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.

Chapter 2: Using the System Configuration Program
Login Screen
Once a direct connection to the serial port or a Telnet connection is established, the
login screen for the on-board configuration program appears as shown below.
If this is your first time to log into the configuration program, then the default user
names are “admin” and “guest,” with no password. The administrator has Read/
Write access to all configuration parameters and statistics. While the guest has
Read Only access to the management program.
You should define a new administrator password, record it and put it in a safe place.
Select Console Login Configuration from the Management Setup Menu and enter a
new password for the administrator. Note that passwords can consist of up to 11
alphanumeric characters and are not case sensitive.
Notes: 1. Based on the default configuration, a user is allowed three attempts to enter
the correct password; on the third failed attempt the current connection is
terminated.
2. The ES3526G does not support stacking.
Please disregard any references to the stack when using the ES3526G.

Interface Type : Ethernet
IP Address : 10.1.113.29
Subnet Mask : 255.255.0.0
Gateway IP :
IP State : USER-CONFIG
<APPLY> <OK> <CANCEL>
Use <TAB> or arrow keys to move, other keys to make changes.
Parameter Description
Interface Type Indicates IP over Ethernet.
IP Address IP address of the stack you are managing. The system supports SNMP over UDP/
IP transport protocol. In this environment, all systems on the Internet, such as
network interconnection devices and any PC accessing the agent module (or
running AccView) must have an IP address.
Valid IP addresses consist of four numbers, of 0 to 255, and separated by periods.
Anything outside of this format will not be accepted by the configuration program.
Subnet Mask Subnet mask of the switch you have selected. This mask identifies the host
address bits used for routing to specific subnets.
Default Gateway Gateway used to pass trap messages from the system’s agent to the management
station. Note that the gateway must be defined if the management station is
located in a different IP segment. The default value is null.
IP State Specifies whether IP functionality is enabled via manual configuration, or set by
Boot Protocol (BOOTP). Options include:
USER-CONFIG - IP functionality is enabled based on the default or user specified
IP Configuration. (This is the default setting.)
BOOTP Get IP - IP is enabled but will not function until a BOOTP reply has been
received. BOOTP requests will be periodically broadcast by the switch in an effort
to learn its IP address. (BOOTP values can include the IP address, default
gateway, subnet mask, and TFTP server IP.)
