I have around 800+ access points, and 2 identify controllers. I have all ap's and 2 controllers in same vlan.Will there be any issue.

If i want to create 4 subnets for 800+ access points and seperate the ap and controller subnet, how can i achieve it, do i need toplogies?

We also have 4000 end users in a single subnet, i know its a lot, but i want to split them into 12 subnets, how can i achieve this, what kind of topolgies i need to have.

I want to bridge traffic locally at AP itself and use only one port say esa1 which will be the management port ......

Hi, so let's answer your questions...

1)I have around 800+ access points, and 2 identify controllers. I have all ap's and 2 controllers in same vlan.Will there be any issue.
A: Yes, a lot of broadcasts.

2) If i want to create 4 subnets for 800+ access points and seperate the ap and controller subnet, how can i achieve it, do i need toplogies?
A: In reference to 1) I hope that the subnets are also in a different VLAN.
Create 4xAP VLANs in the switch network and 1x VLAN for the controller and the L3 core switch should route between the subnets.
Yes, you always need a topology.

3) We also have 4000 end users in a single subnet, i know its a lot, but i want to split them into 12 subnets, how can i achieve this, what kind of topolgies i need to have.
A: as per 4) you want bridge@AP - you'd do that with i.e. NAC or RADIUS.
Just put the users in a different role (VLAN) that the NAC/RADIUS provide to the controller.

4)I want to bridge traffic locally at AP itself and use only one port say esa1 which will be the management port ......
A: no problem to do that

But why not get some local/remote help from a Extreme Partner for 1-2 days as 800APs is not what I call a small network.....
