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.

Table 27: show ip vrrp statistics Output Fields

Field Name	Field Description
Globals
checksumErrors	Total number of VRRP packets received with an invalid VRRP checksum value
versionErrors	Total number of VRRP packets received with an unknown or unsupported version number
vrIdErrors	Total number of VRRP packets received with an invalid VRID for this virtual router
iccErrors	Count of line module notifications that did not make it to the controller
txErrors	Count of advertisements that did not get sent due to resource limitations
rxErrors	Count of advertisements received that could not be parsed by VRRP applications
Interface	Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interface specifier and VRID
becomeMaster	Total number of times that this VRID state has transitioned to master
advertiseRcvd	Total number of VRRP advertisements received
advertiseIntervalErrors	Total number of VRRP advertisement packets received for which the advertisement interval is different from the one configured for the VRID
authFailures	Total number of VRRP packets received that do not pass the authentication check
ipTtlErrors	Total number of VRRP packets received with IP TTL (time-to-live) not equal to 255
priorityZeroPktsRcvd	Total number of VRRP packets received with a priority of 0
priorityZeroPktsSent	Total number of VRRP packets sent with a priority of 0
invalidTypePktsRcvd	Total number of VRRP packets received with an invalid value in the Type field
addressListErrors	Total number of VRRP packets received for which the address list does not match the locally configured list for the VRID
invalidAuthType	Total number of VRRP packets received with an unknown authentication type
authTypeMismatch	Total number of VRRP packets received with an authentication type not equal to the locally configured authentication method
packetLengthErrors	Total number of VRRP packets received with a packet length less than the length of the VRRP header
