Port
Displays the port number.
Admin State
Sets the port administration state. Choose an administrative state from the drop-down list and click Apply to change the port 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.
Note
CTC will not allow you to change a port service state from IS-NR to OOS-MA,DSBLD. You must first change a port to the OOS-MA,MT service state before putting it in the OOS-MA,DSBLD service state.
Service State
Shows 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. For additional state information, see States.
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.
Inhibit FE Lbk
