Legacy Cisco IP Phones on ArubaOS-CX

    Hey all,

     

    We recently got our first ArubaOS-CX switch in (Aruba 6300) and I'm having trouble getting our old Cisco 7960 IP phones working properly after the following commands:

     

    cdp enable

    vlan 5

    vlan 10

    voice

     

    int 1/1/1

    no shutdown
    no routing
    vlan trunk native 5
    vlan trunk allowed 5,10
    power-over-ethernet pre-std-detect
    exit

     

    At first, the phones will come up fine, and the access port will work and be on the correct VLAN for a desktop connected to the phone. However, after a couple of minutes, the phones will then revert to, "Configuring IP," and never move past that. The connected desktop still works fine. It's as if some timer expired relevant to the phone's VLAN/connectivity. The only relevant log I can see are these lines repeating (1/1/48 is the untagged vlan1/trunk/uplink port):

    Anyone run into this? Am I not configuring a VoIP port correctly for ArubaOS-CX?

    configuration looks correct, what CX version of code are you running?

    whats the output of  "show mac-address-table vlan 10" ?
