Issue with communication from Portal side to Point side - IAP 367

  • 1.  Issue with communication from Portal side to Point side - IAP 367

    Posted Jun 28, 2017 05:20 AM

     Hi All,

     

    I have a strange issue with the following IAP 367 Mesh Portal and Point Setup:

     

    Current Setup

     

    When traffic is initiated from any vlan on the POINT side everything works fine, however after about 5 minutes of inactivity all communication to devices behind the Point AP comes to a halt.

     

    When I try to ping devices behind the Point AP from the PORTAL side on ANY vlan they fail, when I then ping from any device/VLAN on the POINT Point side I begin to get ping replies again.

     

    If I run a persistant ping to any device behind the POINT side all communication remians up and active.

     

    I've noticed that when communication stops I can no longer see the MAC address in the Portal side Cisco switch.  

     

    It's almost as though the Portal AP stops responding to any incomming requests from the PORTAL side as the PORTAL side switch doesn't get a MAC entry in it's mac address table from the portal AP.

     

    Has anyone seen this before with the IAP Portal and Point setup?  

     

    We are using Cisco 2960 switches on both sides.

     

    Thanks,

    Adam

    You should execute "show ap mesh topology" to see the signal strength between both devices...

    Hi Colin,

     

    Thanks for your reply, I've just tried to run the command however it's not present:

     

    BAIS-ARUBA-PtP1# show ap mesh ?
    counters
    debug Debugging information
    link
    neighbours

     

    BAIS-ARUBA-PtP1# show ap mesh neighbours

    I've attached the current configurations for both APs.

     

    Cisco switch interface configurations are simple:

    Portal Switch:

    interface GigabitEthernet3/0/48
    description BAIS-ARUBA-PtP1
    switchport trunk native vlan 120
    switchport mode trunk

     

    Point Switch:

     

    interface GigabitEthernet1/0/1
    description BAIS-ARUBA-PtP2
    switchport trunk native vlan 120
    switchport mode trunk

     

     

    Thanks,
    Adam
