Thanks. I hadn't see that page before and it was helpful.
I managed to get my Ubuntu 12.04 LTS server running Mode 4 (server)/LACP (switch)
Is there a way to get figures for the maximum throughput of the server/switch? I've been using iperf which gives variable results, presumably because of the dynamic nature of Mode 4.
However, on a Debian Stable server I can't get it to run in the same configuration - only Mode 0 (server)/Static LAG (switch)
I don't know if this is because the version of the Ethernet Channel Bonding Driver;
Ubuntu 12.04 LTS - v3.7.1 (April 27, 2011)
Debian Stable - v3.5.0 (November 4, 2008)
The two servers are different, so it may be down to the builtin ethernet card chipsets. Is there a way to determine which modes are supported by the NIC card?
Your help is very much appreciated.
