See set server on page 173 in Appendix B The CLI commands.

Setting up the line on your Console Server

The default use of the Console Server is as a Console server. Therefore all lines are set with a service of “Reverse Telnet”. This allows a user on the LAN to be able to telnet into the ports and access the attached devices.

Each port also requires a TCP socket number in order to work. By default, the unit is set to use numbers 10001 to 10024. You can change these to any other socket number as long as there is no conflict on the network.

For an explanation of other line services see Appendix E Summary of Line Service Types.
