Description

Port

Displays the port number.

Level

Select Section or Path.

Received Trace Mode

Enable the trace expected string by choosing Off/None, Auto, or Manual from the Trace Mode drop-down list:

  • Off/None: Trace mode is disabled.

  • Auto: Uses the first string received from port at the other end as the baseline string. An alarm is raised when a string that differs from the baseline is received. For STM-N ports, Auto is recommended, since Manual mode requires you to trace the circuit on the Edit Circuit window to determine whether the port is the source or destination path.

  • Manual: Uses the Current Expected String field as the baseline string. An alarm is raised when a string that differs from the Current Expected String is received.
