Configuring the TCP Ports

By default, The TCP port numbers start at 7001 for serial port 1 and increase incrementally by one (+1) up to the number of serial ports that your console server supports. For example, a console server with eight serial ports has TCP ports 7001 through 7008. If these ports are already in use within your system, the default settings may duplicate and fail. If this occurs, change the default TCP base port for the serial port.

To change the default TCP base port number:

1. In a Units View window containing an ACS 5000 console server, click Appliance Settings - Ports - TCP Port in the side navigation bar.
2. Enter the new base port in the field.
3. Click Save.
4. Click Flash Required to save your changes to the console server Flash memory.

Console server TCP and UDP ports usage

The communication between the DSView 3 software plug-in and the console server is through a Secure Shell protocol (SSH). See the following table for port usage information.
