What can be the problem if we connect the wlc on two different switch without vss ?
Are the distribution ports of the 5520 configured as LAG? If they are then it won't work.
Let me explain: The only way for the 5520 distribution ports be connected to two different (logical) chassis is when the ports are NOT LAG enabled. This means only one VLAN (per port) gets pushed.
The only way around this is to do the following:
1. Get a stack-capable switch: 2960S/2960X/2960XR, 3650, 3850 or 3560CX;
2. Connect the switches together to form a stack;
3. Connect the uplink of the stack to the distro/core switch;
4. Enable etherchannel on the stack to the controller; and
5. Connect the controller to the stack switches.

As your reply This means only one VLAN (per port) gets pushed.
But i know that we can mapped more dynamic interface for the same physical port so it can handle more vlan on the same port .

Yes i configure the port without lag this can produce some problem on the ap/client sso ?
do you test this ?
