Description

Port

Displays the slot and port where the SDCC 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 SDCC port service state. Service states appear in the format: Primary State-Primary State Qualifier, Secondary State. Port service states include:

  • IS-NR-(In-Service and Normal) The port is fully operational and performing as provisioned.

  • 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. The ONS node monitors the ports for an error-free signal. After an error-free signal is detected, the port stays in OOS-AU,AINS state for the duration of the soak period. After the soak period ends, the port service state changes to IS-NR.

  • OOS-MA,DSBLD-(Out-of-Service and Management, Disabled) The port is out-of-service and unable to carry traffic.
