[Bug 1280366] Re: Bonding mode ignored

Tue Feb 18 08:44:27 UTC 2014

temp workaround working for me:

define bondX interface BEFORE real interface:

/etc/network/interfaces
------------------------
auto bond0
iface bond0 inet manual
  bond_mode 802.3ad
  bond_miimon 100
  bond_lacp_rate 1
  bond_downdelay 100
  bond_updelay 100
  bond_slaves eth0 eth1

auto eth0
iface eth0 inet manual
bond-master bond0

auto eth1
iface eth1 inet manual
bond-master bond0
------------------------

And then manually bring down and up the real interface (I am using
rc.local to automate this on reboot)

/etc/rc.local
------------------------
service networking restart
ifdown eth0 || true
ifup eth0 || true
ifdown eth1 || true
ifup eth1 || true
------------------------
