Guys,

after reading nearly every article on bonding I felt compelled to add this to the mix.  On RH Enterprise version 4(update 5) i could not get mode 1 bonding working.  it kept using load balancing round robin and as I had both nics connected to different switches in a redundent network topology it was causing duplicate packets which was causing delays when opening web pages on the apaches.

anyway below is the recommended config and the actual working config I hope it saves someone time in the future......

alias bond0 bonding

install bond0 /sbin/modprobe bonding -o bond0 mode=1 miimon=100

alias eth0 bnx2

alias eth1 bnx2

alias eth2 e1000

alias scsi_hostadapter megaraid_sas

alias scsi_hostadapter1 ata_piix

alias usb-controller ehci-hcd

alias usb-controller1 uhci-hcd

install bond0 /sbin/modprobe bonding -o bond0 mode=1 miimon=100 primary=eth0

alias eth0 bnx2

alias eth1 bnx2

alias eth2 e1000

alias scsi_hostadapter megaraid_sas

alias scsi_hostadapter1 ata_piix

alias usb-controller ehci-hcd

alias usb-controller1 uhci-hcd
