  • 1.  MAC address Flapping 2

    Posted Apr 14, 2025 12:06 PM

    Hello,

    There was one similar thread about mac flapping but not the same issue.

    For certain network setup I have a linux guest (modern 6.x kernel) which needs 2 bridged interfaces in the same network. 

    The two bridged interfaces will have different ips inside.

    This causes a strange issue that the arpwatch I have on the network keeps notifying me of nic A and nic B's macs are flapping, even if only 1 have IP configured.

    Anyone knows a solution for this?

    I also tried to configure static mac for each, exact same issue. The only resolution for now is to have a nic disconnected from the network.

    Thanks
