RedHat 4

1. Find current bonding mode:

# cat /proc/net/bonding/bond0
...
Bonding mode: round-robin

2. Down all bonding information and change the bonding mode:

# ifdown bond0
NOTE: please down other bonding interfaces if you have

# rmmod bonding

Edit /etc/modprobe.conf to change the bonding options (the line should look like ):options bonding mode=0 miimon=100

This can be changed to: options bonding mode=1 miimon=100

3. Up the bond0 (and other bonding interface) again. The bonding module will be reloaded automatically:

# ifup bond0

4. Check if the bonding mode has been changed:

# cat /proc/net/bonding/bond0
