Point-To-Multipoint Pvcs - Cabletron Systems SmartSwitch 6500 User Manual

PVC Connections
For this example, we specify CBR as the traffic type, then take the remaining defaults. Enter the
command to obtain the index number of the new traffic descriptor. In this example, the index
trafficdescriptor
number is two (2).

The example above creates a PVC between ports 7a1 and 7b2 with VPCI/VCI = 0/100.
3. Plug the end nodes into the specified SmartSwitch 6500 ports (7a1 and 7b2).
Configure each end node with the proper IP address, subnet mask, and VPCI/VCI pair = 0/100.
4.
The end nodes can communicate with each other through the point-to-point PVC connection.

Point-to-Multipoint PVCs

Instructions in this section describe how to set up a point-to-multipoint connection through your SmartSwitch 6500.
Example: Create a point-to-multipoint connection between a broadcasting workstation on port 7a1 and three other
workstations connected to ports 7a2, 7a3, and 7a4.
