Introduction
This chapter provides specific information for the Bridge protocol and how it
operates using the TXPORT MultiPro platform and NMCS software.
Bridge Basics
The MultiPro platform provides intelligent Ethernet switching capabilities via UTP
port. Through the use of dynamic routing tables, the platform learns the location of
specific workstations and servers and then switch Ethernet frames directly to those
locations. Since the MultiPro unit performs as a switch, any LAN protocol using
Ethernet as its base protocol can be transported around a MultiPro network. Unlike
other protocols within the MultiPro platform which can only have one connection
at a time, the LAN port can have multiple, simultaneous connections.
As usual in the MultiPro networking scheme, each LAN port is assigned a name
which other units use to establish their connection to a remote port. Each LAN
port has a remote bridge list which is comparable to the X.25 access table or the
frame relay endpoint list. A connection is established for the port to each of the
remote LANs entered in the remote bridge list.
