    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
    -----------------------  ----  ---------------  ------  ---  ---  --------
    fastEthernet12/8.1.1      255  123.123.123.123    init    1  100  disabled
    gigabitEthernet12/8.1.1     1          1.1.1.1  master    1  254  enabled 

    Meaning

    Table 1 lists the show ip vrrp command and show ip vrrp summary command output fields.

    Table 1: 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
