![]() Once you know the manufacture, you can look up documentation if needed. Manufacturer information can often be difficult to find in any other way so the OID comes in quite handy in that regard. #Wireshark oui lokoup macOID data can also be used to determine the vendor that manufactured the device, just as MAC addresses on networking hardware can usually be traced to specific vendors. Another OID might tell you about uptime, while a third OID reveals details about fan speed. For example, you can grab an OID that tells you about the temperature of a device. The OID is based in part on the Management Information Base, or MIB, to which the device belongs.Įach OID contains information about a particular aspect of a device, which can be helpful when troubleshooting a network or studying the network topography. What’s an OID?Īn OID is a unique identifier assigned by the SNMP protocol to the various components of individual devices. ![]() 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.Is there a device on your network that you want to learn more about or monitor? Being able to look up the device’s Object Identifiers, or OIDs, is the key to gleaning the information you’re after. 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. ![]()
