Hello,
The port based VLAN configuration section is simply not necessary. Due to its switch architecture TCR100 WAN port is separated from switch configuration, thus switch functions are not needed.
As for wireless clients accounting, the device does not have an internal RADIUS server, but you can use the Hotspot feature to configure users, user groups as well as other connection related settings. Please check this page for more details regarding the Hotspot.
Best regards,
