Ethernet Channel Bonding Driver
The Linux bonding driver combines multiple network interfaces into a single 
logical bonded interface. The driver supports bonding modes such as failover and 
round-robin. The bonding driver also monitors link integrity. For bonding driver 
documentation, visit 
The bonding driver is a kernel-loadable module (bonding.ko) that resides in the 
/lib/modules/`uname -`/kernel/drivers/net/bonding/ directory on 
RHEL 5-based distributions.
Bonding Driver Parameters
 list the bonding driver parameters. Bonding driver options are supplied 
as parameters to the bonding module at load time. Though these parameters can 
be used as arguments in the modprobe command, it is recommended that they be 
specified in the /etc/modprobe.conf configuration file. If any of these 
parameters is not specified, the default value is used. 
NOTE:
Options with text values accept either the text name or, for backward 
compatibility, the option value. For example, mode= active-backup o 
and mode=1, set the same mode.

Parameter 
Name
Unit
Description
Default 
Value
Allowed Values
miimon
milliseconds Specifies the MII link monitor-
ing 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. The 
use_carrier parameter 
affects how the link state is 
determined.
0
arp_interval
milliseconds Specifies the ARP link moni-
toring frequency. ARP moni-
toring should not be used with 
miimon.
