Chapter 40 Configuring HSRP
Displaying HSRP Configurations
This example shows how to configure
word
as the authentication string required to allow Hot Standby
routers in group 1 to interoperate:
Switch#
configure terminal
Switch(config)#
interface gigabitethernet1/0/1
Switch(config-if)#
no switchport
Switch(config-if)#
standby 1 authentication word
Switch(config-if)#
end
This example shows how to set the timers on standby group 1 with the time between hello packets at 5
seconds and the time after which a router is considered down to be 15 seconds:
Switch#
configure terminal
Switch(config)#
interface gigabitethernet1/0/1
Switch(config-if)#
no switchport
Switch(config-if)#
standby 1 ip
Switch(config-if)#
standby 1 timers 5 15
Switch(config-if)#
end
Enabling HSRP Support for ICMP Redirect Messages
ICMP redirect messages are automatically enabled on interfaces configured with HSRP. ICMP is a
network layer Internet protocol that provides message packets to report errors and other information
relevant to IP processing. ICMP provides diagnostic functions, such as sending and directing error packets
to the host. This feature filters outgoing ICMP redirect messages through HSRP, in which the next hop
IP address might be changed to an HSRP virtual IP address. For more information, see the
Cisco IOS IP
Configuration Guide, Release 12.2
.
Displaying HSRP Configurations
From privileged EXEC mode, use this command to display HSRP settings:
show standby
[
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.
