bridging capabilities. It provides port level control and statistics for
CabletronÕs Token Ring Bridging Media Interface Modules. It is fully IBM
Token Ring compatible and IEEE 802.5 compliant, using an Intel i960 RISC
processor for in-depth management functions. The module is designed to be
installed in a mid-chassis slot of a Cabletron Systems MMACª (Multi-Media
Access Center¨), constituting a two-port bridge that connects to one LAN
segment via the FNB¨ (Flexible Network Busª) and to another LAN
segment via a station port accessed on the TRBMIMÕs front panel.
A second-generation TRBMIM (CabletronÕs Dot5 Architecture, available on
Þrmware version 2.00 or higher) also is capable of ring management, as well
as providing intelligence to the hub. This capability is available as a switch-
selectable mode determined by the setting of hardware switch (S2 in Bank 1,
SW1) on the TRBMIM unit. To change modes, you must remove the unit from
the system, set the switch to its desired position, and then reinstall the unit in
its MMAC slot; the Þrmware will then set the card to the desired mode when
the card is rebooted. If the switch is
ON
, or in the up position, the device boots
up for the Bridging-Only mode, and the TRBMIM unit will be the only thing
that appears in the SPECTRUM Device View. If the switch is
OFF
, or in the
down position, the device boots up in the Bridging and Management mode,
and the SPECTRUM Device View will also include the hub and associated
devices.
SPECTRUM management of the TRBMIM is based on the following
Management Information Bases (MIBs), which come as part of the software
module for the model type:
¥ Cabletron Dot5 MIB
¥ Cabletron Bridging MIB
¥ IETF Bridging MIB
¥ Cabletron Token Ring FNB MIB
¥ Cabletron DownLoad MIB
¥ Internet MIB-II (RFC 1213)
¥ Cabletron Chassis MIB
The following chapters explain how you use SPECTRUM and the
management module software to monitor your TRBMIM.
TRBMIM Applications
The TRBMIM management module supports both common and device-speciÞc
applications described in the
MIB II Applications, Bridging Applications,
and Miscellaneous Applications
references. SPECTRUM management of a
TRBMIM is based on the following common and device-speciÞc applications:
¥ Bridging (Gen_Bridge_App)
- Spanning Tree (Span_Tree_App)
- Spource Routing (Source_Rt_App
