SUSE / Setting Up Bonding Devices

1. Run YaST > Network Devices > Network Settings.
2. Use Add and change the Device Type to Bond. Proceed with Next.
   
   
3. Select how to assign the IP address to the bonding device. Three methods are at your disposal:
   • No IP Address
   • Dynamic Address (with DHCP or Zeroconf)
   • Statically assigned IP Address
   Use the method that is appropriate for your environment.
4. In the Bond Slaves tab, select the Ethernet devices that should be included into the bond by activating the related check box.
5. Edit the Bond Driver Options. The modes that are available for configuration are the following:
   • balance-rr
   • active-backup
   • balance-xor
   • broadcast
   • 802.3ad
   • balance-tlb
   • balance-alb
6. Make sure that the parameter miimon=100 is added to the Bond Driver Options. Without this parameter, the data integrity is not checked regularly.
7. Click Next and leave YaST with OK to create the device.
