Message 2 Loopback test packet fail message WAGT-(tsa):Rcvd TSM_SWAGT_X3_ALLCHN_LOOPBACK_REQ msg • If both packets fail, a failed test result is sent to the internal FTOS task manager (TSM). • Another test is initiated 45 seconds later. • If the FTOS task manager (TSM) receives 3 consecutive failed messages (indicating 6 loopback tests have failed), a syslog message appears indicating the port pipe with the failure. Message 3 Consecutive failure syslog message RPM0-P:CP %TSM-2-LP_LOOPBACK_FAIL: Linecard-SFM dataplane loopback test failed on linecard 1, PP0: Fail, PP1: Fail %RPM0-P:CP %TSM-2-SFM_ERR: Error detected in SFM 0 during loopback tests% • If the loopback packet does not come back, the system reads the CRC error values on S3, to determine whether or not the SFM is bad. If the SFM is bad, the system reports CRC error as reason for SFM problem state in the output of the show sfm command.
