ATM Address
ATM addresses are used as a means to identify devices and to communicate
between them.
VPI
This software release allows non-standard ATM addresses. This means that
an ATM address may consist of any user-determined arbitrary numerical
designation.
Normally, an ATM address consists of a network prefix, a MAC address and a
selector byte.
[network prefix] [MAC address] [selector byte]
Like traditional LAN packets, ATM cells contain addressing information.
Rather than addressing cells to specific destination devices, ATM cells are
addressed to Virtual Channels (VCs) and Virtual Paths (VPs).
Ensure that the VIP is set to zero (

time.
Specifically, a Virtual Path Identifier (VPI) is a grouping of a number of
Virtual Channels. It consists of the 8-bit number in an ATM cell header which
identifies the specific virtual path that the cell is traversing in the current
physical circuit.
The switch's connection management entity uses VCI and VPI to output
tables. Since the connections in the table are established manually through
network management or remote communications, the channels are called
Permanent Virtual Circuits (PVCs).
