Introduction

This chapter provid es an ov ervie w of the tasks that may be ac complished usin g Local Management
(LM), and an introduction to LM screen navigation, in-band and out-of-band network
management, screen elements, and LM keyboard conventions.

Important Notice

Depending on the firmware version used in the SmartSwitch device, some features described in
this document may not be supported. Refer to the Release Notes shipped with the SmartSwitch
device to determine which features are supported.

1.1 OVERVIEW

Local Management is a management tool that allows a network manager to perform the following
tasks:

• Select the operational mode of the device.

• Assign IP address and subnet mask.

• Select a def au lt gateway.

• Control access by establishing community names.

• Download a new firmware image.

• Upload or download a configuration file to or from a TFTP server.

• Designate which Network Management Workstations receive SNMP traps from the device.

• View switch, interface, and RMON statistics.

• Assign ports to operate in the standard or full duplex mode.

• Configure ports to perform load sharing using SmartTrunking. Refer to the SmartTrunk User’s

Guide for details.

• Control the number of receive broadcasts that are switched to the other interfaces.

Introduction 1-1

Overview

• Set flow control on a port-by-port basis.

• Configure ports to prioritize incoming frames.

• Clear NVRAM.

• Set 802.1Q VLAN memberships and port configurations.

• Redirect f rames accor ding to por t or VLAN and tra nsmit them on a presele cted dest ination p ort.

• T r ansmit frames on preselected destination port s according to protocol and priority or protocol

and VLAN.

• Conf i gure the swi tc h to ope rate as a Generic Attribute Registration Protocol (GARP) device to

dynamically create VLANs across a switched network.

• Conf igure the devic e to cont rol the ra te of tra ff ic from/ to the netw ork on a per port/p riority ba sis.

• Configure an optional HSIM or VHSIM installed in the device.

• Conf igure the de vice to dynamically swi tch frames according t o a characterist ic rule and VLAN.

• Configure ports on the SmartSwitch device as Router Redundancy Protocol (VRRP) ports.

• Provide additional security by configuring a physical port to lock on an attached device

according to a classification rule so that no other device can be used on that port.

There are three ways to access Local Management:

• Locally using a VT type terminal connected to the COM port.

• Remotely using a VT type terminal connected through a modem.

• In-band through a Telnet connection.

1.1.1 The Management Agent

The management agent is a process within the SmartSwitch device that collects statistical
information (e.g., frames received, errors detected) about the operational performance of the
managed network. Local Management communicates with the management agent for the purpose
of viewing statist ics or iss uing man agement commands . Local Management pro vide s a wid e rang e
of screens used to monitor and configure the SmartSwitch device.

1.1.2 In-Band vs. Out-of-Band

Network management systems are often classified as either in-band or out-of-band. In-band
network management passes data along the same medium (cables, frequencies) used by all other
stations on the network.

1-2 Introduction

Navigating Local Management Screens

Out-of-band network management passes data along a medium that is entirely separate from the
common data carrier of the netw ork, for e xample, a cable connectio n between a dumb terminal and
a SmartSwitch device COM port. Cabletron Systems Local Management is an out-of-band
network management system.

A device connected out-of-band to the management agent is not connected to the LAN. This type
of connection allows you to communicate with a network device even when that device is unable
to communi cate throug h the network , for example, at the time of installation.

1.2 NAVIGATING LOCAL MANAGEMENT SCREENS

To navigate within a Local Management screen, use the arrow keys of the terminal or the
workstation pr ovidi ng terminal e mulation s ervices. The Loc al Management screen curs or respond s
to the LEFT, RIGHT, UP, and DOWN arrow keys. Each time you press an arrow key, the Local
Management screen cursor moves to the next available field in the direction of the arrow key.

The Local Management screen cursor only moves to fields that can be selected or used for input.
This means that the cursor jumps over display fields and empty lines on the Local Management
screen.

The Local Management screen cursor provides wrap-around operation. This means that a cursor

located at the edge of a screen, when moved in the direction of that edge, “wraps around” to the
outermost selectable item on the opposite side of the screen which is on the same line or column.

1.3 LOCAL MANAGEM ENT REQUIREMEN TS

The SmartSwitch device provides one communication port, labeled COM, which supports a
management terminal connection. To access Local Management, connect one of the following
systems to the COM port:

• Digital Equipment Corporation VT series terminal.

• VT type terminal running emulation programs for the Digital Equipment Corporation

VT series.

• IBM or compatible PC running a VT series emulation software package.
You can also access Local Management using a Telnet connection through one of the network

ports of the SmartSwitch device.

NOTE: For details on how to connect a console to the SmartSwitch, the setup
parameters for the console, or how to make a telnet connection, refer to Chapter 2.

Local Management Screen Elements

1.4 LOCAL MANAGEMENT SCREEN ELEMENTS

There are six types of screens used in Local Management: password, menu, statistics,
configuration, status, and warning screens. Each type of screen can consist of one to five basic
elements, or fields. Figure 1-1 shows an example of the fields in a screen. A description of each
field follows the figur e.

NOTE: The following definitions apply to most of the Local Management screens.
Exceptions to these definitions may occur in the Local Management screens of some
devices.

The following list explains each of the Local Management fields:

Event Message Field

This field briefly displays messages that indicate if a Local Management procedure was executed
correctly or incorrectly, that changes were saved or not saved to Non-Volatile Random Access
Memory (NVRAM), or that a user did not have access privileges to an application.

Table 1-1 describes the most common event messages. Event messages related to specific Local

Management applications are described with those applications throughout this manual.

Table 1-1 Event Messages

Message What it Means

SAVED OK One or more fields were modified, and saved to NVRAM.
NOT

SAVED--PRESS
SAVE TO KEEP
CHANGES

NOTHING TO
SAVE

Attempting to exit the LM screen after one or more fiel ds were
modified, but not saved to NVRAM.

The SAVE command was e x ecut ed, b ut nothi ng was sa v ed to NVRAM
because there were no configuration changes since the data was last
saved.

Heading Field

Indicates the model of the device.

Display Fields

Display fields cannot be edited. These fields may display information that never changes, or
information that may change as a result of Local Management operations, user selections, or
network monitoring information. In the sc reens shown in this guide, the cha racters in the display
fields are in plain type (not bold). In the field description, the field is identified as being

“read-only”.
