Configuring Tracking and Failure Detection Chapter 7 Configuring Redundant ACE Appliances 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 7-36 Cisco 4700 Series Application Control Engine Appliance Administration Guide OL-11157-01
