Configuring Tracking and Failure Detection Chapter 7 Configuring Redundant ACE Appliances Configuring a Priority on the Active Member for Multiple Probes You can assign a tracking priority that the active member uses when multiple tracking probes are defined. To assign a priority for multiple probes on the active member, use the priority command in FT track host configuration mode. The syntax of this command is: priority number The number argument specifies the priority of the probes 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 gateway or host that the probes are tracking. If all the probes go down, the ACE decrements the priority of the FT group on the active member by the value of the number argument. If the resulting priority of the FT group on the active member is less than the priority of the FT group on the standby member, a switchover occurs. For example, enter: host1/Admin(config-ft-track-host)# priority 50 To reset the priority to the default value of 0, enter: host1/Admin(config-ft-track-host)# no priority 50 Configuring the Gateway or Host IP Address Tracked by the Standby Member To allow the standby member to track a gateway or host, you need to configure the IP address of the gateway or host. To configure the IP address, use the peer track-host command in FT track host configuration mode. The syntax of this command is: peer track-host ip_address The ip_address argument specifies the IP address of the gateway or host that you want the standby FT group member to track. Enter the IP address in dotted-decimal notation (for example, 172.16.27.1). For example, to track the gateway located at 172.16.27.1, enter: host1/Admin(config-ft-track-host)# peer track-host 172.16.27.1 7-32 Cisco 4700 Series Application Control Engine Appliance Administration Guide OL-11157-01
