I have and will have more multiple sites that are separate offices and will be using HREAP to each location. Each site like I said will be separate but will have the same SSID. I am assuming I will need separate AP groups, virtural interfaces and WLANS for each site?
Solved! Go to Solution.
If your doing central switching, then your wlan ssid will be tunneled back to the wlc and be placed on vlan 111. The AP's should be on a different vlan, so you have the ap's in each site on vlan 110, that should be fine. This can be an access port vlan 110, since you are not doing any local switching.
First off, if the wlc is centralized and will be supporting all the remote sites, there is only one VIP address configuration on the wlc. The same with the wlan's. The wlan's is the SSID... You would want to have the same WLAN SSID at each site so users from one site can go to another site without having to add a new wireless profile.
AP Groups might not be required. If you plan on having the same SSIDs at each site, you really dont need to use ap groups. When an ap is in h-reap or FlexConnect mode, you define in the ap the vlan mapping. What SSID is mapped to what vlan at that site. If you want to only have certain SSIDs broadcasting at a site, then you use ap groups.

here is an example, I have a site that I am assigning vlan 111 to the wireless, I assign the interface to that vlan, then also assign the AP's under the H-REAP tab to the same vlan. With out AP groups how do I get the SSID to broadcast on those AP's? then I have a site I will be assigning vlan 112 too, This site will also have the same SSID but different network.
If I am understanding this right, I will need to make an interface for each site because of the different vlans, then once I put the AP's in H-REAP mode I will need to assign them to the correct VLAN and this will broadcast the SSID?
By default, all wlans with wlan id 1-16 will be placed in the dafault-group. This group will have all ssids that you create with wlan id 1-16. So all these will be activeap's will default to the default-group. You have to configure each h-reap/flexconnect ap to assign what wlan ssid you want to map to what vlan at the remote site.
What I am trying to avoid is having to create multiple AP groups, I will have multiple sites with the same SSID but will be on different vlans and networks.
if you are going to use HREAP for the sites, you don't need to create AP groups, just HREAP groups if you are using 802.1x.
All you need to do is map the appropriate VLAN for the AP at the site.

You don't need AP Groups... If your ap's are in h-reap, you need to manually configure each ap. WLAN 1 is mapped to vlan 100, WLAN 2 is mapped to vlan 101, etc. H-REAP is different form AP GRoups....
Well right now we are not using 802.1x, just WPA2 AES. We need to use H-REAP because of the encryption abilities of H-REAP because we are a healthcare provider. We will be moving to 802.1x soon but that could be next year. Since we are not using 802.1x do we need to use AP groups?
You don't need to use AP Groups.
Here is a video on h-reap.... this is what you need to do.
