Cisco Systems 3560X Manual De Usuario

If one of the situations in 

 occurs, this message appears:

%FHRP group not consistent with already configured groups on the switch stack - virtual 

MAC reservation failed

From privileged EXEC mode, use this command to display HSRP settings:

 [interface-id [group]] [brief] [detail]

You can display HSRP information for the whole switch, for a specific interface, for an HSRP group, or 
for an HSRP group on an interface. You can also specify whether to display a concise overview of HSRP 
information or detailed HSRP information. The default display is detail. If there are a large number of 
HSRP groups, using the show standby command without qualifiers can result in an unwieldy display.

This is a an example of output from the show standby privileged EXEC command, displaying HSRP 
information for two standby groups (group 1 and group 100):
