From https://documentation.meraki.com/MR/Client_Addressing_and_Bridging/RADIUS_Override:

A RADIUS server has the ability to send VLAN information to the AP in RADIUS Access Accept messages. To send VLAN information, three required RADIUS attributes must be configured in your RADIUS policy:

• Tunnel-Type: Choose Attribute value Commonly used for 802.1X and select Virtual LANs (VLANs).
• Tunnel-Medium-Type: Choose 802 (Includes all 802 media plus Ethernet canonical format) for the Attribute value Commonly used for 802.1X.
• Tunnel-Private-Group-ID: Choose String and enter the VLAN desired (ex. "500"). This string will specify the VLAN ID 500.

Sample FreeRADIUS user configuration (/etc/freeradius/3.0/users):
