I've setup a link aggregate of the two ethernet ports on my macpro6,1 (via System Preferences > Network > Manage Virtual Interfaces > New Link Aggregate).
Due to the way my other devices are setup, I need to set the "bondmode" of my device to "static":
$ sudo ifconfig bond0 bondmode static
The problem so far is that, for no reason that I can discern and triggered by nothing I can identify in the logs, the bondmode reverts back to "lacp", and all of my connections drop.
I can trigger this myself via
networksetup -createbond xxx to create an extra (broken) bond. So perhaps changes to the network setup in general reset it to LACP?
Is there something I can do to stop whatever process is causing the bondmode to change, or somehow achieve this another way? My end goal is to get some sort of round-robin style pattern for sending packets to spead a single connection across both ethernet cables to my server, as LACP results in all packets from a given connection going through a single link.
