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.
1 Create a default VLAN for the HA VLAN ports with the vlan command as shown below:
-> vlan 10
2 Assign 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
3 Create a VLAN that will become the HA VLAN once configured with ingress and egress ports. For
example:
-> vlan 200
4 Configure 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
5 Configure 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
6 Assign 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
7 Configure 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.
8 Set 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
