Monitoring the Statistics of VRRP Routers

Purpose

Display global statistics, interface statistics, or statistics per interface and VRID of configured VRRP routers.

Action

To display the statistics per interface:  

host1#show ip vrrp statistics interface fastEthernet 4/0
Globals:
  checksumErrors: 0
  versionErrors: 0
  vrIdErrors: 1
  iccErrors: 0
  txErrors: 0
  rxErrors: 0
Interface: fastEthernet4/0 vrrpVrid: 1
  becomeMaster: 10
  advertiseRcvd: 0
  advertiseIntervalErrors: 0
  authFailures: 0
  ipTtlErrors: 0
  priorityZeroPktsRcvd: 0
  priorityZeroPktsSent: 9
  invalidTypePktsRcvd: 0
  addressListErrors: 0
  invalidAuthType: 0
  authTypeMismatch: 0
  packetLengthErrors: 0
Interface: fastEthernet4/0 vrrpVrid: 50
  becomeMaster: 0
  advertiseRcvd: 1000
  advertiseIntervalErrors: 0
  authFailures: 0
  ipTtlErrors: 0
  priorityZeroPktsRcvd: 0
  priorityZeroPktsSent: 0
  invalidTypePktsRcvd: 0
  addressListErrors: 0
  invalidAuthType: 0
  authTypeMismatch: 0
  packetLengthErrors: 0 

To display the statistics per interface and VRID:

host1#show ip vrrp statistics interface fastEthernet 4/0 1
Interface: fastEthernet4/0 vrrpVrid: 1
  becomeMaster: 0
  advertiseRcvd: 0
  advertiseIntervalErrors: 0
  authFailures: 0
  ipTtlErrors: 0
  priorityZeroPktsRcvd: 0
  priorityZeroPktsSent: 0
  invalidTypePktsRcvd: 0
  addressListErrors: 0
  invalidAuthType: 0
  authTypeMismatch: 0
  packetLengthErrors: 0 

To display the global statistics of a VRRP router:

host1#show ip vrrp statistics global
Globals:
  checksumErrors: 0
  versionErrors: 0
  vrIdErrors: 0
  iccErrors: 0
  txErrors: 0
  rxErrors: 0

Meaning

Table 27 lists the show ip vrrp statistics command output fields.
