TCX1000-RDM20 Port Administrative States


Port Administrative State and Operational State

The ports on the TCX1000-RDM20 have two possible states:

  • Operational — The operational state is read-only and can be either Up, to indicate the port is operational, or Down, to indicate the port is not operational.

  • Administrative — The administrative state is configurable and can be set to In-service or Out-of-service.


To enable a link, set the administrative state of the port to In-service.

Placing a port Out-of-service automatically blocks all associated spectrum. It does not change any of the provisioned configuration parameters so that the connection automatically returns to the same state it was in when placed back to In-service, providing external conditions remain the same as well. An Out-of-service port continues to accept provisioning changes but will not optically apply any of them until it is placed back into service.

Input and output ports are initially specified during connection creation but can be also be changed at any time. This can be done without restriction, whether the connection is in or out-of-service and whether it is blocked or unblocked.

Auto Provisioning of Ports

By default, the following ports are set to Out-of-service on a new device:

  • Line ports — When you define an external link for the line port, the administrative state on both the line port and the OSC 0 port are auto-provisioned to In-service.

  • Universal ports — When you create a physical-link to a multiplexer-demultiplexer or to a Junos port, the universal port is auto-provisioned to In-service.

  • OSC ports — Auto-provisioning of these ports works in the following manner:

    • The OSC port is the pluggable port and after the supplied optical SFP transceiver is plugged in, the administrative state is automatically changed to In-service.
