Chapter 7 Configuring Redundant ACE Appliances Configuring Tracking and Failure Detection Configuring the Interface Tracked by the Standby Member To configure the interface that you want the standby member to track, use the peer track-interface vlan command in FT track interface configuration mode. The syntax of this command is: peer track-interface vlan vlan_id For the vlan_id argument, enter the VLAN ID of an existing VLAN configured on the standby member as an integer from 2 to 4094. For example, to track the critical interface VLAN 200, enter: host1/Admin(config-ft-track-intf)# peer track-interface vlan 200 To remove VLAN 200 from the tracking process, enter: host1/Admin(config-ft-track-intf)# no peer track-interface vlan 200 Configuring a Priority for a Tracked Interface on the Standby Member To assign a priority to the tracked interface that the standby member is tracking, use the peer priority command in FT track interface configuration mode. The syntax of this command is: peer priority number The number argument specifies the priority of the interface on the standby 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 standby 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)# peer priority 25 To reset the interface priority on the standby member to the default value of 0, enter: host1/Admin(config-ft-track-intf)# no peer priority 25 OL-11157-01 Cisco 4700 Series Application Control Engine Appliance Administration Guide 7-37

Chapter 7
Configuring Redundant ACE Appliances
Configuring Tracking and Failure Detection
Configuring the Interface Tracked by the Standby Member
To configure the interface that you want the standby member to track, use the
peer
track-interface vlan
command in FT track interface configuration mode. The
syntax of this command is:
peer track-interface vlan
vlan_id
For the
vlan_id
argument, enter the VLAN ID of an existing VLAN configured on
the standby member as an integer from 2 to 4094.
For example, to track the critical interface VLAN 200, enter:
host1/Admin(config-ft-track-intf)#
peer track-interface vlan 200
To remove VLAN 200 from the tracking process, enter:
host1/Admin(config-ft-track-intf)#
no peer track-interface vlan 200
Configuring a Priority for a Tracked Interface on the Standby Member
To assign a priority to the tracked interface that the standby member is tracking,
use the
peer priority
command in FT track interface configuration mode. The
syntax of this command is:
peer priority
number
The
number
argument specifies the priority of the interface on the standby
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 standby 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)#
peer priority 25
To reset the interface priority on the standby member to the default value of 0,
enter:
host1/Admin(config-ft-track-intf)#
no peer priority 25
