MRV Ports and Ports

An MRV is a terminal server that provides network access to serial console TTY ports.
It has two types of port: Asynchronous (serial) ports, and Ethernet (network) ports.

Asynchronous Ports:

There may be 8 (LX-4008), 16 (LX-4016), 32 (LX-4032), or 48 (LX-4048) Serial Ports, depending on model.
The DIAG port is for device configuration. The network port must be connected, and the IP address known.

Ethernet Ports:

There may be 8 (LX-4008), 16 (LX-4016), 32 (LX-4032), or 48 (LX-4048) Serial Ports, depending on model.
Serial Ports are assigned Telnet port numbers 2100-6800, and SSH port numbers 2122-6822, the DIAG Port is port #0.

Connecting:

Open a Telnet (or SSH) session to the MRV <IP address> and specify the ethernet port # associated with the serial port # you want to connect to.

From the PC, use Start, then Run, and enter cmd
At the DOS prompt, type: telnet <ip-address> port#

For Example:

> telnet 10.10.10.17 2100 - connect to MRV serial port #1

The IP-address is the fixed address of the MRV, followed by the serial ports 'socket port' number from the table above.

Port 2000 is the devices virtual management port.

Using Putty, click the telnet button, enter the MRV <IP address> for Host Name, and for the Port, enter 2100 to access MRV port 1, or 2200 to access MRV port 2, or 2300 to access MRV port 3, etc.
