    INTRODUCTION TO MULTIPLE-RING MMAC This appendix explains the closely related concepts of port switching and the four-ring Flexible Network Bus (FNB). It also compares port switching MIMs with single ring MIMs. The appendix concludes with a sample configuration. A.1 WHY USE MULTIPLE RINGS? Port switching MIMs allow network users to be distributed among many rings.

  • Page 59: Auxiliary Rings

    INTRODUCTION TO MULTIPLE-RING MMAC FUNCTIONALITY A.4.2 Auxiliary Rings Each port switching MIM has two auxiliary rings. These rings never communicate with FNB rings, unless through an external device such as a switch or router. A station on an auxiliary ring can only communicate with stations attached to the same MIM and assigned to the same auxiliary ring.

  • Page 60: A Sample Configuration

    INTRODUCTION TO MULTIPLE-RING MMAC FUNCTIONALITY A.5 A SAMPLE CONFIGURATION The purpose of the port switching family of MIMs is to segment traffic and provide the advantages described in configuration, Figure A-4 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.

  • Page 61: Connections Within The Host Mmac

    Section B.1 CONNECTIONS WITHIN THE HOST MMAC The TRMM-2 can control all Token Ring MIMs within the host MMAC. For instance, it can assign ports to different rings, enable or disable ports, or configure ports for RO use, even if the STATION port interface is not attached.

  • Page 62: Connections To Single Ring Mims

    Although all ports on single ring MIMs are dedicated to FNB Ring 1, these MIMs may segment the FNB to create rings which are isolated from the TRMM-2’s FNB interface connection. The STATION port interface can then provide a connection between the TRMM-2 and any isolated ring. See Figure B-1 connections to single ring MIMs.

  • Page 64: Connections Outside The Host Mmac

    There are no restrictions regarding the insertion of the STATION port interface into any ring outside the host MMAC. When the STATION port interface is connected to an external ring, the TRMM-2 performs RMON, Ring Security, and general statistical reporting functions on the ring, but does not provide concentrator-specific information (e.g., Ports Enable).
