Hi,

I'm having problems with switches and their ports being blocked. Running Omada system with OC200 connected to SG2428p and a SG2210P connected to the main switch. Over night the 2210 was blocked multiple times, it has CCTV cameras, access control screen, Sky Booster and EAP 235 plugged in with no problem from these devices. Please see screen shot, there are more alertbut this gives an idea of the problem  Ant thoughts would be helpful.
