Configuring Fault-tolerant PVCs

Use the following sequence to configure fault-tolerant PVCs:

Step 1. Follow the sequence beginning on page 3-4 to define a UNI DCE or UNI DTE

logical port as a backup port. In the General tab of the Add Logical Port dialog

box, select the check box for the Backup Service Name field (see page 3-18).

Step 2. Define and specify a Service Name that will be bound to the primary port (see

page 14-4).

Step 3. Configure circuits to use the Service Name as an endpoint (see page 10-14). Note

that both endpoints can be different Service Names.

Step 4. Define one or more backup logical ports (of the same type as the primary logical

port). When defining General Attributes for the backup logical port, select the

check box for the Backup Service Name field (see page 3-18).

Step 5. (Optional) Activate one of the backup logical ports, as needed (see “Activating a

Backup Binding Port” on page 14-6).

Note – Lucent recommends that you avoid configuring SVCs on a logical port that is

also designated as a backup port in a fault-tolerant PVC configuration.

Note – You cannot use redirect PVCs with resilient UNI/NNI.
