Chapter 2 Commands for the Catalyst 6500 Series SSL Services Module

standby track

	When you use group number 0, no group number is written to NVRAM, providing backward
	compatibility.
	The standby track command syntax prior to Release 12.2(15)T is still supported. Using the older form
	will cause a tracked object to be created in the new tracking process. This tracking information can be
	displayed using the show track command.
Examples	This example shows how to track the IP routing capability of serial interface 1/0. HSRP on Ethernet
	interface 0/0 registers with the tracking process to be informed of any changes to the IP routing state of
	serial interface 1/0. If the IP state on Serial interface 1/0 goes down, the priority of the HSRP group is
	reduced by 10.
	If both serial interfaces are operational, Router A becomes the HSRP active router because it has the
	higher priority.
	However, if IP routing on serial interface 1/0 in Router A fails, the HSRP group priority is reduced and
	Router B takes over as the active router, thus maintaining a default virtual gateway service to hosts on
	the 10.1.0.0 subnet.
