Configuring the Interface Tracked by the Active Member
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
Configuring a Priority for a Tracked Interface on the Active Member
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
