    Posted Dec 09, 2015 04:50 AM

    Hi all,

    I have some trouble getting ap-277's to work properly on a Cisco WS-C2960S-48FPS-L. I think it is the software version that is the problem, but I don't know for sure.

    The problem is that the ap's don't advertise any radio because of LLDP not negotiating the POE settings.

     

    Output of a "show ap debug system-status <ap-name> | begin "Power Status" " on the Local Controller:

    Power Status
    ------------
    Operational State POE-AF: Ethernet port 1 disabled; All radios disabled;
    ----------------- ------------------------------------------------------
    Current HW State POE-AF: Ethernet port 1 disabled; All radios disabled;
    LLDP Negotiated POE Power 0.0W

     

    Output of "show lldp neighbor <interfacename> detail" som output has been blocked with ****:

    Chassis id: ****
    Port id: ****
    Port Description: eth0
    System Name: ****

    Power Device Type: 2
    Power Source: PSE
    Power Priority: Unknown
    Power Requested: 25500 mW


    Total entries displayed: 1

     

    I also have a AP-277 that does work. It is on another switch with a higher software version.

    When I debug the LLDP traffic on the switch where the ap-277 does not work, I get the following messages in the log of the switch:

    13333021: Dec 9 08:41:37.964 CET: LLDP unknown tlv type 127 recd - ignoring it
    13333022: Dec 9 08:41:37.964 CET: LLDP malformed optional TLV 127 found - ignored

     

    I don't get these messages on the switch where the ap-277 does work.

    Any suggestions?

    You likely need to upgrade the siwtch version to the latest code, Cisco had some issues with early IOS versions that didn't properly recognize LLDP frames. You could also try to just enable max power on the switch, there's been a few posts within the AirHeads community on that, but Iwould upgrade the switch IOS first.
