Viewing IPv6 VRRP Statistics

View IPv6 VRRP statistics to monitor network performance

Procedure

  1. To enter User EXEC mode, log on to the switch.
  2. View statistics for the device and for all interfaces:

    show ipv6 vrrp statistics [link-local WORD<0–127>]] [vrid <1–255>]

Example

View IPv6 VRRP statistics for VRID 1.

Switch:1(config)#show ipv6 vrrp statistics vrid 1

Job Aid

The following table describes the output for the show ipv6 vrrp statistics command.

Table 1. show ipv6 vrrp statistics command output

Heading

Description

CHK_SUM_ERR

Shows the number of VRRP packets received with an invalid VRRP checksum value.

VERSION_ERR

Shows the number of VRRP packets received with an unknown or unsupported version number.

VRID_ERR

Shows the number of VRRP packets received with an invalid VrID for this virtual router.

BECOME_MASTER

Shows the total number of times that the state of this virtual router has transitioned to master. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of DiscontinuityTime.

ADVERTISE_RCV

Shows the total number of VRRP advertisements received by this virtual router. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of DiscontinuityTime.

ADVERTISE_INT_ERR

Shows the total number of VRRP advertisement packets received for which the advertisement interval is different than the one configured for the local virtual router. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of DiscontinuityTime.

TTL_ERR

Shows the total number of VRRP packets received by the virtual router with IPv4 TTL (for VRRP over IPv4) or IPv6 Hop Limit (for VRRP over IPv6) not equal to 255. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of DiscontinuityTime.

PRIO_0_RCV

Shows the total number of VRRP packets received by the virtual router with a priority of 0. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of DiscontinuityTime.

PRIO_0_SENT

Shows the total number of VRRP packets sent by the virtual router with a priority of 0. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of DiscontinuityTime.

INVALID_TYPE_ERR

Shows the number of VRRP packets received by the virtual router with an invalid value in the 'type' field. Discontinuities in the value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of DiscontinuityTime.

ADDRESS_LIST_ERR

Shows the total number of packets received for which the address list does not match the locally configured list for the virtual router. Discontinuities in the value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of DiscontinuityTime.

UNKNOWN_AUTHTYPE

Shows the total number of packets received with an unknown authentication type.

PACKLEN_ERR

Shows the total number of packets received with a packet length less than the length of the VRRP header. Discontinuities in the value of this counter can occur at reinitialization of the management system, and at other times as indicated by the value of DiscontinuityTime.
