3.5 MX100 Maintenance and Test Using
Communication Commands
The MX100 maintenance/test function is used by a network administrator to check the
communication status of the MX100.
Maintenance and test of the MX100 using communication commands can be carried out
by connecting the main module and a PC using an Ethernet cable, and using a terminal
emulator such as Telnet on the PC. The communication method is a command and
response type (a command is sent from the PC to the MX100 and a response is returned
from the MX100 to the PC). Only a single PC can connect to a single MX100.
Connecting the Main Module and the PC
See “Connection Procedure” in section 2.6.
Setting the Terminal Emulator
When carrying out maintenance and test of the MX100 using communication commands,
set the terminal emulator as indicated below. Specify the IP address of the MX100 and a
port number of 34317 for the destination of the terminal emulator.
