If the master interface is not available at the time the first slave is setup, it will be created and setup according to bond* options in the slave stanza. For this reason, in order to get consistent results, the values of all the bond* options should normally be identical in the master stanza and in all the possible slave stanzas.

A bonding master is defined like this:

iface bond0 inet static

address 208.77.188.166
...
bond_slaves none

The bonding slaves should then be defined like this:

auto eth0 iface eth0 inet manual

bond-master bond0
bond-primary eth0 eth1

auto eth1 iface eth1 inet manual

bond-master bond0
bond-primary eth0 eth1
