Configure bonding for IEEE 802.3ad (Link aggregation)

For details about bonding in general, see the Linux Ethernet Bonding Driver HOWTO

This article is the counterpart of port-channel.

Debian

• /etc/network/interfaces

  auto bond0
  iface bond0 inet static
  address 192.168.0.10
  netmask 255.255.255.0
  slaves eth0 eth2
  bond_miimon 100
  bond_mode 802.3ad
  bond_lacp_rate fast
  
  
  allow-bond0 eth0
  iface eth0 inet manual
  
  
  allow-bond0 eth2
  iface eth2 inet manual
  

RedHat (CentOS, Scientific Linux, Fedora, ...)

For users of a ixgbe (Intel) nic: Careful with kernel releases between 2.6.194-8.1.el5 and 2.6.18-229.el5, you might run into RHEL bug #619070

• /etc/sysconfig/network-scripts/ifcfg-bond0

  DEVICE=bond0
  IPADDR=192.168.2.12
  NETMASK=255.255.255.0
  ONBOOT=yes
  BOOTPROTO=none
  USERCTL=no
  BONDING_OPTS="miimon=100 mode=802.3ad lacp_rate=fast"
  

• /etc/sysconfig/network-scripts/ifcfg-eth0

  DEVICE=eth0
  BOOTPROTO=none
  ONBOOT=yes
  HWADDR=xx:xx:xx:xx:xx:xx
  MASTER=bond0
  SLAVE=yes
  USERCTL=no
  

• /etc/sysconfig/network-scripts/ifcfg-eth1

  DEVICE=eth1
  BOOTPROTO=none
  ONBOOT=yes
  HWADDR=xx:xx:xx:xx:xx:xx
  MASTER=bond0
  SLAVE=yes
  USERCTL=no
  

OpenSUSE

Presumably the same issue with the kernel as for RedHat. I haven't got it to work with 2.6.27.7-9-default (openSUSE 11.1).
