Does Flex Connect mode support Radius Airespace attributes?

[Cheng]

Hi Experts,

We are testing flex connect + local switching + AAA override and having trouble in dynamic VLAN.

Radius server authorizes the client with an interface-group-name. The client should be put into VLAN 25, but suddenly, it is quarantined in mgmt VLAN 11.

I wonder if flex connect mode supports radius airspace attributes? I have read the configuration guide but didn't find the restriction.

Hi

 I dont believe this is related to flexconnect but it is easier to verify. You can change your mode to local mode and see if this problem goes away. 

 Take a look on the WLAN Advanced tab, and make sure "aaa override" is checked.

Good video on how to do this here https://www.youtube.com/watch?v=l8b8SCdphJo 

Details in this guide as well: https://www.cisco.com/c/en/us/support/docs/wireless/flex-7500-series-wireless-controllers/112973-flex7500-wbc-guide-00.html#override

Radius attribute needed:

Tunnel-Private-Group-ID=VLANID

Tunnel-Type=VLAN

Tunnel-Medium-Type=802

WLAN Config Required:

AAA override enabled

Flexconnect local switching

AP Config:

Must be in Flexconnect mode, with VLAN Support enabled

Flexconnect Group Config:

Native VLAN defined

AAA VLAN-ACL Mapping with the VLAN you want to override to in it (don't worry about defining the ACLs)

Switch Config:

VLAN must be allowed on the AP trunk port.

Limitations:

A maximum of 16 VLANs can be configured in per-AP (including non-override WLAN VLANs)

Sorry for the delayed response.

Flex mode does support airespace radius attributes. But I forgot to config flexconnect template. It is necessary for VLAN Name Override to map vlan name (interface name) to vlan id in the template.
