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
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
