Console Commands
You can create either a PTP (point-to-point) or PMP (point-to-multipoint) PVC
when you define the ports and low identifiers [vci] and [vpi]. To send traffic from
one port to multiple ports, enter the same low port and low identifiers for all the
PVCs at a single port. Then, for each PVC from that single incoming port, enter
unique high ports and high identifiers. PTP PVCs must have unique low and high
ports and identifiers. A PMP connection is used when you want to multicast
(restrict broadcasting) from a single point (root) to multiple points (leaves).
Leaves could be home computers receiving and simultaneously viewing a single
video program.
