Should it though? That will, for example, terminate any tcpdump processes bound to the bond, it will disrupt currently running connections, etc. Maybe we could do it but we'd want to put it behind a --force option or something, I think.

If I change that in the yaml, then run # netplan generate # netplan apply # cat /proc/net/bonding/bond0|grep "MII Polling Interval (ms)" MII Polling Interval (ms): 1000 In other words, the change has not been applied. Running netplan --debug apply prints: DEBUG:device bond0 operstate is up, not replugging So I wondered if bringing the bond down would help. It does not: # ip link set dev bond0 down # netplan apply # cat /proc/net/bonding/bond0|grep "MII Polling Interval (ms)" MII Polling Interval (ms): 1000 However, deleting the link works: # ip link del dev bond0 # netplan apply # cat /proc/net/bonding/bond0|grep "MII Polling Interval (ms)" MII Polling Interval (ms): 2000 This is counter-intuitive behaviour. Ideally, I would like a regular netplan apply to work without deleting the bond. However, a changed to the docs to make this clear would be OK.
