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.
