DLP-G181 Apply a Lock-On
Note You can apply the Lock On command only to the working/active card or port. If the working card or port
is standby (traffic is switched), the Lock Out button is not available.
Step 1 In node view, click the Maintenance > Protection tabs.
Step 2 In the Protection Groups area, click the protection group that contains the card (Y-cable) or port (splitter)
that you want to lock on.
Step 3 In the Selected Group area, click the working/active card.
Step 4 In the Inhibit Switching drop-down list, click Lock On.
Step 5 Click Yes in the confirmation dialog box.
The lock-on has been applied. Traffic cannot switch to the protect card. To clear the lock-on, see the
“DLP-G183 Clear a Lock-On or Lockout” task on page 10-38.
Note Provisioning a lock-on raises a LOCKON-REQ or an FE-LOCKON condition in CTC. Clearing
the lock on switch request clears these conditions.
Step 6 Return to your originating procedure (NTP).

card in a Y-cable protection group or port in a splitter protection group.
