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

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
