Installation guide

A Sample VLAN Topology

Chapter 7

clia setlanconfig 1 12 192.168.0.43

This command sets the gateway address of the active and backup ShMMs for eth0.

NOTE In the sample network topology, the default gateway of the ShMM must be set to the

IP address of one of the Ethernet Switch Blades in the vlan4 subnet. Configuration

of vlan4 is covered in the Ethernet Switch Blade configuration section found later in

this document.

Step 2. To check your work, enter the following ShMM command:

clia fruinfo -v 20 1 | more

This command displays the contents of the persistent ShMM settings as held in the chassis

non-volatile FRU (field replaceable unit) memory. You will see the LAN configuration, as you have

entered it in the previous commands.

NOTE Another way to check your work is to issue the following UNIX command:

ifconfig eth0

• On the active ShMM, the IP address should be reported as: 192.168.0.2

• On the backup ShMM, the IP address should be reported as: 192.168.0.3

Configuring eth1

Now that eth0 is configured, you need to set up eth1. Note that eth1 is not configured in the default ShMM

configuration, and must be set up so that each switch can talk directly to its opposite side ShMM. This is done

by adding one ifconfig command in the rc startup file /etc/rc.acb4.

Step 1. Add the following text to the /etc/rc.acb4 file prior to Step 4, highlighted as shown:

# Configure ShMM eth1 interface for cross-connecting to

# the opposite-side switch.

ifconfig eth1 192.168.2.2 netmask 255.255.255.0 up

########

# Step 4: Start up daemons

########

IMPORTANT Ensure this configuration change is added to each ShMM.
