CHAPTER 1
INTRODUCTION
The TRMM-4 Management Module (see Figure 1-1) can manage four
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. The TRMM-4 is 802.5 and IBM
compliant.

1.1 TRMM-4 FUNCTIONAL OVERVIEW
The TRMM-4 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.
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 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-4 to automatically
remove stations that are causing ring poll failures.
1.1.1 Port Assignment
The TRMM-4 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.
