Use thiscommand, with the line option, to delay that trigger event by 100ms.By default, path alarms (AIS, RDI, LOP) do not cause (or trigger) the interface line protocol to go down.The delay triggers command, used with the path option, can be used to trigger this action.SONET Port Recovery MechanismThis feature automatically clears a condition that could cause a SONET port to hang, and stop sending andreceiving data. When enabled, FTOS continuously polls status registers on SONET line cards. A port hangis declared when backpressure is detected on the port, and the port is brought down and then back up toclear the condition.The default detection interval is 60 seconds.To keep a port in shutdown use the use the hardware monitor mac action-on-error port-shutdown command.Task Command Syntax Command ModeDelay triggering the line or path alarmswith a 100ms delay.delay triggers {line [lrdi | sd-ber | sf-ber]| path [pais | prdi] }INTERFACENote: FTOS does not support configurable thresholds; delay triggers uses a default value of 100 ms.Task Command Syntax Command ModeImplement a detection interval to find andrecover hung SONET portssonet-port-recover detection-intervalinterval (16-500 seconds; default is 60seconds)INTERFACE
