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’

INTRODUCTION
1-3
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.

CHAPTER 2
GETTING STARTED
This chapter lists procedures for accessing Local Management for the
NB30. Information is provided on the necessary terminal and cable
configurations for connecting a terminal to the console port on the NB30,
as well as instructions for entering the password.
2.1 TERMINAL CONFIGURATION
Local Management for the NB30 is accessed through a VT™ 200 or 300
series or a PRIME™ 200 series terminal, or terminals running emulation
programs for these series of terminals. The terminal or emulating terminal
is attached to the port labeled CONSOLE on the bridge.
For instructions on setting up your terminal and the keyboard map, refer
to your terminal manual.
The terminal configurations must be set as follows, so that the terminal
can communicate with Local Management for the NB30.

2.2 CABLE CONFIGURATION
Local Management is accessed by an RS232 cable available from
Cabletron Systems. This cable connects the terminal to the bridge's
Console port.
The pin out for a cable with a 25 pin or a 9 pin connector at the terminal
end of the cable, and a 9 pin connector at the bridge end of the cable,
should be configured as shown in Section 2.2.1 or 2.2.2.

Cabletron Systems, is being used to connect the terminal to the Bridge.
To access Local Management, follow the procedure below:
1. Plug the 9 pin end of the RS232 cable into the RS232 port labeled
CONSOLE on the bridge.
2. Plug the 25 pin end of the RS232 cable into the COMM port on the
terminal.
3. Turn the terminal on. The Terminal Type Menu Screen, Figure 2-1,
will appear, prompting you to select the terminal type.

USING LOCAL MANAGEMENT
FORTHE NB30
This chapter explains how to move around Local Management for the
NB30. Local Management's screens can be easily accessed by
manipulating the arrow keys on your terminal.A menu tree of the
software is provided for your convenience. Refer to this illustration until
you are familiar with the organization of the screens.
3.1 GENERAL SCREEN INFORMATION
Similar descriptive Information is displayed in the upper portion of all
Local Management for the NB30 screens.A list of these common fields is
provided here for your convenience.
Network Address:
Displays the Ethernet address of the bridge in a hexadecimal format
(XX-XX-XX-XX-XX-XX).
Bridge Name:
Displays the user-defined name (up to 32 characters available) if one has
been assigned to the bridge. The default name is
CABLETRON REMOTE BRIDGE.
Location:
Displays the user-defined name (up to 14 characters available) to indicate
the location of the bridge on the network. The default name is LOCAL.
Uptime:
Displays the time period (in Days, Hours, Minutes format) that has
elapsed since the bridge was last reset or initialized.
Type:
Indicates the type of bridge, e.g. NB30.
SWVersion (Software):
Displays the release version of the firmware installed in the NB30.

USING LOCAL MANAGEMENT
3-2
HWVersion (Hardware):
Displays the revision number of the mother board of the bridge.
Status:
Indicates the status of the bridge, e.g., ON-LINE, STAND BY, or
DISABLED.
3.2 GENERALTIPS
• Use the arrow keys to move the cursor up, down, left, or right on the
screen to select fields or options.
• The TAB key performs the same function as the right arrow key.
• At the bottom of most screens, you can return to the previous screen
by selecting the Return option.
3.3 LOCAL MANAGEMENT MENUTREE
The Bridge Information Screen is at the top of the Local Management for
the NB30 menu tree. All the screens that manage and control the bridge
are accessed through this screen. From the Bridge Information Screen, the
menu branches out. For instance, there are six options available at the
Bridge Information Screen. Four of these options - Setup, Port Counters,
Filtering Database, and Bridge Protocol - lead to additional screens.
These screens move from general to more specific. For example, from the
Filtering Database Screen, you can view the total number of entries in the
Acquired or Permanent databases. Then, by selecting the Display Entry
option at the bottom of the Filtering Database Screen, you can view
individual entries. As you can see, the further you move down the menu
tree, the more specific the diagnostic functions become. This menu tree is
provided to assist you while moving through Local Management for the
NB30. Refer to this illustration to locate your position on the menu tree.
