Console Configuration
1. Connect to the switch console:
2. Connect the DB9 straight cable to the RS-232 serial port of the
device and the RS-232 serial port of the terminal or computer
running the terminal emulation application. Direct access to the
administration console is achieved by directly connecting a
terminal or a PC equipped with a terminal-emulation program
(such as HyperTerminal) to the switch console port.
3. Configuration settings of the terminal-emulation program:
4. Baud rate: 115,200bps, Data bits: 8, Parity: none, Stop bit: 1, Flow
control: none.
5. Press the “Enter” key. The Command Line Interface (CLI) screen
should appear as below:
6. Logon to Exec Mode (View Mode):
7. At the “switch_a login:” prompt just type in “root” and press
<Enter> to logon to Exec Mode (or View Mode). And the
“switch_a>” prompt will show on the screen.
8. Logon to Privileged Exec Mode (Enable Mode):
9. At the “switch_a>” prompt just type in “enable” and press
<Enter> to logon to Privileged Exec Mode (or Enable Mode). And
the “switch_a#” prompt will show on the screen.

Terminal Mode). And the “switch_a(config)#” prompt will show
on the screen.
12. Set new IP address and subnet mask for Switch:
13. At the “switch_a(config)#” prompt just type in “interface
vlan1.1” and press <Enter> to logon to vlan 1 (vlan1.1 means
vlan 1). And the “switch_a(config-if)#” prompt will show on the
screen.
14. Command Syntax: “ip address A.B.C.D/M”. “A.B.C.D” specifies
IP address. “M” specifies IP subnet mask. “M”= 8: 255.0.0.0,
16:255.255.0.0, or 24: 255.255.255.0.
15. For example, At the “switch_a(config-if)#” prompt just type in
“ip address 192.168.1.10/24” and press <Enter> to set new IP
address (192.168.1.10) and new IP subnet mask (255.255.255.0)
for Switch
