USING THE CONSOLE CLI
The DES-3550 supports a console management interface that allows the user to connect to the switch’s management agent via a
serial port and a terminal or a computer running a terminal emulation program. The console can also be used over the network
using the TCP/IP Telnet protocol. The console program can be used to configure the Switch to use an SNMP-based network
management software over the network.
This chapter describes how to use the console interface to access the switch, change its settings, and monitor its operation.
Note
: Switch configuration settings are saved to non-volatile RAM using
the save command. The current configuration will then be retained in the
switch’s NV-RAM, and reloaded when the Switch is rebooted. If the Switch
is rebooted without using the save command, the last configuration saved
to NV-RAM will be loaded.
Connecting to the Switch
The console interface is used by connecting the Switch to a VT100-compatible terminal or a computer running an ordinary
terminal emulator program (e.g., the HyperTerminal program included with the Windows operating system) using an RS-232C
serial cable. Your terminal parameters will need to be set to:
• VT-100 compatible
• 9600 baud
• 8 data bits
• No parity
• One stop bit
• No flow control
You can also access the same functions over a Telnet interface. Once you have set an IP address for your Switch, you can use a
Telnet program (in VT-100 compatible terminal mode) to access and control the Switch. All of the screens are identical,
whether accessed from the console port or from a Telnet interface.
After the Switch reboots and you have logged in, the console looks like this:
