The following notes are pretty out of date now. The linux kernel has native bonding support, which covers ALB and so on, as well as [802.3ad] and other forms of switch-dependant trunking. See LinuxEthernetBonding and [802.3ad] for more information |

As far as I know, Intel Etherexpress PRO100 and their brethren are the only adapters that support fault tolerance, load balancing, and other "teaming" features under Linux. |
|
|

|
|
|

These teaming features allow the following: |
|
|
7 |
|
|
|
8 |
AFT: Adapter Fault Tolerance. In this mode, one NIC in the "team" (designated the primary) is always active. If a fault occurs (cable, switch/hub port, or adapter), any one of the designated secondary cards in the team takes over. |
|
|

|
|
|
10 |
ALB: Adaptive Load Balancing. In this mode, the primary adapter transmits and receives, and the transmit mode is shared among all team member adapters. Fault tolerance is included as above. |
|
|

There are other modes available, such as ILA and FEC/GEC, but these rely on your switch supporting the features, and thus I will not document them here - excellent documentation is available at Intel.com if you do wish to implement these modes. |

The steps to implement this are fairly simple, once you actually find out that it can be done! |

NOTE: You will need to have the kernel source installed. |

1. Download the latest drivers and iANS software from intel. Search on your adapter, and Linux to find, as they move these frequently! |
|
|
19 |
|
|
|
20 |
2. Build the driver first, install and test. |
|
|
21 |
|
|
|
22 |
3. Untar the iANS software, cd to install_scripts/<Your Distro>/ and run ./INSTALL |
|
|
23 |
|
|
|
24 |
4. Follow the prompts! |
|
|

When complete, you should have a new interface with the name you gave it in step 4 (I used alb0), and should now be able to ping an IP on your LAN while removing cables with no loss in connectivity! :) |

Very cool for "[FiveNines]" type servers. |
