Easy enough! There are 2 ways to approach this: If you have Switches which support Cisco's EtherChannel spec, then there's a standard kernel driver called bonding.o. Here's the comments form the bonding.c source itself: /* * originally based on the dummy device. * * Copyright 1999, Thomas Davis, tadavis@lbl.gov. * Licensed under the GPL. Based on dummy.c, and eql.c devices. * * bonding.c: an Ethernet Bonding driver * * This is useful to talk to a Cisco EtherChannel compatible equipment: * Cisco 5500 * Sun Trunking (Solaris) * Alteon AceDirector Trunks * Linux Bonding * and probably many L2 switches ... * You can look at the rest of the comments to look at usage. Here's a page I found with performance and cards that have been used with the driver. http://www.sfu.ca/acs/cluster/nic-test.html Optionally, there's another driver that Intel wrote specifically for their cards. The driver is called iANS, and can be found on Intel's site. They provide support both for EhterChannel bonding and simple failover scenarios. Hope this helps! Donavan Pantke
