1.3 NB30/LM LOCAL MANAGEMENT FOR THE

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

Tree Algorithm, 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.

CHAPTER 3

USING LOCAL MANAGEMENT

FOR THE 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.

SW Version (Software):

Displays the release version of the ﬁrmware installed in the NB30.

USING LOCAL MANAGEMENT

3-2

HW Version (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 GENERAL TIPS

• 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 MENU TREE

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.
