    Hi

    We have an issue that some ports show the same MAC address with different VLAN "Voice & Data" as the below screenshot, we connect the IP phone to the switch and data to PC through the IP phone while other ports working normally with the same installation and all the ports that configure with ClearPass and show 3 MAC address make an err-disabled.

    Appreciate your help

    Thanks

    I believe this is normal for a device that changes VLAN through CoA. The MAC table should age out the old VLAN 8 entry. What are the logs saying for the err-disable reason?
