802.1X authenticated ports are assigned to a VLAN that is based on the username of the host that is connected to the port. VLAN assignments work with the RADIUS server, which has a database of username-to-VLAN mappings. After a successful 802.1X authentication of the port, the RADIUS server sends the VLAN in which the user needs to be given access.
Architecturally, performing the VLAN Assignment by name mitigates this concern and allows for flexibility in this regard. 802.1X should not require you to build a specific VLAN/VTP architecture for subnetting. Ideally, it should work with what you already have. This is supported on all Cisco Catalyst switches.
