[no] port-down port-id
config>vrrp>policy>priority-event
Supported on all 7210 SAS platforms as described in this document
This command configures a port down priority control event that monitors the operational state of a port or SONET/SDH channel. When the port or channel enters the operational down state, the event is considered set. When the port or channel enters the operational up state, the event is considered cleared.
Multiple unique port-down event nodes can be configured within the priority-event context up to the overall limit of 32 events, defined in any combination of types.
The port-down command can reference an arbitrary port or channel. The port or channel does not need to be preprovisioned or populated within the system. The operational state of the port-down event will indicate:
Set – non-provisioned
Set – not populated
Set – down
Cleared – up
When the port or channel is provisioned, populated, or enters the operationally up or down state, the event operational state is updated appropriately.
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 instances in-use priority value. As the event transitions from cleared to set, a hold-set timer is loaded with the value configured by the events hold-set command. 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. When the events hold-set expires, the effects of the events 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 this command deletes the specific port or channel monitoring event. The event may be removed at anytime. When the event is removed, the in-use priority of all associated virtual router instances will be re-evaluated. The events hold-set timer has no effect on the removal procedure.
no port-down
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. A port and a specific channel on the port are considered to be separate entities. A port and a channel on the port can be monitored by separate events in the same policy.
