    openvswitch active-backup bond

    Hi there, I just noticed that the shipped version of openvswitch (2.12.x on Proxmox VE 6.3) does not yet support specifying a primary member for an active-backup bond. Unfortunately, this means that there is no clearly defined state. Newer versions (since 2.14.x, I believe) do have that...
  2. Persist OVS Port Mirror After Reboots
