Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Chapter: Show Commands

Show Commands

This chapter describes the Cisco NX-OS Hot Standby Router Protocol (HSRP) show commands.

show hsrp

To display Hot Standby Router Protocol (HSRP) information for each HSRP group, use the show hsrp command.

show hsrp [ interface { ethernet slot / port | port-channel number | vlan vlan-id }] [ group group-number ] [ active | init | listen | standby ] [ all ] [ brief ] [ detail ] [ ipv4 ]

 
Syntax Description

interface

(Optional) Specifies the interface for which to display HSRP information.

ethernet slot / port

Specifies the Ethernet interface and the slot number and port number. The slot number is from 1 to 255, and the port number is from 1 to 128.

port-channel number

Specifies the EtherChannel interface and EtherChannel number. The range is from 1 to 4096.

vlan vlan-id

Specifies the VLAN interface. The range is from 1 to 4094.

group group-number

(Optional) Specifies the HSRP group number of the interface to display information about. The range is from 0 to 4095.

active

(Optional) Displays HSRP groups that are in an active state.

init

(Optional) Displays HSRP groups that are in an initialization state.

listen

(Optional) Displays HSRP groups that are in an listen state.

standby

(Optional) Displays HSRP groups that are in an standby state.

all

(Optional) Displays all HSRP groups.

brief

(Optional) Summarizes each virtual gateway or virtual forwarder with a single line of output.

detail

(Optional) Displays detailed information about HSRP groups.

ipv4

(Optional) Displays HSRP IPv4 groups.

6.0(2)N1(1)

This command was introduced.

 
Usage Guidelines

Use the show hsrp command to display information about HSRP groups. The brief keyword displays a single line of information about each virtual gateway or virtual forwarder.

If you have not configured authentication, the show hsrp command will display the following string:

Authentication text "cisco"
 

This is the default behavior of HSRP as defined in RFC 2281 :

If no authentication data is configured, the RECOMMENDED default
value is 0x63 0x69 0x73 0x63 0x6F 0x00 0x00 0x00.
 

This command does not require a license.

Note Make sure the LAN Base Services license is installed on the switch to enable Layer 3 interfaces.

Examples

This example shows how to display the default information about HSRP:

switch# show hsrp
Vlan1 - Group 1 (HSRP-V1) (IPv4)
Local state is Active, priority 150 (Cfged 150), may preempt
Forwarding threshold(for vPC), lower: 1 upper: 150
Preemption Delay (Seconds) Reload:300
Hellotime 3 sec, holdtime 10 sec
Next hello sent in 0.793000 sec(s)
Virtual IP address is 10.1.1.3 (Cfged)
Active router is local
Standby router is unknown
Authentication text "cisco"
Virtual mac address is 0000.0c07.ac01 (Default MAC)
17 state changes, last state change 1w0d
IP redundancy name is hsrp-Vlan1-1 (default)
...
 

Note The authentication text string in the preceding example indicates that authentication has not been configured on the interface.

This example shows how to display a brief summary of HSRP information:

switch# show hsrp brief
P indicates configured to preempt.
|
Interface Grp Prio P State Active addr Standby addr Group addr
Vlan1 1 150 P Active local unknown 10.1.1.3 (conf)
Vlan2 2 150 P Active local unknown 10.1.2.3 (conf)
...
