Connectivity problems between Aruba 3810M and Cisco 6880x

  • 1.  Connectivity problems between Aruba 3810M and Cisco 6880x

    Posted Mar 14, 2018 05:33 PM

    We are trying to get a Cisco 6880x to connect with an Aruba 3810M.

    After connecting the fiber between them the link shows up with no errors, but the Aruba side shows transmit packets being dropped.

    From the Aruba side LLDP and CDP shows info for the Cisco switches.

     

    I have searched the internet for the past 2 days and had 3 others look at it and still cannot get it working.

     

    Any help or insights are much appreciated.

     

    Here are the configs for the Cisco and Aruba switches.

     

    Cisco 6880 config

    I see that port security has been enabled at the interfaces to the Cisco switch. Please try to disable this. Also make sure that the interfaces are not blocked by stp.
