This example shows how to configure HSRP object tracking on Ethernet 1/2:
switch# configure terminal
switch(config)# track 1 interface ethernet 2/2 line-protocol
switch(config)# interface ethernet 1/2
switch(config-if)# no switchport
switch(config-if)# hsrp 2
switch(config-if-hsrp)# track 1 decrement 20
switch(config-if-hsrp)# copy running-config startup-config

Configuring the HSRP Priority

You can configure the HSRP priority on an interface. HSRP uses the priority to determine which HSRP
group member acts as the active router.
To configure the HSRP priority, use the following command in interface configuration mode:
Command
priority level [forwarding-threshold lower
lower-value upper upper-value ]
Example:
switch(config-if-hsrp)# priority 60
forwarding-threshold lower 40 upper 50
Customizing HSRP
You can optionally customize the behavior of HSRP. Be aware that as soon as you enable an HSRP group
by configuring a virtual IP address, that group is now operational. If you first enable an HSRP group
before customizing HSRP, the router could take control over the group and become the active router
before you finish customizing the feature. If you plan to customize HSRP, you should do so before you
enable the HSRP group.
