when I try to enable a WLAN that is using the same SSID as another WLAN I get this message
The following errors occurred while updating the WLAN:
WLAN with duplicate SSID and L2 security policy found.
each location has its own interface because each site is setup on our 6509 with a different VLAN. What is the best way to work around this.

That a look at what George posted. You have to understand that you only need to create the one SSID. Te interface you specify in the WLAN gets override by what interface you define in your AP Group.
To make its easy:
SSID: secure
AP Group: Site 1
SSID: secure
Interface: vlan x
AP Group: Site 2
SSID: secure
Interface: vlan y
AP Group: Site 3
SSID: secure
Interface: vlan z

What you are trying to do will not work as you can see. The best way is to define your dynamic interfaces if traffic will come back to the WLC and create ap groups. This will allow you to specify APs to have a particular SSID and you define what interface you want the traffic to egress. If you plan on putting traffic local to the site of the access points, then you will need to look into FlexConnect.

We will be using HREAP, but all traffic comes back the main site, so there is no reason for the sites to have local switching. I have AP groups setup for each site and each interface is a dynamic interface.

Hummmm... Why are you using HREAP if you are brining back all the traffic ?

Because we only have a T1 between the sites and being health care provider we have to make sure the traffic is secure in between the sites.

So break down HREAP. Just do AP grooups like Scott mentioned .

That goes back too, I have 2 WLAN's, different interfaces because of the VLAN's are different but same SSID. I can't have the SSID enabled on both WLAN's? So how will having AP goups help me if I can't enable the SSID?

Maybe I am missing something ...
You have the same SSIDs but you are mapping them to different VLANs
Its a video I posted on my blog about ap groups ..
HREAP is used to dump traffic local. You arent looking to do that. You want to bring the traffic back and still have subnets

Hi Scott,
I have this request where I have to advertise the same SSID on both local-mode APs and FlexConnect APs.
For this reason I have to create two SSIDs, same name, same authentication (802.1x). Any tips for this scenario?

Hi Florin,
How did you implemented this?
