Description

Port

Displays the slot and port where the LDCC is provisioned.

OSPF Disabled on Link

Indicates whether Open Shortest Path First (OSPF) is disabled on the link. OSPF should be disabled only when the slot and port connect to third-party equipment that does not support OSPF.

Port Service State

Indicates the LDCC port state. Service states appear in the format: Primary State-Primary State Qualifier, Secondary State. Port service states include:

  • OOS-AU,AINS-(Out-Of-Service and Autonomous, Automatic In-Service) The port is out-of-service, but traffic is carried. Alarm reporting is suppressed.

After the soak period ends, the port service state changes to IS-NR.
