Strange Random Connections on LAN

Hi All, 

 

I'm having some strange random connections showing up on my LAN.  The only devices plugged into the Switch are 5 UAP access points and a few LocoM5s.   Has anyone experienced this?  

Rather than try to explain further here is a video of what I am seeing:  https://www.youtube.com/watch?v=O0vofEDVqY0

 

I am see these connection come in at about 150-250 connection per hour.  They don't appear to be doing anything.  Vendor lookup of MAC brings up nothing. 

 

Any ideas?

If you turn off the LocoM5s, does it stop happening?

First figure out where the MACs are coming from. It could be a mis-configured network branch, or it could be someone trying to intrude.

How are your APs protected, security wise? WPA2? Any open networks?

I'm not on-site, but I'll take a drive down to unplug the M5s to see if it stops. APs are protected with WPA2 and no open network.
