I have been testing vlan configuration using radius.
I have a profile to set ULMIR, DLMIR, STAPRI, and VLDatatPVID.
The attributes are being sent according to freeradius debug,
Sending Access-Accept of id 84 to 64.90.xx.xx port 48420 Cambium-ePMP-DLMIR := 10248 Cambium-ePMP-ULMIR := 2048 Cambium-ePMP-VLDataPVID := 1222
Cambium-ePMP-STAPRI := 4
but when I check the SM after registering, I find no data vlan is set and the data vlan priority is configured with the vlan id. I haven't actually checked the functionality of the data vlan, just checked the page in the GUI.
Have you set Cambium-ePMP-VLIGVID? That's the Data VLAN VSA. I'm asking because I don't see it listed in your post. Cambium-ePMP-VLDataPVID is the Data VLAN priority which should be between 0 and 7. I think you want to set Cambium-ePMP-VLIGVID as 1222.
