Ethernet Bonding on Debian Squeeze

Spent a few minutes searching for a howto for setting up ethernet interface bonding on a new file server I’m building today. Nothing special but I found a bunch that aren’t that great … I know, welcome to the internet right? But I did find one that’s awesome from tuxhelp.org.

My final config went like this:

echo -e "bondingnmii" | sudo tee -a /etc/modules

With an /etc/network/interfaces file that looks like this:

auto lo bond0
iface lo inet loopback

iface bond0 inet dhcp
    bond_mode balance-rr
    bond_miimon 100
    bond_downdelay 200
    bond_updelay 200
    slaves eth0 eth1

What was lacking in all other (even Debian specific) howto’s is that they always use direct invocation of ifenslave and pass options to the bonding driver manually. IMHO it’s so much nicer to use the facilities built in to ifup like the slaves option instead of using something like:

up /sbin/ifenslave bond0 eth0 eth1

That said I haven’t had much luck finding documentation for options like this specific to a driver and how to use them in the interfaces file. Given the above example I can guess but I’m looking for a definitive source … Anyone out there know?
