Parameter	Unit	Description	Default	Allowed Values
Name			Value
mode	Integer or	Specifies a bonding policy	balance-rr	 balance-rr or
	string		or 0	0—Round-robin policy
				transmits packets in
				sequential order from
				the first available slave
				through the last. This
				mode provides load
				balancing and fault tol-
				erance.
				 active-backup or
				1—Active-backup pol-
				icy specifies that only
				one slave in the bond is
				active. A different slave
				becomes active if and
				only if the active slave
				fails. The bond's MAC
				address is externally
				visible on only one port
				(network adapter) to
				avoid confusing the
				switch.
primary	String	A string (eth0, eth2, . . .) spec-	None	ethX
		ifying which slave is the pri-
		mary device. The specified
		device is always the active
		slave while it is available.
		Alternate devices are used
		only when the primary device
		is offline. This parameter is
		useful when one slave is pre-
		ferred over another for rea-
		sons such as higher
		throughput. The primary value
		is valid only for active-backup
		mode
