  • 1.  Error logs on edge switch when client drops off Wi-Fi

    Hi Guys,

    I have been doing some log analysis on our new deployed VXLAN network, on most switches we are getting error logs that look like the following;

    <187>1 2025-06-10T13:09:12.336272+01:00 #switch name# ndmd 3979 - - debug|LOG_ERR|STBY|2|NDM|NDM_NBRMACTABLE|[nd_nbr_mgr_process_mac_phy_update_event(6589)] [PORT: vlan####| NBR: #.#.#.#| Phy-port: vxlan1] Neighbor not found. Phy port update failed.

    Does anyone have some detials on this - I can see its the Network Device Management Daemon that is reporting the error and saying the the neighbour cannot be found - yet why this is reporting that it cannot see a wireless client I cant work out.  The IP address & VLAN show me that is this a visitor to our site, I dont really need to know that they have dropped off Wi-Fi.

    Cheers!
