Description

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:

  • unlocked: Puts the port in-service. The port service state changes to unlocked-enabled.

  • unlocked,automaticInService: Puts the port in automatic in-service. The port service state changes to unlocked-disabled,automaticInService.

  • locked-disabled: Removes the port from service and disables it. The port service state changes to locked-enabled,disabled.

  • locked,maintenance: Removes the port from service for maintenance. The port service state changes to locked-enabled,maintenance.

Service State

An autonomously generated state that gives the overall condition of the port. Service states appear in the format: Administrative State-Operational State, Status Attribute. Port service states include:

  • unlocked-enabled: The port is fully operational and performing as provisioned.

  • unlocked-disabled,automaticInService: 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 unlocked-disabled,automaticInService state for the duration of the soak period. After the soak period ends, the port service state changes to unlocked-enabled.

  • locked-enabled,disabled: The port is out-of-service and unable to carry traffic.

  • locked-enabled,maintenance: The port is out-of-service for maintenance. Alarm reporting is suppressed, but traffic is carried and loopbacks are allowed.
