Port

The port number.

Admin State

The port administration state. Choosing an administrative state from the drop-down list and clicking Apply changes the port's service state unless network conditions prevent the change. Admin states include:

  • IS-Puts the port in-service. The port service state changes to IS-NR.

  • OOS,DSBLD-Removes the port from service and disables it. The port service state changes to OOS-MA,DSBLD.

  • OOS,MT-Removes the port from service for maintenance. The port service state changes to OOS-MA,MT. For loopbacks, the OOS,MT admin state must be initiated.

  • IS,AINS-Puts the port in automatic in-service. The port service state changes to OOS-AU,AINS.

Service State

An autonomously generated state that gives the overall condition of the port. 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-MA,DSBLD-(Out-of-Service and Management, Disabled) The port is out-of-service and unable to carry traffic.

  • OOS-MA,MT-(Out-of-Service and Management, Maintenance) The port is out-of-service for maintenance. Alarm reporting is suppressed, but traffic is carried and loopbacks are allowed.

  • 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.

Loopback Type

When the port state is set to OOS-MT or OOS-AINS, allows you to provision or clear a terminal or facility loopback on the port.
