H Commands

This chapter describes the Cisco NX-OS Hot Standby Router Protocol (HSRP) commands that begin with H.

hsrp

To enter Hot Standby Router Protocol (HSRP) configuration mode and create an HSRP group, use the hsrp command. To disable HSRP, use the no form of this command.

hsrp group-number ipv4

no hsrp group-number ipv4

 
Syntax Description

group-number

Number of HSRP groups that can be configured on a Gigabit Ethernet port, including the main interfaces and subinterfaces. The range is from 1 to 255. The default value is 0.

ipv4

(Optional) Sets the HSRP group for IPv4.

 
Command Default

Disabled

 
Command Modes

Interface configuration mode

 
Command History

Release
Modification

6.0(2)N1(1)

This command was introduced.

 
Usage Guidelines

You must globally enable HSRP before you can configure any HSRP options or create an HSRP group.

Examples

This example shows how to create and activate an HSRP group:

switch# configure terminal
switch(config)# interface ethernet 0
switch(config-if)# no switchport
switch(config-if)# ip address 172.16.6.5 255.255.255.0
switch(config-if)# hsrp 1
switch(config-if-hsrp)#
 

This example shows how to create and activate an HSRP group for IPv6:

switch# configure terminal
switch(config)# interface ethernet 1
switch(config-if)# no switchport
switch(config-if)# ipv6 address 172.16.6.5 255.255.255.0
switch(config-if)# hsrp 1
switch(config-if-hsrp)#

Command
Description

feature hsrp

Enables HSRP configuration.

ip address

Creates a virtual IP address for the HSRP group. The IP address must be in the same subnet as the interface IP address.

show hsrp

Displays HSRP information.

 

hsrp delay

To delay Hot Standbu Router Protocol (HSRP) initialization after a reload or after an interface comes up, use the hsrp delay command. To disable this function, use the no form of this command.

hsrp delay { minimum min-delay | reload reload-delay }

no delay { minimum min-delay | reload reload-delay}

 
Syntax Description

minimum min-delay

Specifies the minimum time (in seconds) to delay HSRP group initialization after an interface comes up. This period applies to all subsequent interface events. The range is from 1 to 10,000. The default is 0 seconds.

reload reload-delay

Specifies the time period to delay HSRP group initialization after the router has reloaded. This period applies only to the first interface-up event after the router has reloaded. The range is from 1 to 10,000. The default is 0 seconds.

 
Command Default

The HSRP delay default is 0 seconds.

 
Command Modes

Interface configuration mode

 
Command History

Modification

6.0(2)N1(1)

This command was introduced.

 
Usage Guidelines

Use the hsrp delay command to delay HSRP initialization either after a reload or after an interface comes up. This configuration allows the interface and router to stabilize after the interface comes up and helps prevent HSRP state flapping.

Examples

This example shows how to configure a minimum delay of 3 seconds and a group initialization delay of 10 seconds:

switch# configure terminal
switch(config)# interface ethernet 1/5
switch(config-if)# no switchport
switch(config-if)# ip address 172.16.6.5 255.255.255.0
switch(config-if)# hsrp 1
switch(config-if-hsrp)# hsrp delay minimum 3 reload 10
switch(config-if-hsrp)#
