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:
unlocked-enabled-The port is fully operational and performing as
provisioned.
unlocked-enabled,disabled-The port is out-of-service and unable to carry
traffic.
unlocked-enabled,maintenance-The port is out-of-service for maintenance.
Alarm reporting is suppressed, but traffic is carried and loopbacks are allowed.
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.
