Hi Everyone, Dave, Are you sure the command aaa authentication network default group radius is valid on 2950 switches ? I am running Version 12.1(22)EA5, which was the last stable image in july and "network" is not available as aaa authentication option. If anyone has met any success with dynamic VLAN assignment on Cisco 29502 with FreeRadius. I am interested ! Here is how my user is declared: Client_Arpege Auth-Type := EAP Service-Type = Framed-User, Reply-Message = "Authentification OK - Bienvenue sur le RCSG", Tunnel-Type = :1:VLAN, Tunnel-Medium-Type = :1:6, Tunnel-Private-Group-ID = :1:140 :1: are used to give tags a value of 1, 6 is interprested by FreeRadius as IEEE-802. I have checked with Ethereal and the paquet sent seems OK. I think the problem comes from the switch. Here is the configuration file: ! version 12.1 no service pad service timestamps debug datetime msec localtime service timestamps log datetime msec localtime no service password-encryption ! hostname Switch802_1x ! aaa new-model aaa authentication login default group radius local aaa authentication dot1x default group radius aaa authorization exec default group radius if-authenticated aaa accounting dot1x default start-stop group radius enable password ******** ! username admin secret 5 $1$IqQs$tJ9S4pfeDfZR42vlaFrbQ1 ip subnet-zero ! ! spanning-tree mode pvst no spanning-tree optimize bpdu transmission spanning-tree extend system-id dot1x system-auth-control ! ! ! ! interface FastEthernet0/1 switchport access vlan 136 switchport mode access spanning-tree portfast ! interface FastEthernet0/2 switchport access vlan 136 switchport mode access spanning-tree portfast ! interface FastEthernet0/3 switchport access vlan 136 switchport mode access spanning-tree portfast ! interface FastEthernet0/4 switchport access vlan 136 switchport mode access spanning-tree portfast ! interface FastEthernet0/5 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/6 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/7 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/8 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/9 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/10 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/11 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/12 switchport access vlan 141 switchport mode access switchport port-security switchport port-security mac-address sticky switchport port-security mac-address sticky 0001.e6a7.09d8 spanning-tree portfast ! interface FastEthernet0/13 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/14 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/15 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/16 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/17 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/18 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/19 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/20 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/21 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/22 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/23 switchport mode access dot1x port-control auto spanning-tree portfast ! interface FastEthernet0/24 switchport trunk native vlan 136 switchport mode trunk ! interface GigabitEthernet0/1 ! interface GigabitEthernet0/2 ! interface Vlan1 no ip address no ip route-cache shutdown ! interface Vlan136 ip address XX.XX.XX.XX 255.255.255.0 no ip route-cache ! ip default-gateway YY.YY.YY.YY ip http server logging trap notifications logging facility local6 logging ZZ.ZZ.ZZ.ZZ radius-server host ZZ.ZZ.ZZ.ZZ auth-port 1812 acct-port 1813 key testing123 radius-server retransmit 3 ! line con 0 exec-timeout 0 0 password ******** line vty 0 4 exec-timeout 0 0 password ******** line vty 5 15 exec-timeout 0 0 password ******** ! ! end The Client is connected to port 0/23 which is dot1x enabled.
