Hi,

I have the following devices:

OC200 v1.0

ER605 v2.0

SG3210X-M2 v1.0

EAP690E HD v1.0

They are all using the latest firmware. EAP690E HD is using the power adapter that come with it.

EAP690E HD is connecting to SG3210X-M2 on Port #2.

Recently, I noticed there are devices having MAC address similar to 00-CF-D5-D2-E8-65 connected to Port #2. It doesn't have any IP adddress assigned and no traffic according to Clients page. And after I block, a different MAC address will connect again, and they all started with 00-CF-D5-XX-XX-XX.

Any idea what is this MAC address?

Since Port #2 is connected to EAP690E HD already. How can this MAC address connect to the same port? I think it may have to do witht the settings, but just couldn't found where. Please help?
