7210SAS>show>router#
Table: Output fields: VRRP instance
Label Description

Interface name

The name of the IP interface

VR ID

The virtual router ID for the IP interface

Own

Owner

Yes — Specifies that the virtual router instance as owning the virtual router IP addresses

No — Indicates that the virtual router instance is operating as a non-owner

Adm

Up — Indicates that the administrative state of the VRRP instance is up

Down — Indicates that the administrative state of the VRRP instance is down

Opr

Up — Indicates that the operational state of the VRRP instance is up

Down — Indicates that the operational state of the VRRP instance is down

State

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).

Pol ID

The value that uniquely identifies a Priority Control Policy

Base Priority

The base-priority value is 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

SSH Reply

Yes — Non-owner masters can to reply to SSH requests directed at the virtual router instances IP addresses

No — All SSH request messages destined for the non-owner virtual router instance IP addresses are discarded

Primary IP of Master

The IP address of the VRRP master

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

Auth Type

Specifies the VRRP authentication Type 0 (no authentication), Type 1 (simple password), or Type 2 (MD5) for the virtual router

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

Master Since

The date and time when operational state of the virtual router changed to master

For a backup virtual router, this value specifies the date and time when it received the first VRRP advertisement message from the virtual router which is the current master.

A:ALA-A# 
Table: Output fields: VRRP policy
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. When 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 specific 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 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

Table: Output fields: VRRP policy event
Label Description

Description

A text string which describes the VRRP policy

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

The base router priority for the virtual router instance used in the master election process

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.

Applied

The number of virtual router instances to which the policy has been applied. The policy cannot be deleted unless this value is 0.

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. When 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.

Applied to Interface Name

The interface name where the VRRP policy is applied

VR ID

The virtual router ID for the IP interface

Opr

Up — Indicates that the operational state of the VRRP instance is up

Down — Indicates that the operational state of the VRRP instance is down

Base Pri

The base priority used by the virtual router instance

InUse Priority

The current in-use priority associated with the VRRP virtual router instance

Master Priority

The priority of the virtual router instance which is the current master

Priority

The base priority used by the virtual router instance

Priority Effect

Delta — A delta priority event is a conditional event defined in a priority control policy that subtracts a specific amount from the base priority to give the current in-use priority for the VRRP virtual router instances to which the policy is applied.

Explicit — 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.

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

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

The base priority used by the virtual router instance

Priority Effect

Delta — The priority-level value is subtracted from the associated virtual router instance 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.

Hold Set Config

The configured number of seconds that the hold-set timer waits after an event enters a set state or enters a higher threshold set state, depending on the event type.

Value In Use

Yes — The event is currently affecting the in-use priority of some virtual router

No — The event is not affecting the in-use priority of some virtual router

# trans to Set

The number of times the event has transitioned to one of the 'set' states

Last Transition

The time and date when the operational state of the event last changed
