Telnet to Serial Port Feature

This section describes how to set up and use the Telnet to a Serial Port feature

of the SCS. It assumes that you have otherwise configured the unit, and that the

console server has connectivity to the network.

The system administrator can assign the serial ports individual IP port numbers

and/or distinct IP addresses. You can disable authentication on the console

server for directly connected serial ports. This section discusses the setup, use,

and security considerations for port access.

Accessing Serial Ports

You can set up the Telnet to a Serial Port feature so that you can access a serial

port by entering a predefined IP port number on the Telnet client’s command line

or by using distinct IP addresses assigned to each serial port. You can set up the

console server in several simple steps.

The reason to use one access method or the other is site specific:

 If your site has limited IP addresses available, then you may want to

define separate IP port numbers for the serial ports and use these

numbers in combination with the console server’s IP address.

 If you have enough IP addresses available and would like to assign

names to each IP address (using your DNS server), then you may want

to define an IP address per serial port.

IP Port Numbers

If you assign an IP port number to a serial port, enter the full command on the

client machine to directly access the serial port:

$ Telnet console_server_ip_addr ip_port_number

or, if the name of the console server can be resolved to an IP address (DNS):

$ Telnet console_server_name ip_port_number

You must predetermine and establish the cross-reference of the console server

serial port number and the specific console server IP port number on the console

server. To access the proper port, users must be aware of this cross-reference.

If you are using multiple console servers, the IP port number assignments can be

the same on each console server. An example of this cross-reference is:

1 2 ... 100 101 102 103 104 105 106 107 108 109 110 ... 140 141
