Flex mode AP2802: Problems with DHCP radius enabled SSID.

[Brendan Marmont]

We are currently in the phase of deploying new access points at a remote site. The site has had AP 3500s till now. It has no issues with clients connecting over a radius enabled SSID. Both new and old access points are connected to WS3650-24PD switch with SW version 03.06.05E.

The WLC is Cisco 5508 with version 8.2.141.0 updated in December last year.

Am I missing anything obvious? The client just do not get the DHCP enabled address and end up getting a self assigned (169.254.x.x) address with no network connectivity. Any help around this would be appreciated.

Any of you able to get Flex connect working with new AP2802 & radius enabled SSID? Any inputs/suggestions will be greatly appreciated.

Thanks.

Also tried disabling 5Ghz radios but no help

Still testing but I think we may have found some resolution with regards to this issue. Clients can connect to the SSID okay now.

 After reading a bit about the switch port configuration.
I disabled the native vlan tagging on the switch which allowed.  (http://www.cisco.com/web/techdoc/dc/reference/cli/nxos/commands/l2/vlan_dot1Q_tag_native.html)

Note: The vlan dot1q tag native command is enabled on global basis.
