  • 1.  TFTP issue

    Posted Jan 09, 2018 07:11 AM

    Hi,

     

    I am using a cluster of 3400 in version 6.4.4.16 with 70 APs configured and I have one problem with the TFTP protocol.

    I have PEF license but with a pemit rule any to any.

    the current SSID is configured as bridge with no firewall 

     

    I tried to use a softphone solution and the first step is to start a tftp session to download the phone information without any success.

    the desktop on the same vlan but with a wire connection worked fine

    so the problem is on AP and I captured packets , checked logs and didn't find anything.

    I tried also to perform from my laptop a tftp copy from a switch to my desktop with the same behavior.

    so the problem seems to be linked to this protocol but I don't know why.

     

    Regards

    What is the role that the user gets when the user connects to the bridged SSID?  Find out what role the user is in and type "show rights <role>" to see what policies are enforced.  In a bridged SSID, the firewall policies are enforced on the AP.  If in that role you are blocking tftp in either direction, it will not work.

    You should try changing the ap-uplink-acl to 'allowall'.  Please see here:  http://community.arubanetworks.com/t5/Remote-Networking/What-is-the-ap-uplink-acl-and-how-does-it-work/td-p/13428

     

    That restriction does not exist in a tunneled mode SSID.
