Possible Cause

The cross-connect configuration at the far-end NE does not match the cross-connect configuration at the local NE.

Default Severity

Critical

Service Affecting

Yes (true).

Clearing a PyldMism Alarm

Note

Follow all applicable safety requirements as described in the BTI7800 Series Hardware Overview and Installation Guide.

  1. Retrieve interface data to compare the values of the Payload Type and Received Payload Type parameters.
    show interface name:identifier
  2. Retrieve cross-connect information for the local NE and the far-end NE to determine at which end the cross-connect is incorrectly provisioned.
    show cross-connect
  3. Delete the correct cross-connect, and reprovision it to resolve the mismatch. For information, see the BTI7800 Series Software Configuration Guide.
  4. Check for alarms on the local interface.
    • If the alarm has cleared, you have completed this procedure.

    • If the alarm does not clear, contact your next level of support.
