Configuration Options
For advanced management capability, the on-board 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 (such as SMC’s EliteView).
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 2-16 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 3-6.
In-Band Connections
Prior to accessing the switch’s on-board 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.
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 can also be managed by any computer using a Web
browser (Internet Explorer 4.0 or above, or Netscape Navigator 4.0

R EQUIRED C ONNECTIONS

or above), or from a network computer using network
management software such as EliteView
Notes: 1. By default BOOTP is disabled. To enable BOOTP, see
“IP Configuration”on page 2-12.
2. Up to four simultaneous Telnet sessions are supported
by this switch.
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 SMC’s
free EliteView software.

Log-in Screen
Once a direct connection to the serial port or a Telnet connection
is established, the log-in screen for the onboard 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 User Configuration from the Management
Setup Menu and enter a new password for the administrator. Note
that passwords can consist of up to 15 alphanumeric characters
and are not case sensitive.
Notes: 1. You are allowed three attempts to enter the correct
password; on the third failed attempt the current
connection is terminated.
2. If you have forgotten your password, you can return the
switch to its default settings by entering “ResetSystem”
(note, this is case-sensitive) as the user name (no
password required). The system will then reboot and
return to its default settings.
