VLAN and SSID

[Antonio Matera]

Hallo,
now I have the users configured as follow:

user1    Auth-Type := EAP
            Cisco-AVPair := "ssid=SSID1",
            Tunnel-Medium-Type = IEEE-802,
            Tunnel-Private-Group-Id = 2,
            Tunnel-Type = VLAN

user2    Auth-Type := EAP
            Cisco-AVPair := "ssid=SSID2",
            Tunnel-Medium-Type = IEEE-802,
            Tunnel-Private-Group-Id = 3,
            Tunnel-Type = VLAN


The AP has the radius-server vsa send authentication, but when I connect 
for example to the SSID2 using user1, radius write this log for a big 
number of request:


rad_recv: Access-Request packet from host 192.168.9.104:1645, id=167,

Finished request 53



The XP client tell that the SSID2 is connected, but if I try to navigate 
on the VLAN1 or VLAN2 i can't do it.

Why the radius receive a big number of request from the client and it 
doesn't sent a failed authorization? It is possible to eliminate the 
requests after the first?
It is possible to send to the XP client a failed authorization? At the 
moment the client doesn't understand  if it is or isn't connected to the 
SSID.



Thanks a lot for your time
Bye Antonio
