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 4
In the Inhibit Switching drop-down list, click

Provisioning a lock-on raises a LOCKON-REQ or an FE-LOCKON condition in CTC. Clearing
the lock on switch request clears these conditions.
