Ola Marcelo!
Em Local Web Authentication, o SSID é configurado com segurança de Nível 3 no WLC e será o WLC a apresentar a página de login ou a redireccionar para um URL externo predefinido no WLC. O utilizador recebe a página de login, e as credenciais são verificadas pelo WLC utilizando a base de dados local, ou externa usando RADIUS ou LDAP.
Em Central Web Authentication, o SSID é configurado com segurança de Nível 2 no WLC, utilizando Mac Filtering e Radius NAC. Quando o utilizador se liga na rede wireless, o WLC envia o endereço MAC da máquina do utilizador para o ISE e o ISE retorna um endereço e ACL de redireccionamento para o WLC applicar à máquina do utilizador. O utilizador fará de seguida o login na página de login do ISE, e após autenticação bem sucedida, o ISE enviará RADIUS CoA (Change of Authorization) para o WLC permitindo a ligação do utilizador.
Cumps,
Tiago

Nos dias que correm a maioria de empresas possuem uma rede wireless e desejam permitir acesso a visitantes. Neste sentido surgiu o modelo the Central Web Authentication onde qualquer visitante pode ligar o seu dispositivo pessoal a rede Wireless e obter uma pagina de login central num servidor RADIUS onde se autenticara com as credencias de visitante.
Neste "Pergunte ao Especialista", o Tiago estará respondendo as perguntas relacionadas com CWA com WLC e ISE.
Faça suas perguntas de segunda-feira, 23 de Maio a sexta-feira 03 de Junho de 2016

Ok, so you had missed to include the VLAN 5 in the allowed VLANs of the trunk? Please note that in this kind of setup when you have multiple VLANs in an interface, it is a trunk and only the allowed VLANs are able to pass traffic through it. I am not sure what you mean by "dot1 with a different IP address when I put a PC in August vlan vlan works"...? BR, Tiago

Indeed, AP config looks ok so most likely the VLAN 5 is not allowed in the trunk... Can you check the switchport configuration or share it with us and we can check. BR, Tiago

Hi, Can you send us the complete sh run from the AP and the switch where the AP is connected? Where is the DHCP server located? Do you have a DHCP pool created for the VLAN assigned to the SSID testing? If you connect a PC in the switch and place the switchport in the same VLAN, does it get IP address? HTH, Tiago -- If this helps you and/or answers your question please mark the question as "answered" and/or rate it, so other users can easily find it.

Hi, From those logs, we can see that your SSID requires authentication and this authentication is against a RADIUS server which is configured on the AP with RADIUS server ip address 20.33.100.11. However, this RADIUS server is not replying to the RADIUS Access-Request packets that the AP is sending. So after 5 tries, the AP gives up and reports that the authentication is failed. I would check if the RADIUS server is running and if properly configured to accept connections from this AP. HTH, Tiago -- If this helps you and/or answers your question please mark the question as "answered" and/or rate it, so other users can easily find it.

Hi, Can you please be more clear with "not working"? What exactly is not working? What do you see in the SSIDs that work that you do not see in the SSID that does not work? Which one does "not work"? The configuration you attached is not complete... however in the dot11 radio configuration i can see: ssid CISCO_2.4GHZ_Guest ! ssid CISCO2.4GHZ_Private ! ssid CISCO_2.4GHZ_Study ! ssid CISCO_2.4GHZ_Testing Shouldn't it be "ssid CISCO_2.4GHZ_Private" instead of "ssid CISCO2.4GHZ_Private"? Please note the missing underscore compared with the other SSIDs. HTH, Tiago -- If this helps you and/or answers your question please mark the question as "answered" and/or rate it, so other users can easily find it.

Hi Wagas, Can you please clarify exactly what will be the relation with NAc and the Wireless network? Do you which to make the wireless users to go through NAC before accessing the network? Are you looking for an InBand or Out Of Band setup? I would advise you to take a look into this chapter of the configuration guide where you can see a comparison between the diferent kinds of deployemnts for Wireless NAC: http://www.cisco.com/en/US/docs/security/nac/appliance/configuration_guide/48/cam/m_woob.html#wp1040103 .

Hi Bryan, From the log messages: 2011-06-06 09:37:21.832 -0400 ERROR com.perfigo.wlan.jmx.adsso.GSSServer - Unable to start server ... Password has expired - change password to reset (23) It looks like the password has expired... I would check if indeed the password has expired, or simply change the passowrd, mark the checkbox to "password never expires" and re-run ktpass.

Hi Bruce, I am afraid there are some arguments missing in your db command. To manually add the OID of Cat4507R+E to CAM's database here is the procedure to do this. [root@cca-3140-cam ~]# psql -h localhost -U postgres controlsmartdb -c "INSERT INTO supported_switch VALUES ('1.3.6.1.4.1.9.1.1286', '4', 'Cisco Catalyst 4507 R+E')" INSERT 0 1 psql: warning: extra command-line argument "INSERT" ignored psql: warning: extra command-line argument "0" ignored psql: warning: extra command-line argument "1" ignored INSERT 0 1 Then to make sure it is there: [root@cca-3140-cam ~]# psql -h localhost -U postgres controlsmartdb -c "SELECT * FROM supported_switch" | grep 1286 The output should be: 1.3.6.1.4.1.9.1.1286 | 4 | Cisco Catalyst 4507 R+E Restart perfigo service on NAC Manager and try to manage the switch using the model used by the above command. HTH, Tiago -- If this helps you and/or answers your question please mark the question as "answered" and/or rate it, so other users can easily find it.

Hi Bruce, Thanks for your post. 4507E switches is already supported as we can see in Table 11 "Supported Cisco Catalyst 4000/4500 Switches". So you should not need to do any DB change... We surelly can help you but i kindly ask you to create a new discussion out of this one which is meant for AD SSO setups. When creating the new discussion, please let us know what exactly happens when you are trying to add the switch to the CAM. What error messages you get and what is the switch and CAM snmp configuration. Thanks, Tiago

Hi, Well, the failed attempts and auth ok are for different users... So I am not sure what is the relation between these different users, but one thing for sure is that the "badcrew" either does not exist in the External DB or you are entering the worng password... HTH, Tiago

Hi again, The troubleshooting tips i gave you are the ones you should follow. With the sniffer traces (and not those cli outputs) you will be sure if the DHCP packets are or not on the untrusted/trusted interfaces. These are the troubleshooting steps you should follow... Good luck. Tiago
