Configuring High Availability VLANs
Release 5.1.6.R02 User Guide Supplement June 2005 page 3-3
Quick Steps for Creating High Availability VLANs
Follow the steps below for a quick tutorial on configuring high availability (HA) VLANs. Additional
information on how to configure each command is given in the sections that follow.
1Create a default VLAN for the HA VLAN ports with the vlan command as shown below:
-> vlan 10
2Assign ports to the new default VLAN with the vlan port default command as shown below:
-> vlan 10 port default 1/1, 3/2, 3/7, 6/1, 6/2
3Create a VLAN that will become the HA VLAN once configured with ingress and egress ports. For
example:
-> vlan 200
4Configure ports 1/1 and 3/2 as ingress ports for HA VLAN 200. Use the vlan port-mac ingress-port
command as shown below:
-> vlan 200 port-mac ingress-port 1/1 3/2
5Configure ports 6/1 and 6/2 as egress ports for HA VLAN 200. Use the vlan port-mac egress-port
command as shown below:
-> vlan 200 port-mac egress-port 6/1 6/2
6Assign a MAC address to this high availability VLAN with the mac-address-table port-mac vlan
mac command. For example:
-> mac-address-table port-mac vlan 200 mac 00:DA:29:3C:11:20
7Configure port 3/7 as an inter-switch port for the HA VLAN with the vlan 802.1q command as shown
below:
-> vlan 200 802.1q 3/7
Note that Step 7 is only done when the HA VLAN is configured across two switches. The ports that
provide the connection between the two switches must be tagged with the HA VLAN ID.
8Set the HA VLAN ingress flood queue bandwidth size to 100 Mbps. Use the vlan port-mac band-
width command as shown below:
-> vlan 200 port-mac bandwidth 100
