Authentication failed for Network Login MAC user

There is old EXOS switch X430-8p, it does not support Extreme Policy, but it supports netlogin and UPM features. I configured UPM profile in switch, Policy and Rule at NAC, also inserted UPM profile name at port profile at NAC.

At NAC End-Systems table End-System is successfully authenticated and gets correct Profile:
( tcpdump created PCAP file ) RADIUS sends toward the switch:
Vendor-ID: 0x0000077C = 1916 (Extreme Networks)
Vendor-Type: 0xD4 = 212
Vendor-Length: 0x14 = 20
Vendor-Data: "UPM_VLAN_Printerid"

Switch log shows:
07/02/2026 14:19:26.01 <Info:nl.ClientAuthFailure> Authentication failed for Network Login MAC user D4B4C0622270 Mac D4:B4:C0:62:22:70 port 1

i used the 'RADIUS Attributes to send' -> 'Extreme Netlogin - VLAN Name' at NAC

Does anyone have this ( netlogin + UPM without Policy at EXOS switch ) setup working and what 'RADIUS Attributes to send' is in use ?
