Description
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.
