Description

The miimon bond option must always be set to detect failures properly. As stated by bonding.txt

It is critical that either the miimon or arp_interval and
arp_ip_target parameters be specified, otherwise serious network
degradation will occur during link failures. Very few devices do not
support at least miimon, so there is really no reason not to use it.

About miimon option:

Specifies the MII link monitoring frequency in milliseconds.
This determines how often the link state of each slave is
inspected for link failures. A value of zero disables MII
link monitoring. A value of 100 is a good starting point.
