If when you restart the Smoothwall hardware appliance, the small form-factor pluggable (SFP) on the network cards does not turn on, you might need to disconnect and reconnect the SFP from the server manually.
Older versions of the Smoothwall Filter and Firewall have an upper limit number of interfaces of 20. This included physical interfaces, and virtual interfaces. For example, VLANs and Bonds. If this limit was exceeded it caused problems upon booting.
We removed the limits on interface configurations in the Leeds-26 release. If you need more than 20 interface configurations, before starting advanced network configuration, we recommend that you upgrade your new installation to the latest version.
To free up some interface slots, you can remove legacy settings by using the command line to edit the files.
Procedure
- Use a program such as PuTTY, on port 222 to connect to the Smoothwall Filter and Firewall via SSH, and type the command: cd /settings/ethernet/nics
- To list the contents of this folder, type the command: ls.
You should see:
- Check the contents of all of these files.
- To remove any invalid or not in use, type the command: cat settings-X
Where X is the number of each file.
This shows you the configuration of each file:
- Make a note of the number of any empty ones, or any that contain invalid configuration.
- To remove the settings from the configuration, type the command: Vim /settings/ethernet/ifacemap.json
You will see a file that looks something like this:
The number references in which “settings” file this interface is contained. - To delete any lines mapped to a settings file, either not configured or configured incorrectly, move the cursor to the line in question and on your keyboard press d twice. Make sure that you do not delete the brackets {}.
- To exit the editor and commit the changes, press Escape, and then type :wq
- Log into the Smoothwall Filter and Firewall user interface and edit any network configuration interface setting, see our help topic, Adding new interface connections.
