Chapter 1: Managing the Switch
Configuration Options
The CheetahSwitch Workgroup-4508 provides a menu-driven system
configuration program that can be accessed through a direct console connection
or modem connection to the serial port on the switch’s rear panel (out-of-band),
or by a Telnet connection over the network (in-band).
The switch 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 switch’s management agent is based on SNMP (Simple Network
Management Protocol). This SNMP agent allows the switch to be managed from
any PC on the network using in-band management software, such as Accton’s
AccView/Open.
Once you have connected a terminal or PC to the serial port on the switch, you
can perform the following tasks:
• Enable/disable any port
• Set the communication mode for any port
• Configure SNMP parameters
• Configure the switch to join a Spanning Tree
• Add ports to VLAN groups
• Mirror data from a target port to an analysis port
• Display system information or statistics
• Download system firmware
• Restart the system

CheetahSwitch Workgroup-4508
Making Connections for System Configuration
The switch includes a menu-driven configuration program. The ASCII interface to
this program can be accessed by making a direct connection to the serial
port on the rear panel, or by a Telnet connection to the switch over the network.
This section describes how to access the menu-driven configuration program via:
• Onsite connection
A terminal or workstation connected to the serial port on the rear panel
• Modem connection
A workstation connected to the serial port of a remote switch via modems
• Telnet connection
A workstation connected to a remote switch via a Telnet connection
It also describes how to access the embedded Web agent over the network using
any standard browser, or with AccView network management software or other thirdparty management software.
Onsite Connection
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 the back 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
both handshaking and flow control to “none.”
Modem Connection
Configure the Switch Site: Connect the switch’s DB-9 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. You do not have to set the
modem at the switch’s site, because the switch will automatically configure it to
auto-answer mode.
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.

Management Guide
Telnet Connection
Prior to accessing the switch via an in-band Telnet connection, you must first
configure it with a valid IP address, subnet mask, and default gateway using an
out-of-band connection or BOOTP protocol. After configuring the switch’s IP
parameters, you can access the on-board configuration program from anywhere
within the attached network.
Note: Up to four Telnet sessions are supported.
In-Band Network Connection
The on-board configuration program can be accessed using Telnet or a Web
browser (Internet Explorer 4.0 or above, or Netscape Navigator 4.0 or above)
from any computer attached to the network. It can also be managed from a
network computer using management software such as AccView.
Notes: 1. Prior to accessing the switch via a direct network connection, first
configure it with a valid IP address, subnet mask, and default gateway
using an out-of-band connection or BOOTP protocol.
2. 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. Accton provides a
Windows-based SNMP software package called AccView/Open. If you
require this software, please contact your Accton distributor. Also note
that AccView’s CheetahSwitch Manager module can be easily integrated
into most third-party management platforms.

Management Guide
Assigning SNMP Parameters
Use the SNMP Configuration screen to display and modify parameters for the
Simple Network Management Protocol (SNMP). The switch includes an on-board
SNMP agent which monitors the status of its hardware, as well as the traffic
passing through its ports. A computer attached to the network, called a Network
Management Station (NMS), can be used to access this information. Access
rights to the on-board agent are controlled by community strings. To
communicate with the switch, the NMS must first submit a valid community string
for authentication. The options for configuring community strings and related trap
functions are described in the following figures and table:

Downloading System Software
Using TFTP Protocol to Download Over the Network
Use the TFTP Download menu to load software updates into the switch. The
download file should be an ES4508 binary file from Accton; otherwise the agent
will not accept it. The success of the download operation depends on the
accessibility of the TFTP server and the quality of the network connection. After
downloading the new software, the agent will automatically restart itself.
Parameters shown on this screen are indicated in the following figure and table.

Management Guide
Configuring the Switch
The Device Control menu is used to set the communication parameters for
individual ports, and to fine-tune the performance of your switch by adjusting the
forwarding mode, flow control, and specific Spanning Tree parameters.
Configuration menus are also provided for advanced functions, such as Virtual
LANs, and port mirroring. Each of the setup screens provided by the
configuration menus is described in the following sections.

Control Duplex
Parameter Default Description
Type Shows port type as 1000BASE-SX.
Admin ENABLED Allows you to disable a port due to abnormal behavior (e.g.,
excessive collisions), and then re-enable it after the problem
has been resolved. You may also disable a port for security
reasons.
Flow Control ON Used to enable or disable flow control. Flow control can
eliminate frame loss by “blocking” traffic from end stations or
segments connected directly to the switch when its buffers fill.
Back pressure is used for half duplex and IEEE 802.3x for full
duplex. Note that flow control should not be used if a port is
connected to a hub.
Speed and Duplex 1000-FULL Indicates the current port speed and duplex mode (1000-FULL
or AUTO). Although ports on the switch can be set for autonegotiation, operation is restricted to 1000 Mbps, full duplex.

Using the Spanning Tree Algorithm
The Spanning Tree Algorithm can be used to detect and disable network loops,
and to provide backup links between switches, bridges or routers. This allows the
switch to interact with other bridging devices (that is, STA-compliant switch,
bridge or router) in your network to ensure that only one route exists between
any two stations on the network. For a more detailed description of how to use
this algorithm, refer to “Spanning Tree Algorithm” in Chapter 4.
