CLI
The Switch 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 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
•
115200 baud
•
8 data bits
•
No parity
•
One stop bit
No flow control
Users can also access the same functions over a Telnet interface. Once an IP address has been set for the Switch, users
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:
