INTRODUCTION TO MULTIPLE-RING MMAC FUNCTIONALITY
A-6
A.5 A SAMPLE CONFIGURATION
The purpose of the port switching family of MIMs is to segment traffic
and provide the advantages described in
Section A.1 . As an example
configuration, Figure A-4 shows an MMAC configured with multiple
rings. The users of each ring typically share a server. One of these user
groups is attached to a MAU that is connected to a TRXMIM port that has
been configured as a RO port. The switch provides the communication
among rings.
