2.2. Obtain technical support information remotely

Technical support information (output results from show tech-support) can be obtained from the product by remote access via the Web GUI or TFTP.

2.2.1. Web GUI

In order to operate this product’s HTTP server, use the steps shown below to set up a network environment that allows remote access.

  1. Decide on the VLAN that will be used for maintenance.

  2. Set the IPv4 address on the maintenance VLAN. Set it using the ip address command.

  3. Permit access from the maintenance VLAN to the HTTP server. To specify a different VLAN than for management interface command settings, use the http-server interface command.

Execute the following operations by accessing the Web GUI.

  • Show technical support information on the Web GUI

    • In the “TECHINFO” menu, press the “Show in browser” button. The execution result of the “show tech-support” command is shown.

    • To close, press the web browser’s close button.

  • Obtain technical support information from the Web GUI

    • In the “TECHINFO” menu, press the “Obtain as text file” button to start the download automatically.

    • The file is saved with a file name in the following format.

      • techinfo_YYYYMMDDhhmmss.txt (where “YYYYMMDDhhmmss” is the date/time the command was executed)

2.2.2. TFTP

In order to operate this product’s TFTP server, use the steps shown below to set up a network environment that allows remote access.

  1. Decide on the VLAN that will be used for maintenance.

  2. Set the IPv4 address on the maintenance VLAN. Set it using the ip address command.

  3. Permit access from the maintenance VLAN to the TFTP server. To specify a different VLAN than for management interface command settings, use the tftp-server interface command.

If using a TFTP client, specify techinfo in the remote path for obtaining technical support information.

2.3. Save technical support information on external memory

You can use the copy tech-support sd command to save this product’s *technical support information (the output result of “show tech-support”) *on an SD card.
Before executing this command, you must insert an SD card.
The information is saved in the SD card with the following file name.

  • For SWX3220-30MC:

    • /swx3220-30mc/techsupport/YYYYMMDDHHMMSS_techsupport.txt

  • For SWX3220-30TCs

    • /swx3220-30tcs/techsupport/YYYYMMDDHHMMSS_techsupport.txt

  • YYYYMMDDHHMMSS ... Year, month, day, hour, minute, and second when the command was executed
