5. CLI Management
Locate the included RS-232 null-modem cable. Refer to Section 1.3for the null-modem cable’s configuration.
Attach the DB9 female connector to the male DB9 serial port connector on the switch.
Attach the other end of the DB9 cable to an ASCII terminal emulator. Or, connect the cable to a PC COM1 or
COM2 port on a PC running a utility such as Microsoft Windows HyperTerminal.
At the COM Port Properties Menu, configure the parameters as follows:
Baud rate 57600
Stop bits 1
Data bits 8
Parity N
Flow control None
5.1 Login
The command-line interface (CLI) is a text-based interface. Access the CLI through either a direct serial
connection to the device or a Telnet session. The switch’s default values are listed below.
Username:
admin
Password:
admin
After you login successfully, the prompt appears as “#” if you are the first login person and your authorization is
administrator; otherwise, it appears as “$.” The former means you act as an administrator and have all system
access rights. The latter means you act as a guest and are only allowed to view the system without permission to
apply configuration settings to the switch.
5.2 Commands
To see the CLI mode commands, type in a “?” after the prompt, then all commands will be listed. All command
scan be divided into two categories, global and local commands. Global commands (end, exit, help, history,
logout, restore default, restore user, save start, and save user) can be used in either administrator or user mode.
For details, refer to
Section 5.2.1
.
Command instructions residing in user mode are local commands. A local command can have the same name
as a remote command, but it performs a totally different function. For example, show in IP mode displays the
IP information; however, it displays the system information in system mode. For more details, refer to
Section
5.2.2
.
Once you log into the switch as described in
Section 5.1
, the screen shown in Figure 5-1 appears.
