Centralized Auth. / Local Switching - Common SSID

[jcartier]

Hi All,

I'm looking at a design where I would have a few remote sites and a centralized WLC.  My requirement would be to have a common SSID advertised across the remote sites and have that SSID locally switch; so to note tunnel all the traffic across the WAN back to the central site.

I know the feature I'm looking for is H-REAP with Centralized Authentication and Local switching...but I'm unsure of the second part...which is to have a common SSID across the remote sites.  How do I accomplish the second part?  I heard mention of using AP Groups in another post.  Just looking for more direction.

You're all correct except on the last part.

what you want to do is configure your SSID in advanced options to enable HREAP Local switching.

Then only the APS at remote site you move to HREAP mode one by one.

From there, all the APs you configured as HREAP will be locally switching traffic and the APs in local mode will still forward traffic through the controller.

I hope this clarifies ?

Alright...

So if I configure the WLAN to support H-REAP Local Switching...is their anything further I need to do on the AP side?

For instance...if the WLAN in question is called "Internal"...and I want this SSID to be common at the remote sites...will I then need to map it to a local Vlan?  And will that vlan need to be consistance across the board? What is remote site 1 uses vlan 100...and remote site 2 uses vlan 200?

Your "local" mode APs (so central site) will use the interface of the WLC mapped in the WLAN.

The HREAP APs, you can go on each one of them (wlc web page "wireless->aps"), in the hreap tab and define the vlan on which the AP will drop the ssid traffic. So that vlan is dependent on the switch where the hreap ap is connected and can be different for each hreap AP.

Hi,

I second Nico.. here is the best config example for HREAP..
