Links

Commands and tools

ip link

ip link set dev bond0 etc etc

manpage: The interface in question does not support MII queries. Most likely, it does not have MII transceivers, at all.


Debugging

cat /sys/devices/virtual/net/bond*/
cat /sys/class/net/bond0/bonding/miimon

FAQ

change bonding type

only works when the bonding interface is down

ip link set dev bond0 type bond mode active-backup

or

echo 6 > /sys/class/net/bond0/bonding/mode

or

echo balance-alb > /sys/class/net/bond0/bonding/mode

MII Status: down

bond0: link status definitely down for interface ens1f0, disabling it
