Perhaps there is a better place to ask this, but having just begun using Aruba access points, I've noticed that we see a lot of traffic with some very strange MAC addresses, all in the 00:00:5e OUI range that is reserved by IANA for various special uses. In particular we see a lot of 00:00:5e:00:02:50, which is reserved for VRRP, and 00:00:5e:00:03:50, which is completely unassigned.
Since these don't seem legitimate I wonder if we have someone trying to conceal their identity, or some sort of software misconfiguration. Searches here and there on the net don't really give me any hints, so I wondered if anyone has see such addresses? Aside from VRRP use, is there any legitimate reason why such MAC addresses would appear? I wondered if there is just some standard way that the wireless world uses them, and, having spent most of my time in the wired world, I'm just not familiar with it?
Thanks!
