This utility requires curl, wget or libwww-perl to be installed. Update-oui fetches the current version of the OUI and IAB lists from Update-oui - download new version of the OUI and IAB lists Also, I've been looking for some info on the meaning of designated root vs designated bridge and any clarification on that subject would also be appreciated.I have found some tools that seems to update the OUI MAC address vendor database on my system, like get-oui, airodump-ng-oui-update or update-oui : update-oui(8) OUI update-oui(8) If someone can help me understand more about the designated root, that would be helpful. My issue here is that we have been having ongoing intermittent network issues that I suspect is caused by broadcast storms and right now, I am focused on trying to accurately understand how the network is working as a first step. When I go to the designated root for all nodes shows as 8000.325e13xxxxxx - I have tried to identify the device on my network using arp tables and also using a MAC lookup to identify the manufacturer but I have been unable to find anything resembling even a distant match. It would seem that one way or another, based on the network matrix, all other units are adequately able to make wireless connections either directly to this node or to another, tertiary node.ģ. This Connect, (KITCHEN) is identified as a secondary node in the network matrix. There is only one Sonos device (Connect) with a wired connection into a TP Link Switch which in turn is plugged into an Arris wifi phone/cable modem gateway.

All Sonos units are identified as either secondary or tertiary units which to me is fine but would indicate that another, non-Sonos device is acting as root. Just continuing to try to do some diagnostics on a buddy's Sonos setup and having difficulty identifying the designated root based on its mac address.
