Multiple PVCs

Of the two methods, having multiple PVCs per service record uses network

addressing most efficiently and is the easiest to configure.

Upper-layer protocols treat each service record on an ATM network interface as a

single access point. These protocols use a single network address to send all traffic

destined for the network to the ATM network interface. Figure B-3

shows a

conceptual drawing of multiple PVCs accessing an ATM network through one

service record.

Figure B-3. Multiple PVCs per Service Record

Although you need to configure each PVC manually, you need only define and

associate protocols with the ATM network service record. All the PVCs that you

configure for a given ATM service record carry the protocols that you select and

configure to run on that service record.

Note:

When you configure multiple PVCs per service record, the PVCs all use

the data encapsulation type that you set for the ATM service record (that is, the

value of the Data Encapsulation Type parameter set in the ATM Service

Records List window). Refer to “Data Encapsulation,” earlier in this chapter,

for more information.
