Command Syntax delay triggers {line [lrdi | sd-ber | sf-ber] | path [pais | prdi] } Command Mode INTERFACE By default, certain alarms (LOS, LOF, LAIS, PLOP) bring the line protocol down immediately. Use this command, 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. Note: FTOS does not support configurable thresholds; delay triggers uses a default value of 100 ms. SONET Port Recovery Mechanism This feature automatically clears a condition that could cause a SONET port to hang, and stop sending and receiving data. When enabled, FTOS continuously polls status registers on SONET line cards. A port hang is declared when backpressure is detected on the port, and the port is brought down and then back up to clear the condition.The default detection interval is 60 seconds. Task Command Syntax Implement a detection interval to find and recover hung SONET ports sonet-port-recover detection-interval interval (16-500 seconds; default is 60 seconds) Command Mode INTERFACE To keep a port in shutdown use the use the hardware monitor mac action-on-error port-shutdown command. 1014 | SONET/SDH
