10 In the Slot/Group/Port field, select a radio interface, Radio Protection group, Multi-Carrier ABC group, or
cascading interface to serve as the interface for the protecting trail.
Note
Some interfaces may not appear in the Slot/Group/Port field. Refer to
Endpoints for the possible reasons an interface will not appear. If there are no available interfaces, a
message appears that no endpoint can be selected.
11 In the VC field, select the VC you want to classify to the endpoint of the protecting trail (1-512).
12 In the Protecting Trail ID or Working Trail ID field, select a Trail ID (1-512) to identify the protecting or
working trail. Only unused Trail ID values appear in the selection box. The default value is the lowest unused
Trail ID. All nodes in the protected configuration, both on the protected and the protecting path, must have
the same Protecting Trail ID or Working Trail ID.
13 Click Finish. The Selection Summary page opens, displaying the parameters you have configured.
