How to set up bonding with YaST2

Network bonding needs to be configured with YaST2.

1. Start YaST2:
   yast2 lan
2. For the network interfaces intended to be used as bond slaves, ensure they are configured with the following parameters:

• Traditional method with ifup
• Click "Edit" to get to the "Addresses" section and chose: "No IP address (for bonding devices)" or "No Link and IP Setup (Bonding Slaves)".
  
• For SLES 11 SP1 and prior, under the "General" section choose Device activation "Never".  SLES11 SP1 can also be set to "On Hotplug".  With SLES 11 SP2 and later, Device activation should be set to "On Hotplug"
• Click "Next" to exit the interface configuration screen

3. Click "Add" => Device type "Bond network" => "Next".
4. Under "Address" choose "Automatic Address Setup" for DHCP or "Static Address Setup" for static IP address configuration
5. Now the previously configured network will be marked as ready for "Bond Slaves". Mark here all the network cards which should be bonded.
6. Choose "Bond Driver Options" and configure the preferred bonding method
7. Finish the setup by clicking "Next"

If the bonding configuration is correct, the command /sbin/ifconfig should look similar to this:
