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 http://www.kernel.org/doc/Documentation/networking/bonding.txt.

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

Table 6-4list 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.

Table 6-4. Linux Bonding Driver Parameters

Parameter	Unit	Description		Default	Allowed Values
Name				Value
miimon	milliseconds	Specifies the MII link monitor-			0
		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.
arp_interval	milliseconds	Specifies the ARP link moni-	0		32767
		toring frequency. ARP moni-
		toring should not be used with
		miimon.
