Cisco Systems D200 Manual De Usuario

To apply a lock-on to a protect card in a 1:1 or 1:N protection group, the protect card must be active. If 
the protect card is in standby, the Lock On button is disabled. To make the protect card active, you must 
switch traffic from the working card to the protect card (

). When the protect card is active, you can 

apply the lock-on.

Use the following rules to determine if you can apply a lock-on:

For a 1:1 electrical protection group, the working or protect cards can be placed in the Lock On state.

For a 1:N electrical protection group, the working or protect cards can be placed in the Lock On 
state.

For a 1+1 optical protection group, only the working port can be placed in the Lock On state.

In node view, click the Maintenance > Protection tabs.

In the Protection Groups list, click the protection group where you want to apply the Lock On state.

If you determine that the protect card is in standby mode and you want to apply the Lock On state to the 
protect card, make the protect card active:

In the Selected Group list, click the protect card.

In the Switch Commands area, click Force.

In the Selected Group list, click the active card where you want to lock traffic.

In the Inhibit Switching area, click Lock On.

Click Yes in the confirmation dialog box.

This task prevents traffic from being switched from one card to another.
