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.
