Point-to-Multipoint PVCs

Instructions in this section describe how to set up a point-to-multipoint connection through your SmartSwitch 9A100.
Example: Create a point-to-multipoint connection between a broadcasting workstation on port A1 and three other
workstations connected to ports B2, B3, and C1.
1. Use

the other for the backward direction. For this example, for the forward traffic descriptor, we select
UBR and accept the defaults.

However, on a point-to-multipoint connection there should be no traffic in the backward direction, so we define the
backward traffic descriptor with its Cell Loss Priorities set to zero (0).

In the example above, traffic descriptor six (6) will be used in the forward direction, and traffic descriptor seven (7)
will be used in the backward direction.
