How to Extract a 3Com Switch Configuration

3Com Switch configuration retrieval instructions

(Tested on a 3Com Switch 5500-SI)

Using SSH, Telnet or the Console.

For this procedure you will be using the Command Line Interface (CLI) of your 3Com Switch device using an SSH client (such as OpenSSH or Putty), Telnet or through the console port. We would recommend using either SSH (for remote connections) or using a direct connection to the console port. Telnet provides no encryption of the communications and therefore your authentication credentials and configuration would be vulnerable if a malicious user were to monitor your connection. 

1.       Connect to the 3Com Switch using your favourite SSH client, Telnet or a direct console connection.  (NB: You may need to set the baud rate to the appropriate speed for your device.  A list of standard rates can be found at the end of this document.  On our 3Com test device, the baud rate was 19200)

2.       Press ENTER twice to get started.

3.       If required, log in using your administration authentication credentials.

4.       Execute the following CLI command and capture the output (possibly using the cut and paste facility):

display current-config

1.       Save the captured output to a file and, if necessary, remove any visible page lines (i.e. --More--).

2.       The resulting file should now be auto-detected as a 3Com device when entered into Nipper Studio. 

If you are unsure about the baud rate that your device is set to we would suggest trying the most common default baud rates which are 9600, 19200 & 115200

For your convenience, we have listed the other baud rates commonly supported by serial ports below:

110

300

600

1200

2400

4800

14400

28800

38400

56000

57600

 Standard baud rates supported by some serial ports:

128000

153600 

230400

256000
