1.3 NB30/LM LOCAL MANAGEMENT FORTHE
CABLETRON SYSTEMS NB30
Cabletron Systems' Local Management provides unique management and
control capabilities for the Cabletron Systems NB30. With Local
Management, you can monitor and fine-tune the operation of your bridge
by isolating network traffic and channeling it to its proper destination. At
the same time, you will improve your network performance.
Local Management provides the necessary management tools for your
NB30 to operate at its full capacity. With Local Management, an NB30
can be managed according to the specific needs of a network manager.
The network manager's ability to set up parameters within Local
Management ensures optimal performance for the NB30, and, hence,
each network.
For example, a network manager can monitor: the flow of traffic through
an NB30, the status of a database, the bridge protocol and port
parameters, and the bridge setup. The number of frames received at the
bridge is recorded as well as a breakdown of the frames’

progress through the bridge, e.g., the frames discarded inbound or the
frames forwarded outbound. A breakdown of errors is provided allowing
the network manager to pinpoint potential problem areas in a network.
Bridge protocol and port parameters, related to the IEEE 802.1d Spanning
TreeAlgorithm, are provided so you can keep track of bridge activity and
cost. Certain parameters can be altered to accommodate a network's
particular requirements.
Local Management for the NB30 provides the network manager with the
necessary control to operate a bridge effectively. For instance, a network
manager can alter bridge setup, e.g., erase a database, disable or restart a
bridge, reset counters, or restore default settings.
If two SPIMs are installed in the NB30, Local Management allows you to
switch the SPIM that is communicating with the network or to set one of
the SPIMs to act as a redundant data path.
When one of the SPIMs is set as a redundant data path, parameters can be
set in Local Management so that the primary path will poll a repeater
module installed in an MMAC. If the repeater module in the MMAC does
not respond within a user defined poll interval and the retry interval is
exceeded, the redundant data path will automatically pick up
communication. This feature ensures that communications between the
local Ethernet Network and an individual NB30 is always maintained.
With a DSX-1 Remote Port module installed in the NB30, you can
configure your T1 link connection and determine the status of the T1 link.
