how to create AP Groups in WLC 9800

[DayibQalib25577]

I have 100 APs in in 6 different  locations , each location will have its own subnet  but  need APs   broadcasting same SSIDs in the WLAN profile

You make then different AP Group and assign the IP address, if you doing same place, roaming will have issue, since IP subnet changes.

Thanks that link was really self explanatory

Here is the high level flow:

Local mode APs:
Define/Create VLANs or SVIs for wireless VLANs on WLC.
policy profile - Create policy per each WLAN and from drop down select the VLAN-id/interface.
on site tag(==AP group), map WLAN to policy-profile(that has appropriate VLAN-id) for that site as stated in flex profile.
Repeat for all WLANs and for other sites.

Flex mode APs:
Create flex group/flex site, per site. configure/define VLANs that will be used in that site.
policy profile - Create policy per each WLAN and manually type VLAN-id.
on site tag(==AP group), map WLAN to policy-profile(that has appropriate VLAN-id) for that site as stated in flex profile.
Repeat for all WLANs and for other sites.

Aireos Vs IOS-XE interpretation:
Aireos IOS-XE
WLAN WLAN that has only radio-related config.
XXXX policy profile that has extended WLAN config along with VLAN mapping.
