Client ARP Request not working behind VA MC AOS 8.2.0.2

  • 1.  Client ARP Request not working behind VA MC AOS 8.2.0.2

    Posted Mar 06, 2018 11:42 PM

    Hello together,

     

    I currently have a strange problem with my new AOS 8.2.0.2 infrastructure. I have a wireless client behind a AP which is connected to a Virtual Mobility Controller. The client can connect to the SSID and gets without  problems all DHCP information.

    But when I now try to ping the given default gatway on this client, I can't reach them.From the  virtual controller I can reach the gateway.

     

    I already create a packet capture on the controller and saw this

     

    #show packet-capture datapath-pcap
    
    14:58:24.316589 IP 10.217.12.28 > 10.104.47.248: GREv0, length 82: gre-proto-0x8210

    I have the follwing setting on the virtual-ap

    I'm also not able to ping from the controller to the wireless client.

    Has someone a idea?

     

    Thanks for your help!!!

    Sorry to dig up an old thread, but did you ever find a solution to this? We are having a very similar issue in our environment. I have a TAC Case open, but not much progress has been made. Was wondering if there is anything I should be looking at?

    Thanks,
    Chris
