Label Description
Description
A text string which describes the VRRP policy.
Policy Id
The VRRP priority control policy associated with the VRRP vir-
tual 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 pri-
ority control policy happen simultaneously, the lowest value of
all the current explicit priorities will be used as the in-use prior-
ity 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. 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 prior-
ity 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 pre-
vent it from becoming or staying master.
