[Bug 889423] Re: 802.3ad bonding not configured correctly

[Stéphane Graber]

I'm not sure if ifupdown guarantees that an interface marked as manual
is to be brought up but that's an interesting point thing to test.

For now, can you try adding a:
 post-up ip link set dev bond0 up

And see if that indeed brings up the slaves and negociates LACP?

Title:
  802.3ad bonding not configured correctly

Status in “ifupdown” package in Ubuntu:
  Confirmed

Bug description:
  Configuring an 802.3ad bond doesn't appear to work correctly. The following entry in /etc/network/interfaces should configure an 802.3ad bond between interfaces eth2 and eth3:
  #auto bond0
  iface bond0 inet static
    address 10.191.62.2
    netmask 255.255.255.0
    broadcast 10.191.62.255
    bond-slaves eth2 eth3
    bond-primary eth2 eth3
    bond-mode 802.3ad
    bond-lacp_rate fast
    bond-miimon 100

  However, after booting the system, we have:
    # ifconfig -a
    bond0     Link encap:Ethernet  HWaddr 00:1b:21:b7:21:ea

  I can ping 10.191.62.2 after making the above changes. So, either I am
  configuring /etc/network/interfaces incorrectly or ifupdown/ifenslave
  is doing the wrong thing.

  Note also the number of dropped packages on bond0. Why should I see
  any dropped packages on the bond0 interface?
