MAC based authentication

[Chun (Andrew) Xu]

I forgot to mention one thing.  I am using VLAN name instead of VLAN ID to do dynamic VLAN assignment.  It works for me.  You could try the followings.

aa00007f9c90    Auth-Type := "EAP", Cleartext-Password == aa00007f9c90
        Tunnel-Type = VLAN,
        Tunnel-Medium-Type = IEEE-802,
        Tunnel-Private-Group-Id = "PRIV0"

I thought I'd. Indeed authentication is working now, however the switch doesn't assign clients to the VLAN the RADIUS server instructs to. May be off-topic, but would you mind give me hint?

The EX monitor output gives me:

However:

 None

That's odd, since I think I did everything appropriate. A snippt from configuration:
