Cisco Systems OL-7029-01 manual Standby track, Decrement priority, Back up

Chapter 3 Commands Specific to the Content Switching Module with SSL

standby track

standby track

To configure HSRP to track an object and change the hot standby priority based on the state of the object, use the standby track command. Use the no form of this command to remove the tracking.

standby [group-number]track object-number [decrement priority]

no standby [group-number]track object-number [decrement priority]

Syntax Description	group-number		(Optional) Group number to which the tracking applies.
	object-number		Object number in the range from 1 to 500 representing the object to be
			tracked.
	decrement priority		(Optional) Amount by which the hot standby priority for the router is
			decremented (or incremented) when the tracked object goes down (or comes
			back up).
Defaults	The defaults are as follows:
	•	group-number is 0.
	•	priority is 10.
Command Modes	Proxy-VLAN configuration submode
Command History	Release		Modification
	SSL Services Module		Support for this command was introduced on the Catalyst 6500 series
	Release 2.1(1)		switches.
	CSM-S release 1.1(1) This command was introduced.
Usage Guidelines	This command ties the hot standby priority of the router to the availability of its tracked objects. Use the
	track interface or track ip route global configuration command to track an interface object or an IP
	route object. The HSRP client can register its interest in the tracking process by using the standby track
	command commands and take action when the object changes.

When a tracked object goes down, the priority decreases by 10. If an object is not tracked, its state changes do not affect the priority. For each object configured for hot standby, you can configure a separate list of objects to be tracked.

The optional priority argument specifies how much to decrement the hot standby priority when a tracked object goes down. When the tracked object comes back up, the priority is incremented by the same amount.

When multiple tracked objects are down, the decrements are cumulative, whether configured with priority values or not.

Use the no standby group-numbertrack command to delete all tracking configuration for a group.
