Hi everybody,


I'm trying to configure Cisco 4402 series wireless lan controller on a proof of concept lab, but it's generating extremely high LAN utilization (around 600-700 Mbps) on its connected port to backbone switch. We are using GLC-T on 4402's port 0 for local connectivity. This traffic is starting even we do not use any access points in wireless network.


I configured controller 2 times after resetting to factory default, but the result is the same.


Best Regards

Ozan,

     What is the config on the connected switchports?  In genearl you want to prune the non-used VLAN from the trunk.

problem has been solved by adding "switchport trunk allowed vlan x,y,z" command to the backbone switch.

Ozan,


So why the high utilization then? I understand you didnt have the vlans added to the switch .. but what caused the massive traffic load?
