The one bit of documentation that's missing from the Sophos XG inspector is the MAC address info for each network interface port. We would like this info to be included if at all possible.
Thanks for providing us with your feedback. We're looking into the feasibility of adding this information onto our Sophos XG Inspector and if so, we'll be planning to add this into one of our upcoming releases. We'll be sure to update you as we move this idea forward.
