Introduction
This chapter describes the ONline™ Ethernet Bridge Module basic
capabilities, operation, and system configuration alternatives. The ONline
Ethernet Bridge Module is referenced throughout this manual as the Bridge
Module.
The Bridge Module
The Bridge Module is a high-performance bridge that transparently
interconnects your facility-wide Ethernet and IEEE 802.3 networks to form a
single extended LAN. The Bridge Module fits into your ONline System
Concentrator unit using only two slots and allows you to perform the
following functions:
❑ Interconnect Ethernet and IEEE 802.3 subnetworks
❑ Isolate local traffic on subnetworks through dynamic and permanent
packet filtering
❑ Configure redundant LAN interconnection by using the IEEE 802.1(d)
