Looking under the hood, it's actually handled by the /etc/sysconfig/network-scripts/ifup-eth script, which writes the values to the pseudo-files under /sys/class/net/bondX/bonding/, so there you go, another way to change that dinamically without having to restart the interface. Would you be kind to see if you can change the primary "on-the-fly" using this method? Thanks, Filipe
