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. So you don’t have to use this Powershell script, but you could if you want to.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. Search vendor, manufacturer or organization of a device by MAC/OUI. It takes a while for the loop to run, but you will get a nice output of all the MAC addresses and their corresponding vendors.Īfter writing this script, and thinking it was so useful, I found this link to a MAC address lookup that lets you do multiple searches. Fast and easy MAC address lookup on IEEE directory and Wireshark manufacturer database.
It doesn't connect to any sort of backend API or database. $macvendor = (($webrequest.Content -split ’\,’) -split ’"’)īut we can do better than that. The OUI lookup tool downloads a JSON-ified version of the manuf file and does its work in your browser. $webrequest = Invoke-WebRequest -Uri “$mymac/csv” We can do the same thing with this following Powershell script: Then you go to and paste in your MAC address, and you’ll see that from the burned-in address, the hardware you’re using is an Apple device. Here’s an example: You find that the MAC address of your computer is C8-BC-C8-12-34-56. So when you’re administering network equipment, sometimes you do a MAC address lookup to see what kind of devices are attached to a switch. Yay! Ok, next, the switch has some tool called a MAC address table which keeps a table of IP addresses and their corresponding MAC addresses.

So now the PC has an IP address and a MAC address. In a little more detail, PC’s have a MAC address, and usually the router provides an IP address for the PC. From what I learned in my CCNA bootcamp class, your PC gets connected to the internet through something like this: PC -> switch -> router -> ISP -> Magical Awesome internet. Ok so the point of all the background information is that stuff that gets connected to the internet has to have a MAC address. Manufacturer’s registered identification number and may be referred to If assigned by the manufacturer, a MAC address usually encodes the And MAC addresses are most often assigned by the manufacturer of a network interface controller (NIC) and are stored in its hardware.
According to Wikipedia, a MAC address is a unique identifier assigned to network interfaces for communications on the physical network segment.
