3200 Controller, wlan DHCP issue

  • 1.  3200 Controller, wlan DHCP issue

    Posted Jan 24, 2014 03:56 AM

    I have a 3200 controller with aruba os 6.1.1.3 managing one ap 105.

     

    When i connect an mobile phone or a computer. I can see that it is authenticated and receive an ip adress. Now I try to connect a new device, the authentification is ok, i can see it in the controller. But it appears only the mac adress and no ip.

     

    How and when can I start to debug it ?

    Can you please share the show user-table | include <device Mac>

    What type authentication are you using?

    You can turn on logging debugging user-debug <device Mac>
    Show log user-debug 50

    The authentification is a WPA2 PSK with AES. In the controller I can look it's authentificated.

     

    The show user table gives nothing :

     

    Users -----     IP           MAC       Name   Role  Age(d:h:m)  Auth  VPN link  AP name  Roaming  Ess id/Bssid/Phy  Profile  Forward mode  Type ----------  ------------  ------  ----  ----------  ----  --------  -------  -------  --- ------------  -------  ------------  ----

    Enable the following to see the dhcp process :

     

    logging debugging network subcat dhcp

    show log network all | include <device mac>

    From where can I enable it ? From the command line in putty or into the webinterface ?

     

    Best regards.

    Are you using internal of external DHCP server?
    if internal, make sure that DHCP service is enable.

    A user requires an ip address and mac address to get into the user table.  If it did not get an ip address, it will not end up there.  Where do you have DHCP running in your environment?

    The DHCP is enabled for ipv4 and v6. I think i found the issue. The ssid encryption is 
       opmode wpa-psk-tkip

    Normally we have to do it in wpa2-psk-tkip.

    Seems like authentication issue on layer 2 cause the IP DHCP issue. Do a show auth trace-buff and see if client is having any autehentication issue.
