  • 1.  LLDP-MED, RAP 505H, AOS 8.7.0.0, Cisco Voip Phone

    Posted Aug 12, 2020 11:34 AM

    Can't get lldp-med to work with Cisco 8961 voip phone using a 505H RAP solution with AOS 8.7.0.0 on controllers.
    I set E1 as a trunk with native vlan for data and allowing a vlan that is used for voice. If I hard set the admin vlan on the phone to the tagged voice vlan the phone works fine. But all attempts to get lldp-med to configure the phone (checked, it supports lldp-med according to Cisco with the version of software running on the phone) fail.
    Sniffing the LLDP packets shows me that the TLVs are not present to the phone. I can manipulate the TLVs using the LLDP profile to the phone and see them change in the sniff, but the LLDP-MED TLVs never appear.

     

    Here are the relevant configs:


    ap wired-ap-profile RAP-WiredAP
    wired-ap-enable
    trusted
    switchport mode trunk
    switchport access vlan 2002
    switchport trunk native vlan 2002
    switchport trunk allowed vlan 100,2002
    !
    ap lldp profile RAP-LLDP-Voice
    optional-tlvs
    dot3-tlvs
    lldp-med-network-policy-profile RAP-Phone-LLDP-Med
    lldp-med-tlvs capabilities inventory network-policy
    !
    ap lldp med-network-policy-profile RAP-Phone-LLDP-Med
    vlan 100
    tagged
    l2-priority 5
    dscp 46

    Everything works fine except for the media endpoint discovery stuff.

     

    In the end I set up port E2 to be access vlan 100 and the phone works fine. That may be all I can do for now, but it would be nice to get LLDP-MED working.

     

    Am I missing something? The last real discussions on Airheads that I can find of this were years ago with AOS6 ... It just looks to me like the AP is not sending the TLVs as the profiles direct.

     

    Starting to get lots of requests for RAP solutions. Thanks for any help before I call TAC ...

    Update: This works with same config with a 303H RAP, all the way up to AOS 8.7.0.0.

     

    It appears that the 505H (Gemini) firmware needs some TLC from the programmers.

    Please feel free to open a technical support case so we can determine if it is your setup, the software or the hardware that is causing this issue.

    Appreciate the sentiment, this is the result of a TAC case.

     

    I replaced the 505H with a 303H as requested by them and it works with no modifications in the configuration.
