Hello,

I have encounter a problem. I have ER605. From the port 2 I have connected TL-SG2008 switch to port 1 and from port 5 of switch there is connected EAP610. To ports 2, 3 and 4 of the switch there are lan cables connected, but no devices at the moment. Now I am constantly getting error "Switch's port Gi1/0/3 was blocked". Can there be anything related to configuration? Or something with the wiring?

From the previous posts with related questions, I got an idea that it might be happening due to loopback, but as I have mentioned, no devices are connected to port 3. Only cable. Can it be that there is a problem with the wire itself? Maybe short-circuit might cause it? I will be at the site next week, so I would like to have some insights about this issue.

Best Regards,

Giedrius
