No. No NLB. In my case it is a machinecntroller from Siemens (S7), which is sending a lot of multicasts and brings CPU to 85% in average.

If possible you can disable all edgeports and enable them one after the other and look which port is responsible for the high cpu load.

Marco_Lorenz · 10-06-2016

The reason for high cpu can be a device sending a lot of multicasts. Because multicasts are pricessed in the main cpu the load will inctease with the amount of multicasts being send to the device. You can figure it out by inspecting a tracefile. I ha...

What you need is a function called dhcp-relay or bootprelay. I think it has to be confugrwd on the same menu as you already configured the dhcp-server for the wireless topology. I habe no controller at hand to provide a detailled description, sorry f...
