can i have ap's and controller in same vlan


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.....

For (3), IdentiFi(TM) 9.21 now directly supports VLAN/Topology pooling. You can create the 12 individual topologies, group them in a single Topology Group (new) and then select what allocation algorithm you want to use (MAC based filter [last few bits of the Mac address], Random, Round-Robin, Least Used). Configure the Topology group as the default topology for the service/role.

You can create Topology Groups for any topology (Bridged@AP, or Bridged@controller). However, each group can only have topologies of one type... all B@AO or all B@C - type mixing is not supported.

As per user guide (and my GUI) only routed or bridge@EWC is an option to select for the topology group.

Hi paulo thanks for your reply.

configuring 12 individual topologies with B@AP and grouping them into a group works right as i want to switch traffic at AP itself....

Just i need to map the wlan services to the group am i right ?

Hi Ronald

fOR YOUR ANSWERS 2&3 : Can I create 1 physical topology for management and 4 b@AP toplogies for 4 subnets of ap's ?

will the single physical interface register all the 4 subnets (different vlan) AP's.

and for point 4: Can I create 12 topolgies (b@ap) , and map 12 different wlan services to 12 topogies ? will that work ?

and for your other answer: "routed or bridge@EWC is an option to select for the topology group", does'nt suit my requirement right? as i need to bridge traffic at ap.
