Two WLC 3504 (HA) in main DC and ap in remote locations

Hello for everybody.

 

There is a network of 5 remote sites and a central data center. We plan to implement the following wifi scheme - there are two wlc 3504 (high availability - one active and one standby ) in the central dc, to which all ap 2800 series
from remote sites are connected and registered. All dhcp pools are created on routers on remote sites (pools for ap management and pools for users).

 

Is it possible to realise with the specified hardware models? And is it possible to remotely register a point on the controller
using flexconnect?

Yes, FlexConnect AP is the way to go.

Here is more details that you can refer

Rasika thanks for answer.

I read this guide some earlier.

But we at the moment we are considering the following scheme - each site has one wifi net to connect users by password, one with SMS authorization and most likely, one or two wifi networks for office needs. If i understood correctly, for this scheme we need only apply flexconnect in wlc and create groups for it.

And maybe someone can recommend guide or best practice book for adjustment switch and router for remote location and central DC.

For example, how the ports on the switch at the remote location should be configured, how the ports on the core-switch  should be configured (where the controllers is connected). I found different info - some people recommend use trunk for remote switch, some - access with vlan for management of ap. And same situation about wifi controllers into central DC - some recommend use trunk port, but some - access with vlan for ip managemet of wlc.

 

General scheme in attache. 

If describe it briefly, remote routers is connected to the main dc router gre/ipip tunnel. All dhcp pools are created on routers on the sites, in the same place routing is configured. Two wlc 3504 (HA/SSO) is located in the main dc. Suppose to create a subnet for wlc management and assign ip addresses manually. Then create interfaces corresponding to wifi networks on remote sites on wlc.

"I found different info - some people recommend use trunk for remote switch, some - access with vlan for management of ap. And same situation about wifi controllers into central DC - some recommend use trunk port, but some - access with vlan for ip managemet of wlc".

 

WLC connected switchport should be configured as trunk ports, if you connect multiple ports (ex 2 ports of each 3504 connects to same switch) in each controller, enable LAG as well.

If you use FlexConnect mode AP (with local switching), then you do not want to have seperate dynamic interface for each site. As wireless user traffic will be terminated locally at branch.

 

FlexConnect AP connect switchports also need to be configured as Trunk ports. AP IP should be on same vlan as native vlan of that trunk port. Assumption is WLAN traffic is locally switched at each branch.
