Welcome to the Cabletron SystemsÕ
SPECTRUM
¨
Element Manager
Bridge/Router Interface (BRIM) UserÕs Guide
. We have designed this guide
to serve as a reference for using SPECTRUM Element Manager for all types
of BRIMs.
Cabletron SystemsÕ Bridge/Router Interface Modules (BRIMs) provide ßexible,
integrated bridging functionality (including trafÞc Þltering by destination, source,
type Þeld, and 64-byte data offset, and support for the Spanning Tree Algorithm)
or routing functionality to the network hub. By accommodating several media
types and topologies, these network interfaces connect to any standard Local Area
Network (LAN) or Wide Area Network (WAN).
Since BRIMs plug into CabletronÕs Intel i960-based products (e.g., EMM-E6,
ESXMIM, MicroMMAC, and MicroMMAC-T), SPECTRUM Element Manager
views the hub and bridge/router as a single entity. The following BRIMs are
supported by SPECTRUM Element Manager:
BRIM-A6
The ATM Bridge/Router Interface Modules feature high
BRIM-A6DP
speed ATM connectivity (at rates up to 155 Mbps). They
are fully compatible with the 9A000 ATM Switch Module
for the SmartSwitch
¨
9000, and Fore SystemsÕ ASX-200.
They support the IETF AToM MIB, Multi-Protocol
Encapsulation over AAL5, and many other protocols,
and meet ATM Forum UNI speciÞcations. The BRIM-A6
supports a single ATM interface, and the BRIM-A6DP
supports two redundant ATM interfaces.
BRIM-E6
The Ethernet BRIM has a user-conÞgurable Ethernet Port
Interface Module (EPIM) port that provides media
ßexibility for AUI, UTP, STP, Þber or coax cable.
