Description
This command displays information for VRRP instances.
If no command line options are specified, summary information for all VRRP instances displays.
Parameters
interface ip-int-name
Displays detailed information for the VRRP instances on the specified IP interface including status and statistics.
Default
vrid virtual-router-id
Displays detailed information for the specified VRRP instance on the IP interface.
Default
Values
ipv6
Specifies the IPv6 instance.
Output
VRRP Instance Output
The following table describes the instance command output fields for VRRP.
 
When owner, backup defines the IP addresses that are advertised within VRRP advertisement messages.
When non-owner, backup actually creates an IP interface IP address used for routing IP packets and communicating with the system when the access commands are defined (ping-reply, telnet-reply, and ssh-reply).
The base-priority value used to derive the in-use priority of the virtual router instance as modified by any optional VRRP priority control policy.
When the VRRP instance is a non-owner and is operating as a backup and the master-int-inherit command is enabled, the master down timer is indirectly derived from the value in the advertisement interval field of the VRRP message received from the current master.
When the VRRP instance is operating as a backup and the master-int-inherit command is not enabled, the configured advertisement interval is matched against the value in the advertisement interval field of the VRRP message received from the current master. If the two values do not match then the VRRP advertisement is discarded.

Syntax
policy [vrrp-policy-id [event event-type specific-qualifier]]
Context

Description
This command displays VRRP priority control policy information.
If no command line options are specified, a summary of the VRRP priority control event policies displays.
Parameters
vrrp-policy-id
Displays information on the specified priority control policy ID.
Default
Values
event event-type
Displays information on the specified VRRP priority control event within the policy ID.
Default
Values
port-down port-id
lag-port-down lag-id
host-unreachable host-ip-addr
route-unknown route-prefix/mask
mc-ipsec-non-forwarding
specific-qualifier
Display information about the specified qualifier.
Values
 
Output
VRRP Policy Output
The following table describes the VRRP policy command output fields.
 
The priority-level value is subtracted from the associated virtual router instance’s base priority when the event is set and no explicit events are set. The sum of the priority event priority-level values on all set delta priority events are subtracted from the virtual router base priority to derive the virtual router instance in-use priority value.
If the delta priority event is cleared, the priority-level is no longer used in the in-use priority calculation.
The priority-level value is used to override the base priority of the virtual router instance if the priority event is set and no other explicit priority event is set with a lower priority-level.
The set explicit priority value with the lowest priority-level determines the actual in-use protocol value for all virtual router instances associated with the policy.

The following table describes a specific event VRRP policy command output fields.
 
The priority-level value is subtracted from the associated virtual router instance’s base priority when the event is set and no explicit events are set. The sum of the priority event priority-level values on all set delta priority events are subtracted from the virtual router base priority to derive the virtual router instance in-use priority value.
If the delta priority event is cleared, the priority-level is no longer used in the in-use priority calculation.
The priority-level value is used to override the base priority of the virtual router instance if the priority event is set and no other explicit priority event is set with a lower priority-level.
The set explicit priority value with the lowest priority-level determines the actual in-use protocol value for all virtual router instances associated with the policy.

rate
When the rate keyword is specified, the rate-per-second for each statistic is displayed instead of the delta.
ipv6
Specifies to monitor IPv6 instances.
