Chapter 1: Switch Management

Configuration Options

For advanced management capability, the SNMP/RMON Module provides a

menu-driven system configuration program. This program can be accessed by a

direct or modem connection to the serial port on the rear panel (out-of-band), or by a

Telnet connection over the network (in-band).

The management agent is based on SNMP (Simple Network Management

Protocol). This SNMP agent permits the switch to be managed from any PC in the

network using in-band management software (such as Accton’s AccView).

The management agent also includes an embedded HTTP Web agent. This Web

agent can be accessed using a standard Web browser from any computer attached

to the network.

The system configuration program and the SNMP agent support management

functions such as:

• Enable/disable any port

• Set the communication mode for any port

• Configure SNMP parameters

• Configure VLANs or multicast filtering

• Display system information or statistics

• Configure the switch to join a Spanning Tree

• Download system firmware

• Restart the system

Required Connections

Console Port (Out-of-Band) Connections

Attach a VT100 compatible terminal or a PC running a terminal emulation program

to the serial port on the switch’s rear panel. Use the null-modem cable provided with

this package, or use a null modem connection that complies with the wiring

assignments shown in Appendix B of this guide.

When attaching to a PC, set terminal emulation type to VT100, specify the port used

by your PC (i.e., COM 1~4), and then set communications to 8 data bits, 1 stop bit,

no parity, and 19200 bps (for initial configuration). Also be sure to set flow control to

“none.” (Refer to “Configuring the Serial Port” on page 2-13 for a complete

description of configuration options.)

Note: If the default settings for the management agent’s serial port have been

modified and you are having difficulty making a console connection, you can

display or modify the current settings using a Web browser as described under

“Console Configuration” on page 3-5.

Switch Management

1-2

Remote Management via the Console Port

Configure the Switch Site

Connect the switch’s DB9 serial port to the modem’s serial port using standard

cabling. For most modems which use a 25-pin port, you will have to provide an

RS-232 cable with a 9-pin connector on one end and a 25-pin connector on the

other end. Set the modem at the switch’s site to force auto-answer mode. The

following is a sample initialization string: “ATQ1S0=1&D0&K0&W” as defined below:

Q1 : Inhibit result codes to DTE

S0=1 : Auto answer on first ring

D0 : Don’t care DTR

K0 : Disables DTE/DCE flow control

W : Write command to modem memory

Configure the Remote Site

At the remote site, connect the PC’s COM port (COM 1~4) to the modem’s serial

port. Set terminal emulation type to VT100, specify the port used by your PC (i.e.,

COM 1~4), and then set communications to 8 data bits, 1 stop bit, no parity, 19200

bps and no flow control.

In-Band Connections

Prior to accessing the Network Management Module via a network connection, you

must first configure it with a valid IP address, subnet mask, and default gateway

using an out-of-band connection or the BOOTP protocol.

After configuring the switch’s IP parameters, you can access the on-board

configuration program from anywhere within the attached network. The on-board

configuration program can be accessed using Telnet from any computer attached to

the network. The switch and stack can also be managed by any computer using a

Web browser (Internet Explorer 4.0, or Netscape Navigator 4.0 or above), or from a

network computer using network management software such as AccView.

Notes: 1. By default BOOTP is disabled. To enable BOOTP, see “IP Configuration” on

page 2-10.

2. Use the Network Configuration menu to specify the maximum number of

simultaneous Telnet sessions that are supported by the system (up to four).

3. The on-board program only provides access to basic configuration functions.

To access the full range of SNMP management functions, you must use

SNMP- based network management software, such as Accton’s free

AccView/Open software.
