I will be to implement a new Cisco solution based on Wireless Lan Controller + 6 LAP . But I don`t know if the Wireless Lan Controller can works with a 3COM, DELL or another switching solution distinct to Cisco Catalyst .
It can work with other vendors, you just have to know how to configure the trunk correctly, etc. The AP's most likely will be in local mode, so that is just an access port, its your WLC that needs to have a dot1q trunk. I'm guessing its the WLC2106?
