Viewing statistics for all VRRP instances on the router
Syntax:
show vrrp [statistics]
show vrrp ipv6 statistics
Displays the following VRRP statistics:
Global VRRP statistics for the router
VRRP statistics for all VRs configured on the router:
- State
Indicates whether the router is a backup or the current master of the VR.
- Uptime
The amount of time the router has been up since the last reboot.
- Virtual MAC Address
The virtual MAC address for the VR instance.
- master's IP Address
The IP address used as the source IP address in the last advertisement packet received from the VR master. If this VR is the master, this is the primary IP address of the VR. If the VR is disabled, this value appears as 0.0.0.0 for IPv4, and 0:0:0:0:0:ffff:0:0 for IPv6.
- Associated IP Address Count
Number of VIPs.
- Advertise Packets Rx
The number of VRRP master advertisements the VR has received from other VRRP routers since the last reboot.
- Zero Priority Tx
The number of VRRP advertisement packets received with the priority field set to 0 (zero.)
- Bad Length Pkts
The number of VRRp packets received with missing fields of information.
- Mismatched Interval Pkts
The number of VRRP packets received from other routers (since the last reboot) with an advertisement interval that is different from the interval configured on the current VR.
VRRP packets received with an interval mismatch are dropped.
- Mismatched IP TTL Pkts
The number of VRRP packets received with the IP TTL field not set to 255. Such packets are dropped.
- Near Failovers
Tracks the occurrence of "near failovers" on the backup VRRP routers. This makes visible any difficulties the VRRP routers are having receiving the "heartbeat" advertisement from the master router. A "near failover" is one that is within one missed VRRP advertisement packet of beginning the master determination process.
- Become master
The number of times the VR has become the master since the last reboot.
- Zero Priority Tx
The number of VRRP advertisement packets sent with the priority field set to 0 (zero.)
- Bad Type Pkts
The number of VRRP packets received with packet type not equal to 1 (that is, not an advertisement packet.)
- Mismatched Addr List Pkts
The number of VRRP packets received wherein the list of VIPs does not match the locally configured VIPs for a VR.
- Mismatched Auth Type Pkts
The number of VRRP packets received with the authentication type not equal to 0 (zero, which is no authentication.)
