameters).  
Increasing TCP/IP Performance  
The TCP/IP performance of the ITI-5100G/GF PCI adapter can be increased  
by changing the TCP/IP ndd values. This can be done with the ndd (1M)  
utility, as described below.  
Enter the following ndd commands to increase TCP/IP performance:  
# ndd -set /dev/tcp tcp_recv_hiwat 65535  
# ndd -set /dev/tcp tcp_xmit_hiwat 65535  
# ndd -set /dev/udp udp_recv_hiwat 65535  
# ndd -set /dev/udp udp_xmit_hiwat 65535  
To avoid losing these settings when reboot occurs, add your ndd parameter  
settings to the start-up file as described in the following section, Saving  
Driver Parameters Beyond Reboot.

Optional Configuration  
Your IntraServer Technology ITI-5100G/GF adapter can be configured to  
support the following options:  
= VLANs: Virtual Local Area Networks (VLANs) are  
commonly used to split up groups of network users into  
manageable broadcast domains, to create logical  
segmentation of workgroups, and to enforce security policies  
among each logical segment. Up to 64 VLANs can be  
defined for each ITI-5100G/GF adapter on your server  
= Jumbo Frames: Standard Ethernet frames are 1,500 bytes  
long. When sending Ethernet traffic at Gigabit speeds, a  
considerable portion of the bandwidth is consumed by the  
overhead of handling a multitude of small packets. ITI-  
5100G/GF adapters support Ethernet frames of 9,000 bytes.  
Host CPU utilization is significantly reduced and network  
throughput is enhanced when enabling Jumbo Frames  
between servers that have ITI-5100G/GF adapters and  
switches that support Jumbo Frames.  
= Dual Homing: Two ITI-5100G/GF adapters on a server can  
be paired for redundant operation through the use of the  
Dual Homing feature. If traffic on a primary connection is  
lost due to the failure of the adapter, cable, switch port, or  
switch (when the dual adapters are attached to separate  
switches), the secondary adapter becomes active and  
assumes the MAC and IP address of the primary adapter.  
Network sessions should be maintained after the switchover,  
causing minimum impact to network traffic.  
This chapter describes these options in detail, with configuration instructions  
and examples. If your network does not require VLANs, Jumbo Frames, or  
Dual Homing, you need only configure the adapter to support the default  
configuration, as described in “The ITI-5100G/GF Driver Software”.

Note: If you modify any of the optional configuration parameters (VLANs,  
Jumbo Frame, or Dual Homing), you must reboot the system before the  
changes will take effect. If you make changes and do not reboot, you may  
experience configuration problems.

VLANs  
VLANs allow you to split your physical LAN into logical subparts, providing  
an essential tool for increasing the efficiency and flexibility of your network.  
Overview  
Each defined VLAN behaves as its own separate network, with its traffic and  
broadcasts isolated from the other VLANs to increase bandwidth efficiency  
within each logical group. One example of how VLANs can be used to  
segment a LAN is when isolating different types of network traffic. If you  
wanted to utilize Jumbo Frames on a portion of your LAN, you could  
configure one VLAN for devices that support Jumbo Frames, and a separate  
VLAN for devices supporting only standard frames. By implementing  
VLANs, you could segregate the different frame types from each other  
without reorganizing your LAN into separate physical subnets.  
Although VLANs are commonly used to create individual broadcast domains  
and/or separate IP subnets, it is sometimes useful for a server to have a  
presence on more than one VLAN simultaneously. Alteon WebSystems  
switches and ITI5100G/GF adapters support multiple VLANs on a per-port  
or per-interface basis, allowing very flexible network configurations.  
See Figure 6 for an example of servers supporting multiple VLANs with  
Tagging.

In the example network shown in Figure 6, the physical LAN consists of a  
switch, two servers, and five clients. The LAN is logically organized into  
three different VLANs, each representing a different IP subnet. The features  
of this network are described in the following table.  
Example VLAN Network Topology  
Component Description  
An IP subnet consisting of the Main Server, PC #3, and PC #5.  
This subnet represents an engineering group.  
VLAN #1  
Includes the Main Server, PCs #1 and #2 via shared media  
VLAN #2  
VLAN #3  
segment, and PC #5. This VLAN is a software development  
group.  
Includes the Main Server, the Accounting Server and PC #4.  
This VLAN is an accounting group.  
A high-use server that needs to be accessed from all VLANs  
and IP subnets. The Main Server has an ITI5100G adapter  
installed. All three IP subnets are accessed via the single  
physical adapter interface. The server is attached to an Alteon  
WebSystems switch Gigabit Ethernet port, which is  
Main Server configured for VLANs #1, #2, and #3. Both the adapter and  
the connected switch port have tagging turned on. Because of  
the tagging VLAN capabilities of both devices, the server is  
able to communicate on all three IP subnets in this network,  
but continues to maintain broadcast separation between all of  
them.  
Available to VLAN #3 only. The Accounting Server is  
isolated from all traffic on VLANs #1 and #2. The switch port  
connected to the server has tagging turned off.  
Accounting  
Server  
Attached to a shared media hub that is then connected to the  
switch. PCs #1 and #2 belong to VLAN #2 only, and are  
PCs #1 and #2 logically in the same IP subnet as the Main Server and PC #5.  
The switch port connected to this segment has tagging turned  
off.  
A member of VLAN #1, PC #3 can communicate only with  
PC #3  
PC #4  
the Main Server and PC #5. Tagging is not enabled on PC  
#3's switch port.  
A member of VLAN #3, PC #4 can only communicate with  
the servers. Tagging is not enabled on PC #4's switch port.  
A member of both VLANs #1 and #2, PC #5 has an ITI5100G  
adapter installed. It is connected to switch port #10. Both the  
adapter and the switch port are configured for VLANs #1 and  
#2 and have tagging enabled.  
PC #5  
Table 9: Example VLAN Network Topology  
LSI Logic Corporation  
Page 36 of 56

VLAN tagging is only required to be enabled on switch ports that  
create trunk links to other VLAN capable switches, or on ports  
connected to tag-capable end-stations, such as servers or workstations  
with ITI5100G/GF adapters.  
Configuring VLANs  
By default, Alteon WebSystems switches have a single VLAN configured for  
every port, which groups all ports into the same broadcast domain, just as if  
there were no VLANs at all. This default VLAN has an 802.1Q-1998 VLAN  
identification number of [1], with VLAN tagging for the switch port turned  
off.  
If you are using a VLAN capable switch from another manufacturer, consult  
the documentation for your switch before continuing.  
To configure VLANs, perform the following procedure:  
Note: If you configure a VLAN for an adapter, all traffic sent or received  
by that adapter must be in VLANs.  
1. Create the /etc/hostname.alt file(s) on the server.  
There can be up to four adapters per server, and up to 64 VLANs  
defined per adapter.  
One /etc/hostname.alt <num> file must be created for each  
VLAN that will be configured for each adapter on the server. Create  
files using the following naming format:  
/etc/hostname.alt <num>  
For each file, the number <num> in the filename is determined according  
to the table below. For example, the first adapter in the server requires a  
file named /etc/hostname.alt0 for its first VLAN, and a file  
named /etc/hostname.alt100 for its second VLAN.  
Up to 64

Table 10: Creating the /etc/hostname.alt<num> files  
2. Place the appropriate adapter host name into the  
/etc/hostname.alt file(s).  
The /etc/hostname.alt <num> file must contain the appropriate  
adapter host name.  
The host name should be different from the host name of any other  
interface. For example, /etc/hostname.alt0 and  
/etc/hostname.alt100 cannot share the same host name.  
The following example depicts the host name files required for a  
machine called iti , with one ITI5100G/GF adapter with four VLANs:  
iti # cat /etc/hostname.alt0  
iti-1  
iti # cat /etc/hostname.alt100  
iti-1100  
iti # cat /etc/hostname.alt200  
iti-1200  
iti # cat /etc/hostname.alt300  
iti-1300  
3. For each host name, enter the appropriate IP address in the  
/etc/hosts file.  
4. Create the /etc/vlan.alt <num> file(s).  
One corresponding /etc/vlan.alt <num> file is needed for each  
/etc/hostname.alt <num> file created in the previous steps (one  
for each VLAN being configured for each adapter on the server). Create  
files using the following naming format:  
/etc/vlan.alt <num>  
For each file, the number <num> in the filename is determined according  
to the table below. For example, the first adapter requires a file named  
/etc/vlan.alt0 for its first VLAN, and a file named  
/etc/vlan.alt100 for its second VLAN.

Table 11: Creating the /etc/vlan.alt<num> files  
5. Place the appropriate VLAN ID tag into the vlan.alt <num> file(s).  
Each VLAN must be assigned a unique identification number. Even  
though the maximum number of VLANs that can be configured on each  
adapter is 64, any particular VLAN can be assigned an identification  
number between 1 and 4094. The VLAN tagging format follows the  
guidance provided in IEEE 802.1Q-1998.  
The VLAN identifier numbers must be placed into each appropriate  
vlan.alt <num > file to which the adapter is a member.  
Example: Consider a server with a single adapter. The server is a  
member of two VLANs, with VLAN identifiers 383 and 777. The  
contents of the first file, /etc/vlan.alt0 , would be "383" and the  
contents of the second file, /etc/vlan.alt100 , would be "777".  
Use your regular text editor to put the VLAN identifier number into the  
appropriate vlan.alt <num> file. Be certain that there are no spaces,  
blank lines, or extra characters. The identifier can be entered in decimal  
(e.g. 383), octal (e.g. 0577), or hexadecimal (e.g. 0x17F) format.  
If you are finished with all optional configurations, reboot the system.  
Changes to the optional configuration parameters (VLAN, Jumbo Frame, or  
Dual Homing) do not take effect until you reboot the system. If you will be  
making changes to the other optional parameters during your configuration  
session, you should wait to reboot until those changes are complete.  
If you modify parameters and put the system into service before rebooting,  
you may experience configuration problems.  
Perform this command to reboot the system:

Verify the configuration changes.  
Enter the following command and verify that the appropriate VLANs are  
present:  
# ifconfig -a  
Jumbo Frames Support  
ITI-5100G/GF adapters support Jumbo Frames--frames of up to 9,000 bytes  
that are sent between servers that have ITI-5100G/GF adapters and switches  
that support Jumbo Frames. Host CPU utilization is significantly reduced and  
network throughput is enhanced by sending 9,000 byte frames rather than the  
standard 1,500 byte Ethernet frames.  
Overview  
A single ITI-5100G/GF adapter on a server can support standard Ethernet  
frames as well as Jumbo Frames. Jumbo Frames are only sent between  
servers that have ITI-5100G/GF adapters. Standard Ethernet frames are used  
between servers that have ITI-5100G/GF Adapters and all other Ethernet  
devices.  
Note: Not all network switches support passing Jumbo Frames. Check  
with your switch manufacturer for confirmation of Jumbo Frame support.  
Configuring Jumbo Frames Support  
To configure Jumbo Frame support, perform the following procedure:  
1. Create the /etc/jumbo.alt <num> file.  
2. Use your regular text editor to put the number “9000 " into the  
/etc/jumbo.alt <num> file.  
Put the number “9000 " in the file, without spaces or blank lines.  
3. If you are finished with all optional configuration, reboot the system.  
Changes to the optional configuration parameters (Jumbo Frame, or  
Dual Homing) do not take effect until you reboot the system. If you will  
be making changes to the other optional parameters during your  
configuration session, you should wait to reboot until those changes are  
complete.

Note: If you modify parameters and put the system into service before  
rebooting, you may experience configuration problems.  
Perform this command to reboot the system:  
# reboot  
4. Verify the configuration changes.  
Enter the following command and verify that the MTU size is set to 9000:  
# ifconfig -a  
Dual Homing  
When two ITI-5100G/GF adapters are installed in the same server, they can  
be paired in a Dual Homing configuration. If traffic is not seen over the  
primary adapter connection due to loss of the adapter, cable, switch port, or  
switch (where the two adapters are attached to separate switches), the  
secondary adapter becomes active. When it becomes active, the secondary  
adapter uses the MAC and IP address originally assigned to the primary  
adapter. Sessions should be maintained, with minimum impact to network  
traffic.  
Overview  
The Dual Homing feature relies on the Spanning Tree Protocol. Adapters  
configured for Dual Homing allow Spanning Tree Protocol packets to pass  
between them. This causes the Spanning Tree Protocol to detect a loop in the  
network, forcing the switch port connected to one of the adapters to go into  
blocking mode. The blocked adapter becomes the secondary.  
Primary Connection Failed  
Both Connections Ready  
Loop Resolved:  
Spanning Tree Loop Detected:  
ACEnic #1 has dropped from service  
ACEnic #1 is active  
ACEnic #2 is active  
ACEnic #2 is blocked at switch port  
Figure 7: Dual Homing with Spanning Tree  
If the primary connection becomes disabled for any reason, the Spanning  
Tree Protocol will detect the loss of the loop, and will change the switch port  
connecting the secondary adapter from blocking mode to forwarding mode.

Configuring Dual Homing  
To configure Dual Homing in a system with two adapters, where  
/etc/hostname.alt0 is the primary adapter, perform the following  
procedure:  
Note: Do not configure an /etc/hostname.alt<num> entry for the  
redundant adapter. Also, do not configure Jumbo Frame support files for  
the redundant adapter. If the primary adapter fails, the secondary adapter  
takes on the configuration of the primary adapter. Serious configuration  
problems will occur if there are hostname or Jumbo Frame configuration files  
for the secondary adapter.  
1. Enable Spanning Tree Protocol on the switch connected to your ITI-  
5100G/GF adapters.  
2. The port to which the secondary adapter is connected must be the port  
that blocks.  
If there is more than one switch in the spanning tree, be certain that the  
secondary adapter is not attached to the root switch of the spanning tree.  
Also, be sure that the port path cost of the switch port connected to the  
secondary adapter is higher than the other ports in the loop.  
Example: In the following redundant switch configuration, the switch  
port connected to adapter #2 must have the highest port path cost of any  
of the four ports in the loop:  
Switch port to active  
adapter needs lower  
Inter-switch path is required  
path cost  
for loop condition. Loop  
ports need lower path cost  
Switch port to secondary  
adapter must have highest  
path cost to block  
Figure 8: Dual Homing Path Costs  
3. Create the /etc/redund.alt1 file.  
4. Use your regular text editor to put the number " 0 ", the instance  
number of the primary adapter, into the file /etc/redund.alt1 .  
Put the number " 0 " in the file, without spaces or blank lines.  
5. If you are finished with all optional configuration, reboot the system.

Changes to the optional configuration parameters (Jumbo Frame, or Dual  
Homing) do not take effect until you reboot the system. If you will be making  
changes to the other optional parameters during your configuration session,  
you should wait to reboot until those changes are complete.  
Note: If you modify parameters and put the system into service before  
rebooting, you may experience configuration problems.  
Perform this command to reboot the system:

Network Cabling Requirements  
In order for your network to operate properly, you must use a category of  
network cabling that is appropriate for the data rate of the channel. For  
10Mb/s operation, Category 3, or 5 cable is appropriate. When operating in  
100/1000Mb/s or 100/1000Mb/s Full Duplex, a Category 5 cable should be  
used.  
The maximum cable segment length supported at 100/1000Mb/sec speed, on  
Category 5 cable is 100M. Any single cable segment (adapter to adapter or  
adapter to network hub) must be within the 100M length requirement.
