Welcome to the Cabletron Systems MMAC-Plus™ Remote Management for the
9A128-01™ User’s Guide. We have designed this document to serve as a simple
reference guide for using MMAC-Plus Remote Management for the 9A128-01
FDDI/ATM bridge module. You should read through this guide to fully
understand SPECTRUM Element Manager remote management for the 9A128-01.
The 9A128-01 ATM Access Module provides two bridging interfaces which allow
you to connect an external ATM network to either one of the two FDDI networks
resident on the MMAC-Plus hub’s FNB backplane. External front panel
connections are made via a SONET, OC3 ATM interface. The 9A128-01 can be
used to aggregate FNB traffic to an ATM backbone, or provide connectivity
between ATM workstations and traditional LAN users. The 9A128-01 is an 802.3
LAN Emulation Client (LEC) device and will operate in an 802.3 emulated LAN;
see Chapter 6, LEC Administrator, in your SPECTRUM Element Manager Tools
Guide for more information.
IETF RFC 1483 — Multi-Protocol Encapsulation over ATM Adaptation Layer 5 —
specifies a number of methods for encapsulating LAN traffic for transmission
over ATM networks. Current versions of the 9A128-01 firmware use 802.3
VC-based multiplexing for bridging protocols; the most recent version of
firmware (2.10.13) supports ATM Forum LAN Emulation and UNI 3.0/3.1 SVC
signaling; future version will add support for Cabletron’s SecureFast Switching.
Using This Guide
