To use Bonding Ethernet for High-Availability (fail-over) on Debian (Woody, Sarge or Sid with a 2.4.x kernel) you need to:
- install package ifenslave-2.4
- make sure the real NICs kernel modules are loaded automatically
- edit /etc/network/interfaces to look like this:
iface bond0 inet static address 10.31.1.5 netmask 255.255.255.0 network 10.31.1.0 gateway 10.31.1.254 up /sbin/ifenslave bond0 eth0 up /sbin/ifenslave bond0 eth1
- comment the lines referring to your real NICs in the same file
- add the following lines to your /etc/modutils/arch/i386:
alias bond0 bonding options bonding mode=1 miimon=100 downdelay=200 updelay=200
