mode=

Possible values are 0 (round robin policy, default) and 1 (active backup
policy), and 2 (XOR). See question 9 and the HA section for additional info.

miimon=

Use integer value for the frequency (in ms) of MII link monitoring. Zero value
is default and means the link monitoring will be disabled. A good value is 100
if you wish to use link monitoring. See HA section for additional info.

downdelay=

Use integer value for delaying disabling a link by this number (in ms) after
the link failure has been detected. Must be a multiple of miimon. Default
value is zero. See HA section for additional info.

updelay=

Use integer value for delaying enabling a link by this number (in ms) after
the “link up” status has been detected. Must be a multiple of miimon. Default
value is zero. See HA section for additional info.

arp_interval=

Use integer value for the frequency (in ms) of arp monitoring. Zero value
is default and means the arp monitoring will be disabled. See HA section
for additional info. This field is value in active_backup mode only.

arp_ip_target=

An ip address to use when arp_interval is > 0. This is the target of the
arp request sent to determine the health of the link to the target.
Specify this value in ddd.ddd.ddd.ddd format.

If you need to configure several bonding devices, the driver must be loaded
several times. I.e. for two bonding devices, your /etc/conf.modules must look
like this:

alias bond0 bonding
alias bond1 bonding

options bond0 miimon=100
options bond1 -o bonding1 miimon=100
