Current Delta Sum
The sum of the priorities of all the delta events when multiple delta
events associated with the priority control policy happen simultane-
ously. 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 con-
trol 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 pri-
ority control event can transition to the cleared state to dampen flap-
ping 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 val-
ues 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.
