What is "DEV-17:xx:xx" coming from my Orbi Pro Satellite?

I was webbed into the router, and under Attached Devices, I saw there was this "DEV-17:xx:xx" coming from one of my SXS80's.  This specific SXS80 is listed twice, one as the SXS80, and one as the DEV-17:xx:xx address, they are coming from the same IP address (the same one as the SXS80), but the MAC Address is different.  I can't figure out what this is.
