VRRP Command Reference
250 7705 SAR OS Router Configuration Guide
When the event enters the operationally down, non-provisioned, or non-populated state, the event is
considered to be set. When an event transitions from clear to set, the set is processed immediately and
must be reflected in the associated virtual router instance in-use priority value. As the event transitions
from cleared to set, the hold-set timer is started. This timer prevents the event from clearing until it
expires, damping the effect of event flapping. If the event clears and becomes set again before the
hold-set timer expires, the timer is reset to the hold-set value, extending the time before another clear
can take effect.
When the event enters the operationally up state, the event is considered to be cleared. Once the event
hold set expires, the effects of the event priority value are immediately removed from the in-use
priority of all associated virtual router instances.
The actual effect on the virtual router instance in-use priority value depends on the defined event
priority and its delta or explicit nature.
The no form of the command deletes the specific port monitoring event. The event can be removed at
any time. If the event is removed, the in-use priority of all associated virtual router instances is
re-evaluated. The event’s hold-set timer has no effect on the removal procedure.
Default no port-down
Parameters port-id — specifies the port ID of the port monitored by the VRRP priority control event
The port ID can only be monitored by a single event in this policy. The port can be monitored
by multiple VRRP priority control policies.
If the port is provisioned, but the port has not been populated, the appropriate event
operational state is set – non-populated.
If the port is not provisioned, the event operational state is set – non-provisioned.
Values port-id slot/mda/port
bundle-type-slot/mda.<bundle-num>
bundle keyword
type ppp
bundle-num 1 to 32
route-unknown
Syntax route-unknown ip-prefix/mask
