Chapter 1: Switch Management

Configuration Options

For advanced management capability, the onboard management agent provides a

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

direct 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.

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

• Add ports to network VLANs

• Display system information or statistics

• Configure the switch to join a Spanning Tree

• Download system firmware

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 9600 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

“Configuring the Serial Port” on page 3-5.

Switch Management

In-Band Connections

Prior to accessing the switch’s onboard agent 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.

Note: By default BOOTP is disabled and the IP address is set to 192.168.10.1. See

“IP Configuration” on page 2-10.

After configuring the switch’s IP parameters, you can access the onboard

configuration program from anywhere within the attached network. The onboard

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

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

browser (Internet Explorer 4.0 or above, or Netscape Navigator 4.0 or above), or

from a network computer using network management software.

Notes: 1. This switch supports four concurrent Telnet sessions.

2. The onboard 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.
