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:
