Are you referring to AP/WLC management traffic or user traffic?


If you want to separate user traffic you just set up dynamic interfaces, and not to route between them on your L3 device, whether you do it via ACL or VRF.


If you want to separate the AP management as well, you can put companies A, B, and C's AP's in three different management subnets, but they all have to come back and talk to the WLC.

Hi,

If you mean that Company A's SSID will not be broadcasted into B & C "floor" and vice versa, then YES. It's called AP Groups.


You can "group" each AP into a "folder" (excuse my term) and from each so-called folder, you can specify what SSID's to enable/broadcast and what SSID not to use.


Is this what you are looking for?

thank you all for your reply


I would like to ask you another question fo another scenario.


I have one WLC installed in one subnet, let's say in the head quarter network, while the LAPs are installed in the branches and there is WAN connectivity between the HQ and the branch and OSPF routing is enabled between this WAN network. How can I do my configuration in order to register the LAPs installed in the branch with WLC installed in the HQ?


Thanks,

Specific to AP Groups, here is a video i did that will explain in detail how it works (AP GROUP LAB):

If you are going to do remote access points one thing you may want to consider H-REAP.

If you can ping the controller from the subnet where the remote APs will reside, then you have all the layer 3 connectivity you need. (Unless you have ACLs blocking the LWAPP ports on the Management or AP Manager interfaces, of course.)

Hi Jaber,

As what George's post recommends, use H-REAP. You can also "mix" H-REAP with AP Groups too.
