      I have a Bond0 interface and its currently in lacp mode. There are another set of systems that i want to set up a Bond0 interface but set it up for active-backup.

      In vmware you can have a port-group (network) assigned to uplinks and those uplinks can be set up for Teaming , active/standby which is different from lacp. It would be helpful to have that option available in the GUI.
      I can most likely adjust this to a current Bond by using the xe cli commands but it should be availabe in the GUI.

        I measured this on a two-NIC 8.3 host.
        As far as I understand, there's no way to do it from XO: the call that edits a network doesn't take a bond mode, every bondMode in the codebase sits on a create path, and the REST API on a running XOA offers create_bonded_network plus get and delete on a network, with nothing that edits one. 🤷
        The CLI route looks cheap though. xe bond-set-mode on a live bond cost zero dropped packets in both directions I tried, pinging every 200ms across the change, and the command returned in about 1.4 seconds.

        Two caveats, and the second is about your case specifically: creating and destroying the bond did interrupt the host (roughly 8 and 16 seconds), and I only went active-backup to balance-slb and back, never touching lacp, because my switch port isn't configured as a LAG and I'd have dropped the box.
        So I can't tell you your lacp to active-backup move is free, only that mode changes in general didn't cost me anything.

        Worth putting on https://feedback.vates.tech either way so the votes have somewhere to gather.
