Monitoring VRRP

You can use several VRRP show commands to display the details of your VRRP configuration.

baseline ip vrrp
Use to establish the baseline on all VRRP statistics as the current value.

Example
host1#baseline ip vrrp
show ip vrrp

Use to display a detailed summary of all configured VRIDs.

Use the interface keyword to specify a specific Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interface.

Use the summary keyword to display a summary count on all configured VRIDs

show ip vrrp brief

Use to display a brief summary of all configured VRIDs.

Use the interface keyword to specify a specific Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interface.

Field descriptions

Interface—Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interface specifier

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 VRRP router: master, backup, or init

Example
host1#show ip vrrp brief

-----------------------  ----  ---------------  ------  ---  ---  --------
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 
show ip vrrp neighbor

Use to display neighbors currently known to the VRRP routers.

A neighbor—a router that shares a given VRID with the VRRP router—is known to the VRRP router only when the neighbor becomes a master for an IP address and sends VRRP advertisements to that effect. If a router sharing the VRID has not yet become a master, then the local router remains unaware of this neighbor and this command does not display that neighbor.

Use the interface keyword to specify a specific Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interface.

Field descriptions

Interface—Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interface specifier and VRID of neighbors known to the VRRP router

time discovered—Date and time that the neighbor was detected

primary address—Primary IP address of neighbor

adv interval (sec)—VRRP advertisement interval in seconds

priority—Priority status of VRRP router (255 = owner)

auth type—VRRP authentication type: none or text

assoc address(es)—IP addresses associated with the VRID that are advertised by the neighbor
Example
host1#show ip vrrp neighbor
Interface: fastEthernet5/0.0 vrrpVrid: 1
  time discovered: 08/09/2001 07:44
  primary address: 10.0.0.1

  priority: 255 (owner)
  auth type: none
  assoc address(es): 11.0.0.1, 110.0.0.1, 111.0.0.1
show ip vrrp statistics

Use to display statistics of configured VRRP routers and each individual VRID.

Use the delta keyword with the show ip vrrp statistics command to view the baseline statistics.
