   Fedora allows administrators to bind multiple network interfaces together into a single, bonded, channel. Channel bonding enables two or more network interfaces to act as one, simultaneously increasing the bandwidth and providing redundancy.

+    The use of direct cable connections without network switches is not supported for bonding. The failover mechanisms described here will not work as expected without the presence of network switches.

+     The active-backup, balance-tlb and balance-alb modes do not require any specific configuration of the switch. Other bonding modes require configuring the switch to aggregate the links. For example, a Cisco switch requires EtherChannel for Modes 0, 2, and 3, but for Mode 4 LACP and EtherChannel are required. See the documentation supplied with your switch and see <ulink url="https://www.kernel.org/doc/Documentation/networking/bonding.txt">https://www.kernel.org/doc/Documentation/networking/bonding.txt</ulink><!--the <filename>bonding.txt</filename> file in the <package>kernel-doc</package> package (see <xref linkend="sec-Configure_Network_Bonding-docs-installable"/>)-->
