Hi,

First understand the two modes:

When you have WLCs on both location:

In local mode, an AP creates two CAPWAP tunnels to the WLC. One is for management, the other is data traffic. This behavior is known as "centrally switched" because the data traffic is switched(bridged) from the ap to the controller where it is then routed by some routing device.

When you have WLC only on Mian site:
Flex Connect also known as HREAP by the old timers, allows data traffic to be switched locally and not go back to the controller. It basically causes the AP to behave like an autonomous AP, but be managed by the WLC. In this mode, the AP can still function even if it looses connection with the controller. Also, anytime you want to switch traffic locally, that would be the time to use Flex Connect. I used it once when my users were needing the wireless and wired networks to be on the same subnet for broadcasting reasons.

Thanks for the reply
Let's say I have wlc in site A and Site B

And I have ssid Test at site A and site B also

What will happen in this case , User feels that is connecting to another SSID

I have the same scenrio:

Site A and Site have individual WLCs with same ssid name: Test, with same security types...

User will not feel anything...it will connect smoothly without any issue.
