TCP Port Numbers for Serial Ports
The TCP port numbers by default start at 7001 for serial port 1 and increments up to the number of serial ports that your ACS unit has. For example, an ACS with 8 serial ports have TCP ports 7001 through 7008. The ACS administrator may change the default port numbers, so if you use the defaults and they fail, check with the administrator to find which port numbers to use.
To Use Telnet to Connect to a Device Through a Serial Port
For this procedure, you need the hostname of the ACS or its IP address and the TCP port number for the serial port to which the device is connected.
telnet hostname | IP_address TCP_port_number
To Close a Telnet Session
Enter the Telnet hotkey defined for the client. The default is “Ctrl ]” and “q” to quit.
To Use SSH to Connect to a Device Through a Serial Port
For this procedure, you need the username configured to access the serial port, the TCP port number, and the hostname of the ACS or its IP address.
To use ssh in a shell, enter the following command:
ssh -l username : TCP_port_number ACS_IP_address
To Close an SSH Session
Enter the hotkey defined for the SSH client followed by a dot “.”. The default is “~.”
Note: Make sure you enter the escape character followed by a “.” at the beginning of a line to close the SSH session.
