Under Linux, the Kernel allows you to bond 2 or more network cards. Bonding network cards allows you to double the speed in both directions and allows you to balance the network ~~mode~~ between them. It can also make connection redundancy in case a network link fails. In this article, you will be shown how to bond the cards using the YaST Network Settings utility.

Under Linux, the Kernel allows you to bond 2 or more network cards. Bonding network cards allows you to double the speed in both directions and allows you to balance the network load between them.

== What you need to know ==

* You will need more than one network card.

* This will only work under the traditional ifup method of configuration and doesn't work under NetworkManager or wicked network management.

* This will only work under the traditional ifup or wickedd method of configuration and doesn't work under NetworkManager or wicked network management.

* You will need to know the interface names of the cards.

* You should decide what kind of load-balancing you want to use. You can view available modes [[#Choosing_a_bonding_mode|here]].

== Bonding via YaST ==

# Goto Launch menu > ~~Computer~~ > YaST ~~Control Center~~

# Goto Launch menu > System > YaST

# Select 'Network Settings' under the 'Network devices' heading. This will display the network interfaces on your system and how they are configured.

# Select the 'Global Options' tab.

Line 18:

#* Click on a card and press the 'Edit' button. This will open on the 'Address' tab.

#* You will need to change the 'Dynamic Address' or 'Statically assigned IP Address' radio button to 'No IP Address (for Bonding Devices)'. Make sure the 'Use iBFT values' tick box is not ticked.

#* Click OK. This will return you to the 'Overview' tab. Next to the network card you just ~~editied~~, under the 'IP Address' list heading, it should now be listed as 'NONE'.

#* Click OK. This will return you to the 'Overview' tab. Next to the network card you just edited, under the 'IP Address' list heading, it should now be listed as 'NONE'.

#* Repeat these steps for any other cards you will be including in the bond.

# Double check all cards you will be including all say 'NONE' in the 'IP Address' field.

Line 30:

#*At this point you can check that you have network connectivity by opening a web browser and trying to open a web page.

# Open Konsole from the Launch menu.

# Now type <code>ifconfig</code>. This will output your network configuration. This is an example:

# Now type <code>sudo ifconfig</code>. This will output your network configuration. This is an example:

bond0 Link encap:Ethernet HWaddr <MAC Address>
