To configure the interface that you want the active member to track, use the
track-interface vlan command in FT track interface configuration mode. The
syntax of this command is:
track-interface vlan vlan_id
For the vlan_id argument, enter the VLAN ID of an existing VLAN configured on
the active member as an integer from 2 to 4094.
For example, to track the critical interface VLAN 100, enter:
host1/Admin(config-ft-track-intf)# track-interface vlan 100
To remove VLAN 100 from the tracking process, enter:
host1/Admin(config-ft-track-intf)# no track-interface vlan 100
To assign a priority to the interface that the active member is tracking, use the
priority command in FT track interface configuration mode. The syntax of this
command is:
priority number
The number argument specifies the priority of the interface on the active member.
Enter a priority value as an integer from 0 to 255. The default is 0. Higher values
indicate higher priorities. Assign a priority value based on the relative importance
of the interface that you are tracking. If the tracked interface goes down, the ACE
decrements the priority of the FT group on the active member by the value of the
number argument. If the priority of the FT group on the active member falls below
the priority of the FT group on the standby member, a switchover occurs.
For example, enter:
host1/Admin(config-ft-track-intf)# priority 50
To reset the interface priority on the active member to the default value of 0, enter:
host1/Admin(config-ft-track-intf)# no priority 50
