1. About This Manual
This manual describes how to use the command line to configure Moxa’s layer 3 managed Ethernet
switches. Both the web interface configuration utility and command line interface help system
administrators easily and quickly manage, monitor, and configure Moxa’s managed Ethernet switch.

2. Understanding the Command Line
Interface
This chapter helps users understand the command line interface by giving a general overall introduction to
the command line operations.
Accessing the Switch
Users can connect to the switch using one of two methods: by console or by Telnet.
Logging in using the RS-232 Console
The Moxa managed switch features an RJ45 serial console port to allow users to connect to the switch and
configure settings.
NOTE
Moxa recommends using PComm Terminal Emulator for serial communication. This software is available
for free on the Moxa website. You can use other serial communication software, but the following
instructions may be different.
1. Use the RS-232 serial cable with RJ45 interface that is included with the switch.
2. Connect the RJ45 interface end to the console port on the switch, and the other end to the computer.
3. Download the PComm Terminal Emulator from the Moxa website and install the software.

connection. Configure the fields as follows: 115200 for Baud rate, 8for Data bits, None for Parity,
and 1for Stop bits.
7. On the Terminal tab, select VT100 as the Terminal Type, and click OK to continue.

8. Log in to the console using the default login name admin and password moxa. This password will be
required to access any of the consoles (web, serial, Telnet).
9. When successfully connected to the switch, you can start configuring the switch parameters by using
command line instructions.
NOTE
By default, the password assigned to the Moxa switch is moxa. We recommended changing the default
password after logging in for the first time to help keep your system secure.
Logging in using Telnet
Opening the Moxa switch’s Telnet or web console over a network requires that the PC host and Moxa switch
are on the same logical subnet. You may need to change your PC host’s IP address and subnet mask. By
default, the Moxa switch’s IP address is 192.168.127.253 and the subnet mask is 255.255.255.0. Your
PC’s IP address must be configured with an IP of the form 192.168.127.xxx and a subnet mask of
255.255.255.0.
NOTE
When connecting to the Moxa switch through Telnet or the web console, first connect one of the Moxa
switch’s Ethernet ports to your Ethernet LAN, or directly to your PC’s Ethernet port. You may use either a
straight-through or cross-over Ethernet cable.
NOTE
The Moxa switch’s default IP address is 192.168.127.253 with subnet mask of 255.255.255.0.

After making sure that the Moxa switch is connected to the same LAN and logical subnet as your PC, open
the Moxa switch’s Telnet console as follows:
1. In Windows, click Start > Run.
2. In the Windows Run window, enter telnet followed by the Moxa switch’s IP address (192.168.127.253).
You can also issue the Telnet command from a DOS prompt.

3. Log in to the Telnet console using the default login name admin and password moxa. This password
will be required to access any of the consoles (web, serial, Telnet).
4. When successfully connected to the switch, you can start configuring the switch parameters by using
command line instructions.
NOTE
By default, the password assigned to the Moxa switch is moxa. We recommended changing the default
password after logging in for the first time to help keep your system secure.
