Use the procedures in this section to configure 802.1X or non-EAP with Fail Open VLAN.
The switch does not validate that Radius Assigned VLAN attribute is not the same as the Fail_Open VLAN. This means that if you configure the Fail_Open VLAN name or ID the same as one of the VLAN names or IDs which can be returned from the RADIUS server, then EAP or NEAP clients cannot be assigned to the Fail_Open VLAN even though no failure to connect to the RADIUS server has occurred.
