V Commands

This chapter describes the Cisco NX-OS Virtual Router Redundancy Protocol (VRRP) commands that begin with V.

vrrp

To create a Virtual Router Redundancy Protocol (VRRP) group on a particular Ethernet interface and assign a number to the VRRP group and enter VRRP configuration mode, use the vrrp command. To remove a VRRP group, use the no form of this command.

vrrp number

no vrrp number

Syntax Description

number

VRRP group number, which you can configure for a Gigabit Ethernet port, including the main interfaces and subinterfaces. The range is from 1 to 255.

Command Default

None

Command Modes

Interface configuration mode

Command History

Release	Modified
6.0(2)N1(1)	This command was introduced.

Usage Guidelines

You can configure VRRP only if its state is disabled. Make sure that you configure at least one IP address before you attempt to enable a virtual router.

Examples

This example shows how to create a VRRP group:

switch# configure terminal

switch(config)# interface ethernet 2/1

switch(config-if)# no switchport

switch(config-if)# vrrp 7

switch(config-if-vrrp)#

This example shows how to create a VRRP group and configure an IPv4 address for the group:

switch# configure terminal

switch(config)# interface ethernet 2/1

switch(config-if)# no switchport

switch(config-if)# vrrp 7

switch(config-if-vrrp)# address 10.0.0.10

switch(config-if-vrrp)# no shutdown

switch(config-if-vrrp)#

Related Commands

Command	Description
clear vrrp	Clears all the software counters for the specified virtual router.
feature vrrp	Enables VRRP.
address (VRRP)	Adds a primary or secondary IP address to a virtual router.
show vrrp	Displays VRRP configuration information.

vrrpv3 address-family

To create a Virtual Router Redundancy Protocol version 3(VRRPv3) group and enter VRRPv3 group configuration mode, use the vrrpv3 address-family command. To remove a VRRPv3 group, use the no form of this command.

vrrpv3 number address-family [ ipv4 | ipv6 ]

no vrrpv3

Syntax Description

number	VRRPv3 group number. The range is from 1 to 255.
ipv4	Specifies IPv4 address.
ipv6	Specifies IPv6 address.

Command Modes

Interface configuration (config-if)

Command History

Release	Modified
7.3(0)N1(1)	This command was introduced.

Usage Guidelines

Ensure that you configure at least one IP address before you attempt to enable a virtual router group.

Examples

The following example shows how to create a VRRPv3 group and configure an IP address for the group:

switch# configure terminal

switch(config)# interface ethernet 2/1

switch(config-if)# vrrpv3 5 address-family ipv4

switch(config-if-vrrpv3-group)# address 100.0.1.10 primary

Related Commands

Command	Description
feature vrrp	Enables VRRP.

vrrs leader

To specify the name of the leader to be registered with Virtual Router Redundancy Service(VRRS), use the vrrs leader command.

vrrs leader vrrs-leader-name

Syntax Description

vrrs-leader-name

VRRS leader name.

Command Modes

VRRPv3 group configuration (config-if-vrrpv3-group)

Command History

Release	Modified
7.3(0)N1(1)	This command was introduced.

Examples

The following example shows how to specify a leader’s name to be registered with VRRS:

switch# configure terminal

switch(config)# interface ethernet 2/1

switch(config-if)# vrrpv3 5 address-family ipv4

switch(config-if-vrrpv3-group)# address 100.0.1.10 primary

switch(config-if-vrrpv3-group)# description group3

switch(config-if-vrrpv3-group)# vrrs leader leader1

switch(config-if-vrrpv3-group)# shutdown

Related Commands

Command	Description
vrrpv3 address-family	Creates a VRRPv3 group and enter VRRPv3 group configuration mode.

vrrs pathway

To define the Virtual Router Redundancy Service (VRRS) pathway for a VRRS group and enter VRRS pathway configuration mode, use the vrrs pathway command.

vrrs pathway vrrs-tag

Syntax Description

vrrs-tag

VRRS tag.

Command Modes

Interface configuration (config-if)

Command History

Release	Modified
7.3(0)N1(1)	This command was introduced.

Examples

The following example shows how to configure VRRS pathway:

switch# configure terminal

switch(config)# interface port-channel 100

switch(config-if)# ip address 209.165.200.230 255.255255.224

switch(config-if)# vrrpvs pathway path1

switch(config-if-vrrs-pw)#

Related Commands

Command	Description
show vrrs pathway	Displays the VRRS pathway information for different pathway states.
