Monitoring the Configuration of VRIDs

Purpose

Display information about all configured VRIDs.

Action

To display a detailed summary of all configured VRIDs:  

host1#show ip vrrp
Interface: FastEthernet3/0 vrrpVrid: 1
  primary address: 12.60.1.1
  operational state: init
  admin state: disabled
  up time: N/A
  interval: 1 second
  Learning timer mode: disabled
  last error status: no error
  priority: 100  ( admin priority: 100 )
  auth type: none
  preemption: enabled
  accept data: disabled
  assoc address(es): none
  track object:  xyz  state:  Up  decrement:  10

To display the summary count on all configured VRIDs:

host1#show ip vrrp summary
ip interfaces with vrrp: 1
  entries: 10
  entries enabled: 10
  entries with owner priority: 1
  entries in init state: 0
  entries in backup state: 9
  entries in master state: 1
  entries performing tracking: 2

To display a brief summary of all configured VRIDs:

host1#show ip vrrp brief
Interface                VRID  Primary Address  State   Adv  Pri  Admin
-----------------------  ----  ---------------  ------  ---  ---  --------

Table 25 lists the show ip vrrp command and show ip vrrp summary command output fields.

Table 25: show ip vrrp and show ip vrrp summary Output Fields

Field Name

Field Description

Interface

Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interface specifier and VRID

primary address

IP address used while in master state; not necessarily an associated address

operational state

State of the VRRP router:

  • master—Router that forwards packets sent to the IP address associated with the virtual router.
  • backup—Router that forwards packets if the current master router fails. Provides the current master router’s IP address.
  • init—Router that transitions to either the master state or backup state depending on the priority assigned.

admin state

Administrative status: enabled or disabled.

up time

Number of seconds that the VRID has been enabled in non-init state

interval

VRRP advertisement interval in seconds or milliseconds

Learning timer mode

Mode of the VRRP router:

  • enabled—Router learns the VRRP advertisement interval that is useful in case of failure of the master router
  • disabled—Router does not learn the VRRP advertisement interval.

last error status

Help text used to debug any error detected

priority

Priority value of VRRP router

admin priority

Priority of the VRRP administrative router

auth type

Type of authentication used by VRRP: none or text

preemption

Status of VRRP router preemption: enabled or disabled

  • enabled—Backup router always takes over the responsibility of the master router.
  • disabled—Backup router with lower-priority remains in backup state.

accept data

Accept data status of the VRRP router:

  • enabled—Enables the backup router to process packets with an IP destination address equivalent to the virtual addresses while the backup router is in the master state.
  • disabled—Disables the processing of data packets by the backup router while the router is in the master state.

assoc address(es)

IP addresses associated with the VRID

track object

Name and state of the tracked object and the value by which the object priority changes following an object state change

ip interfaces with vrrp

Number of IP interfaces using VRRP

entries

Total number of entries

entries enabled

Number of enabled entries

entries with owner priority

Number of entries with an owner priority

entries in init state

Number of entries in an initialization state

entries in backup state

Number of entries in a backup state

entries in master state

Number of entries in a master state

entries performing tracking

Number of entries performing tracking functions

VRID

VRRP router instance configured on this interface

Primary Address

IP address used while in master state; not necessarily an associated address

State

Operational state of the VRRP router:

  • master—Router that forwards packets sent to the IP address associated with the virtual router.
  • backup—Router that forwards packets if the current master router fails. Provides the current master router’s IP address.
  • init—Router that transitions to either the master or backup router depending on the priority assigned.

Adv

Advertisement interval, in seconds

Pri

Priority assigned to this router

Admin

Administrative state of the VRID: enabled or disabled
