Introduction

This chapter provides an overview of the tasks that may be accomplished using 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

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

• Assign IP address and subnet ma sk.

• Select a default gateway.

• Assign a login password to the device for additional security.

• Download a new firmware image.

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

• Design ate 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 th e number of receive broadcasts that are switched to the other interfaces.

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

• Configure ports to prioritize incoming frames at Layer 2, Layer 3, and Layer 4.

Introduction 1-1

Overview

• Clear NVRAM.

• Set 802.1Q VLAN memberships and port configurations.

• Redirect frames according to port or VLAN and transmit them on a preselected destination port.

• Create a separate Spanning Tree topology for each VLAN configured in the SmartSwitch device.

• Transmit frames on preselected destination ports according to protocol and priority or protocol

and VLAN.

• Configure the switch to operate as a Generic Attribute Registration Protocol (GARP) device to

dynamically create VLANs across a switched network.

• Configure the device to control the rate of network traffic entering and leaving the switch on a

per port/priority basis.

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

• Configure the device to dynamically switch frames according to a characteristic rule and VLAN.

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

• Provide additional security and policy administration capabilities via Port-based Web

Authentication (PWA) by configuring pertinent variables within the LM screen.

• Configure multiple ports to act in an 802.3ad trunk group.

• Configure and manage the use of 802.1w, a standards-based method to rapidly fail over links to

reduce downtime on a network.

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

according to a Classification rule so no other device can be connected to that port and used.

• Configure the device to operate using the path cost values conforming legacy 802.1D or 802.1

standards.

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 statistics or issuing management commands. Local Management provides a wide range
of screens used to monitor and configure the SmartSwitch device.

1-2 Introduction

Navigating Local Management Screens

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.

Out-of-band network management passes data along a medium that is entirely separate from the
common data carrier of the network, for example, a cable connection between a dumb terminal and
a SmartSwitch device COM port. The Enterasys Networks’ 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 de vice even when that device is unable
to communicate through 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 providing terminal emulation services. The Local Manage ment screen cursor responds
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 MANAGEMENT REQUIREMENTS

The SmartSwitch device provides one communication po rt, labeled COM, which supp orts 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.

Introduction 1-3

Local Management Screen Elements

You can also access Local Management using a Telnet connection through one of the network
ports of the SmartSwitch device.

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

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 figure.

Local Management Screen Elements

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 The SAVE command was executed, but nothing was saved to

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

NVRAM because there were no configuration changes since the data
was last saved.

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 screens shown in this guide, the characters in the display
fields are in plain type (not bold). In the field description, the field is identified as being
“read-only”.

Input Fields

Input Fields require the entry of keyboard characters. IP addresses, subnet mask, default gateway
and device time are examples of input fields. In the screens shown in this guide, the characters in
the input fields are in bold type. In the field description, the field is identified as being
“modifiable”.

Selection Fields

Selection fields provide a series of possible values. Only applicable values appear in a selection
field. In the screens shown in this guide, the selections display within brackets and are in bold
type. In the field description, the field is identified as being either “selectab le” when there are mo re
than two possible values, or “toggle” when there are only two possible values.

Introduction 1-5

Local Management Keyboard Conventions

Command Fields
