VLANs (NOT dynamic) with Radius

Installing and Using OpenWrt
1

Hi,

I have router with openwrt and server with freeradius. Can I on Openwrt add own attribute that contains in which VLAN is my device, and then check it on RADIUS server?

For example I want to add do RADIUS frame {VLAN: '5'}, and then check it on server like this:
xs

Thanks.
