Chapter 44 Configuring HSRP
Displaying HSRP Configurations
Troubleshooting HSRP for Mixed Stacks of Catalyst 3750-X, 3750-E and 3750
Switches
If one of the situations in Table 44-2 occurs, this message appears:
%FHRP group not consistent with already configured groups on the switch stack - virtual
MAC reservation failed
Displaying HSRP Configurations
From privileged EXEC mode, use this command to display HSRP settings:
show standby [int
erface-id [group]] [brief] [detail]
You can display HSRP information for the whole sw
itch, 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 sho
w standby privileged EXEC command, displaying HSRP
information for two standby groups (group 1 and group 100):
Switch# show standby
VLAN1 - Group 1
Local state is Standby, priority 105, may preempt
Hellotime 3 holdtime 10
Next hello sent in 00:00:02.182
