Some days ago, I updated our 5508 WLC to software version 188.8.131.52.
With that version, it should be possible to have a VLAN mapping specific for a Flexconnect group that is set within Flexconnect Group settings.
I did that for all my Flexconnect groups and it works fine with new access point.
For existing access point, which already have an AP-specific VLAN mapping, it is not possible to switch to Group-specific.
When I mark the WLAN in Flexconnect setting of the AP and select "Remove AP specific", I get the error message "Request failed: Vlan is not enabled on this flexconnect".
I wonder what the problem could be, because for newly installed access points, it works fine. Did I miss some settings?
