    I read this topic, because is see the same issue on my network.
    ****************************************************************************
    lldp: ST1-CMDR: PVID mismatch on port 4/47(VID 10)with
    peer device port b0b867-c78ce0(VID unknown)(267838)
    ***************************************************************************888
    I REVIEWED THIS TOPIC ON AIRHEADS.

    https://community.arubanetworks.com/t5/Wired-Intelligent-Edge-Campus/How-To-Stop-PVID-Mismatch-Messages/ta-p/471996

    One unanswered question on the topic is:
    ********************************************************************************
    s there an equivalent for telling Access Points not to send their PVID? I am getting this everywhere I have an AP connected because the APs always report their untagged vlan as id 0.
    ******************************************************************
    I have 18 Aruba AP-315's on one switch.

    I am wondering if I should configure the switch with an AP profile or if I should follow the advice of the article
    and enter
    no lldp config 24 dot1TlvEnable port-vlan-id

    I would manually apply this command 18 times on the switch because I have 18 AP's on this switch,,, plus dozens of other switches.

    Hi Tom,

     

    You can also look on AP System Profile on MC, there is PVID / LLDP settings too

    On the Aruba controller, the AP LLDP profile can be set to not send out the pvid. The syntax is a bit strange. One would expect a ‘no dot1-tlvs port-vlan’ command, but the controller expects to get a ‘dot1-tlvs vlan-name’, which disables the other command option, that is the ‘port-vlan’ option. If that is what it expects, just do it..

    ap lldp profile "default"
     dot1-tlvs vlan-name
