Usage Guidelines

This command displays the events for the specified WAN PHY ports. The display shows whether each parameter is in the alarm or normal state; the alarm state includes alarm, warning, and error states.

This command displays notices for the following events:
  • LOS: loss of signal.

  • SEF: Severely Error Frame.

  • LOF: loss of frame.

  • LOP: loss of pointer.

  • AIS-L: alarm indication signal, line.

  • AIS-P: alarm indication signal, path.

  • RDI-L: remote defection indication, line.

  • FarEnd PLM-P/LCD-P: Far end path label mismatch / loss of code-group delineation.

  • FarEnd AIS-P/LCD-P: Far end path alarm indication signal / path loss of pointer.

  • PLM-P: Path label mismatch.

  • LCD-P: path loss of code-group delineation.

If you do not specify a port number, range of ports, or tag value, the errors are displayed for all WAN PHY ports. The default display is a constantly refreshing real-time display. If you specify the no-refresh parameter, the system displays a snapshot of the data at the time you issue the command.

The tag value may be associated with either a VMAN or a VLAN.
