Preface

This guide contains instructions on how to use the AT-S81 management software to manage and monitor the AT+8000/8POE Fast Ethernet switch.
The AT-S81 management software has three management interfaces: menus, web browser, and CLI. You access the menus and CLI interfaces through the console port on the switch or through Telnet, and the web browser interface from any management workstation on your network that has a web browser application. For background information on the management interfaces, refer to Chapter 1, “Overview” on page 17.
Note
The AT-S81 CLI interface is described in the AT-S81 Management Software Command Line Interface User’s Guide.

Chapter 1

Overview

This chapter provides an overview of the AT-S81 management software for the AT-8000/8POE Fast Ethernet switch. This chapter describes the different methods for accessing the software and the management access levels. This chapter contains the following sections:
“Management Overview” on page 18
“Local Connection” on page 19
“Remote Connection” on page 20
“Management Access Level” on page 21

Chapter 1: Overview

Management Overview

The AT-S81 management software allows you to view and adjust the operating parameters of the AT-8000/8POE Fast Ethernet switch. Here are a few examples of the functions that you can perform with the management software:
Enable and disable ports
Configure a port’s speed and duplex mode
Create port trunks
Configure a port mirror
Configure Quality of Service (QoS)
Create and tagged virtual LANs
Configure 802.1x network access control
The AT-S81 management software is preinstalled on the switch with default settings for all of the switch’s operating parameters. You do not have to manage the switch if the default settings are adequate for your network. Instead, you can use the device as an unmanaged switch by connecting it to your network, as explained in the hardware installation guide, and powering on the unit.
Note
The default settings for the management software are listed in Appendix A, “AT-S81 Software Default Settings” on page 283.
To actively manage the switch and adjust its operating parameters, you must connect to an AT-8000/8POE Fast Ethernet switch and access the switch’s AT-S81 management software. There are two ways to connect to the switch:
Locally
Remotely
Depending upon the method you choose, specific AT-S81 software interfaces are available. When you have a local connection, you can use the menus (described in Section I of this guide) or the command line interface (CLI) (described in Section III). With a remote connection you can use the menus, CLI, and web browser interfaces, or a third-party network management application. (The web browser interface is described in Section II).
The following sections in this chapter briefly describe each type of management session.

Local Connection

AT-S81 Management Software User’s Guide
To establish a local connection with a switch, you connect a terminal or a PC with a terminal emulator program to the terminal port on the front of the switch using the management cable included with the unit. This type of connection is referred to as “local” because you must be physically close to the switch, such as in the wiring closet where the switch is located.
Note
For instructions on how to start a local management session, refer to “Starting a Local Management Session” on page 26.
With a local connection, you can manage the switch using the menus or CLI.
A switch does not need an Internet Protocol (IP) address for you to manage it locally. You can start a local management session on a switch at any time. It does not interfere with the forwarding of network packets by the device.

Chapter 1: Overview

Remote Connection

You can use any management station on your network that has the Telnet application to manage an AT-8000/8POE Fast Ethernet switch. This is referred to as a remote connection. A remote connection allows you to use any of the AT-S81 software user interfaces: menus, CLI, web browser, or SNMP.
In order for you to manage a switch using the web browser interface, the switch must have an IP address and subnet mask. To manually assign an IP address, refer to “Configuring the IP Address, Subnet Mask, and Gateway Address” on page 32. To configure the switch to obtain its IP configuration from a DHCP server, refer to “Enabling and Disabling the DHCP Client” on page 35. The initial assignment of an IP address must be made through a local management session.
For instructions on how to start a remote management session to use the web browser interface, refer to “Establishing a Remote Connection to Use the Web Browser Interface” on page 188.

Application
Note
In order to remotely manage a switch using a web browser, the remote management station must be a member of the switch’s Default VLAN. The switch processes remote management packets only when they are received on an untagged port of the Default VLAN.
You can use the Simple Network Management Protocol (SNMP) to run a network management application such as AT-View to manage the switch through a remote connection. A familiarity with how to use management information base (MIB) objects is necessary for this type of management.
The AT-S81 management software supports the following MIBs:
SNMP MIB-II (RFC 1213)
Bridge MIB (RFC 1493)
Remote Network MIB (RFC 1757)
Allied Telesyn managed switch MIB
You must download the Allied Telesyn managed switch MIB (atiswitch.mib) file from the Allied Telesyn web site and compile the files with your SNMP application. For compilation instructions, refer to your third-party application’s documentation. Refer to Chapter 5, “SNMP” on page 63 for information about how to configure SNMP on the switch.

Management Access Level

The AT-S81 management software has one level of management access: manager. When you log in as a manager, you can view and configure all of a switch’s operating parameters. You log in as a manager by entering the appropriate username and password when you start an AT-S81 management session. The default username and password are both “manager”.

Getting Started with the Menus Interface

This chapter provides information and instructions on how to access the menus interface of the AT-S81 management software by starting a local management session. This chapter contains the following sections:
“Starting a Local Management Session” on page 26
“Using the Menus Interface” on page 28
“Quitting from a Local Management Session” on page 29
Section I: Using the Menus Interface 25
Chapter 2: Getting Started with the Menus Interface

Starting a Local Management Session

You establish a local management session with the AT-8000/8POE switch by connecting a terminal or personal computer with a terminal emulation program to the RS-232 console port on the front panel of the switch.
Note
You do not need to assign an IP address to the switch to manage the unit from a local management session.
To start a local management session, perform the following procedure:
1. Connect one end of the management cable included with the switch to the console port on the AT-8000/8POE switch, as shown in Figure 1.

2. Connect the other end of the cable to the RS-232 port on a terminal or PC with a terminal emulator program.
3. Configure the terminal or terminal emulator program as follows:
Baud per second: 9600
Data bits: 8
Stop bits: 1
Flow control: None
Note
These settings are for a DEC VT100 or ANSI terminal, or an equivalent terminal emulation program. You cannot change this.

28 Section I: Using the Menus Interface

Quitting from a Local Management Session

To quit a local management session, return to the Main Menu and type Q for Quit. When you are finished managing the switch, make sure to exit from a management session. Quitting from a local session prevents unauthorized changes to the switch’s configuration if you leave your workstation unattended.
Note
A local management session automatically times out if there is no management activity during a pre-defined length of time referred to as the timeout period. The timeout feature is intended to protect the parameter settings on the switch from unauthorized changes should you leave your management station unattended during a management session. The default timeout value is 10 minutes. To change the timeout default value, refer to “Setting the User Interface Configuration” on page 38.
