DES-3550 Layer 2 Fast Ethernet Switch
1
INTRODUCTION
The Switch can be managed through the Switch’s serial port, Telnet, or the Web-based management agent. The Command
Line Interface (CLI) can be used to configure and manage the Switch via the serial port or Telnet interfaces.
This manual provides a reference for all of the commands contained in the CLI. Configuration and management of the Switch
via the Web-based management agent is discussed in the Manual.
Accessing the Switch via the Serial Port
The default settings of the Switch’s serial port are as follows:
• 9600 baud
• no parity
• 8 data bits
• 1 stop bit
A computer running a terminal emulation program capable of emulating a VT-100 terminal and a serial port configured as
above is then connected to the Switch’s serial port via an RS-232 DB-9 cable.
With the serial port properly connected to a management computer, the following screen should be visible. If this screen does
not appear, try pressing Ctrl+r to refresh the console screen.
Figure 1-1. Initial CLI screen
There is no initial username or password. Just press the Enter key twice to display the CLI input cursor − DES-3550:4#. This
is the command line where all commands are input.
