# 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 19 lists the show ip vrrp command and show ip vrrp summary command output fields.

Table 19: 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
