CHAPTER 1

INTRODUCTION

The TRMM-2 Management Module (see Figure 1-1) can manage two

Token Rings simultaneously and control all Token Ring MIMs within a

Multi Media Access Center (MMAC). Also, it can assign ports to

different rings on port switching MIMs and provide error monitoring of

each ring on which it has an interface – one of which may be external to

the host MMAC. The TRMM-2 is 802.5 and IBM compliant.

INTRODUCTION

1.1 TRMM-2 FUNCTIONAL OVERVIEW

The TRMM-2 offers the following features for the monitoring and control

of Token Ring LANs:

• Complete compatibility with all Token Ring MIMs.

• Ability to assign ports to different rings on port switching MIMs.

• STATION port interface enables a cable connection to a different ring

so that the ring can be managed.

• Full RMON statistical/error network monitoring to track network

performance.

• Ability to act as a Distributed LAN Monitor (DLM) to reduce the

bandwidth needed for network management.

• Cabletron Systems Automatic Beacon Recovery Process (ABRP)

which enables networks to quickly recover from beaconing conditions

automatically.

• Ring Security options that allow you to regulate access to your

networks.

• SNMP compliance.

• Auto-conﬁguration options (at initial power-on or after clearing

NVRAM) that allow you to automatically conﬁgure a collapsed

backbone or two independent Token Rings.

• A power-on Learn Mode that determines and maintains the

conﬁguration of any port switching MIMs in the MMAC hub.

• Runtime IP address discovery that broadcasts BootP requests to obtain

an IP address if one is not assigned to Interface 1.

• Ring Poll Failure Recovery that allows the TRMM-2 to automatically

remove stations that are causing ring poll failures.

1.1.1 Port Assignment

The TRMM-2 can individually assign ports to different rings on port

switching MIMs (e.g., TDRMIM and TRXMIM). This allows users to

insert into one of six different rings.
