Description This command specifies the amount of time that must pass before the set state for a VRRP priority
control event event can transition to the cleared state to dampen flapping events. A flapping event
continually transitions between clear and set.
The hold-set command is used to dampen the effect of a flapping event. The hold-set value is loaded
into a hold set timer that prevents a set event from transitioning to the cleared state until it expires.
Each time an event transitions between cleared and set, the timer is loaded and begins a countdown to
zero. When the timer reaches zero, the event is allowed to enter the cleared state. Entering the cleared
state is dependent on the object controlling the event, conforming to the requirements defined in the
event itself. It is possible, on some event types, to have another set action reload the hold-set timer.
This extends the amount of time that must expire before entering the cleared state.
Once the hold set timer expires and the event meets the cleared state requirements or is set to a lower
threshold, the current set effect on the virtual router instances in-use priority can be removed. As with
lag-port-down events, this may be a decrease in the set effect if the clearing amounts to a lower set
threshold.
The hold-set command can be executed at anytime. If the hold-set timer value is configured larger than
the new seconds setting, the timer is loaded with the new hold-set value.
The no form of the command reverts the default value.
Default 0 — The hold-set timer is disabled so event transitions are processed immediately.
Parameters seconds — The 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.
The value of 0 disables the hold set timer, preventing any delay in processing lower set
thresholds or cleared events.
Values 0 to 86400
