Step 4 Click Ring Map.

ID and IP address.
Step 6 Click Close.
2.9.2 Protection Switching, Lock Initiation, and Clearing
The following sections give instructions for port, ring, and span switching and switch-clearing
commands, as well as lock-ons and lockouts.
Initiate a 1+1 Force Switch Command
This procedure switches 1+1 protection group traffic from one port in the group to the other using a
Force switch.
Caution The Force command overrides normal protective switching mechanisms. Applying this command
incorrectly can cause traffic outages.
Caution Traffic is not protected during a Force protection switch.
Note A Force command switches traffic on a working path even if the path has signal degrade (SD) or signal
fail (SF) conditions. A Force switch does not switch traffic on a protect path. A Force switch preempts
a Manual switch.
Step 1 In node view, click the Maintenance > Protection tabs.
Step 2 In the Protection Groups area, select the protection group with the port you want to switch.
Step 3 In the Selected Groups area, select the port belonging to the card you are replacing. You can carry out
this command for the working or protect port. For example, if you need to replace the card with the
Protect/Standby port, click this port.
Step 4 In the Switch Commands area, click Force.
Step 5 Click Yes in the Confirm Force Operation dialog box.
Step 6 If the switch is successful, the group says “Force to working” in the Selected Groups area.
Initiate a 1+1 Manual Switch Command
This procedure switches 1+1 protection group traffic from one port in the group to the other using a
Manual switch.
