State |
|
Pol Id | The value that uniquely identifies a priority control policy |
Base Priority | 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 |
InUse Priority | The current in-use priority associated with the VRRP virtual router instance |
Msg Int | The administrative advertisement message timer used by the master virtual router instance to send VRRP advertisement messages and to derive the master down timer as backup |
Inh Int | Yes — 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 |
No — 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; if the VRRP instance is operating as a master, this value has no effect | |
Backup Addr | The backup virtual router IP address |
BFD | Indicates BFD is enabled |
VRRP State | Specifies whether the VRRP instance is operating in a master or backup state |
Policy ID | The VRRP priority control policy associated with the VRRP virtual router instance A value of 0 indicates that no control policy is associated with the virtual router instance |
Preempt Mode | Yes — the preempt mode is enabled on the virtual router instance where it will preempt a VRRP master with a lower priority |
No — the preempt mode is disabled and prevents the non-owner virtual router instance from preempting another, less desirable virtual router | |
Ping Reply | Yes — a non-owner master is enabled to reply to ICMP Echo requests directed to the virtual router instance IP addresses Ping Reply is valid only if the VRRP virtual router instance associated with this entry is a non-owner A non-owner backup virtual router never responds to such ICMP echo requests irrespective if Ping Reply is enabled |
No — ICMP echo requests to the virtual router instance IP addresses are discarded | |
Telnet Reply | Yes — non-owner masters can to reply to TCP port 23 Telnet requests directed at the virtual router instances IP addresses |
No — telnet requests to the virtual router instance IP addresses are discarded | |

Primary IP | The IP address of the VRRP owner |
Up Time | The date and time when the operational state of the event last changed |
Virt MAC Addr | The virtual MAC address used in ARP responses when the VRRP virtual router instance is operating as a master |

Addr List Mismatch | Specifies whether a trap was generated when the IP address list received in the advertisement messages received from the current master did not match the configured IP address list This is an edge triggered notification; a second trap will not be generated for a packet from the same master until this event has been cleared |
Master Priority | The priority of the virtual router instance which is the current master |

VRRP Policy Output — The following output is an example of VRRP policy information, and Table 50 describes the fields.
Label | Description |
Policy Id | The VRRP priority control policy associated with the VRRP virtual router instance A value of 0 indicates that no control policy is associated with the virtual router instance |
Current Priority & Effects | |
Current Explicit | When multiple explicitly defined events associated with the priority control policy happen simultaneously, the lowest value of all the current explicit priorities will be used as the in-use priority for the virtual router |
Current Delta Sum | The sum of the priorities of all the delta events when multiple delta events associated with the priority control policy happen simultaneously; this sum is subtracted from the base priority of the virtual router to give the in-use priority |
Delta Limit | The delta-in-use-limit for a VRRP policy; once the total sum of all delta events has been calculated and subtracted from the base-priority of the virtual router, the result is compared to the delta-in-use-limit value; if the result is less than this value, the delta-in-use-limit value is used as the virtual router in-use priority value; if an explicit priority control event overrides the delta priority control events, the delta-in-use-limit has no effect If the delta-in-use-limit is 0, the sum of the delta priority control events to reduce the virtual router's in-use-priority to 0 can prevent it from becoming or staying master |
Current Priority | The configured delta-in-use-limit priority for a VRRP priority control policy or the configured delta or explicit priority for a priority control event |
Applied | The number of virtual router instances to which the policy has been applied; the policy cannot be deleted unless this value is 0 |
Description | A text string which describes the VRRP policy |
Event Type & ID | A delta priority event is a conditional event defined in a priority control policy that subtracts a given amount from the base priority to give the current in-use priority for the VRRP virtual router instances to which the policy is applied An explicit priority event is a conditional event defined in a priority control policy that explicitly defines the in-use priority for the VRRP virtual router instances to which the policy is applied Explicit events override all delta events; when multiple explicit events occur simultaneously, the event with the lowest priority value defines the in-use priority |
Event Oper State | The operational state of the event |
Hold Set Remaining | The amount of time that must pass before the set state for a VRRP priority control event can transition to the cleared state to dampen flapping events |
Priority & Effect | Delta — 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 |
Explicit — 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 | |
In Use | Specifies whether the event is currently affecting the in-use priority of some virtual router |
