Using the debug Command, 253 | Cisco Systems RJ-45-to-AUX guide

Tip	To get a brief output of all the configured interfaces, you can use the show standby brief
	command.

Using the debug Command

By enabling the debug command, it will list the changes in real−time for the HSRP group you specified. This includes the sending and receiving packets through the HSRP. To enable debugging of your HSRP group you need to use the following command at the Privileged Exec prompt:

debug standby

Warning The debugging feature is automatically assigned a high priority on the CPU, so this command can have a big impact on the internal route processor’s performance.

To disable the debugging feature, enter either the no debug standby or the no debug command.
