Hello all,
I am currently running Ubuntu 10.04, and it is working great. I have setup NIC Bonding, and it to went in without a hitch.
However, I noticed that I am having some "MAC Flapping" issues on my Cisco switch, and some quick research leads me to believe it is due to the Bonding mode I have my NIC's in.
I am running mode=6 or Balance-ALB. This is by far the best mode to run, as it requires no additional configuration on the switch side of the communication. However, after much research I notice that the NIC driver that is running on the host "must support changing the hardware address while the device is open". I am running this Ubuntu Server on a SuperMicro server that I have repurposed, and the NIC's that are running on this server are dual Intel 82546GB Gigabit controllers.
After trying to configure the bonding myself, and failing miserably, I found the following blog post that got me as far as I am now: http://blog.brightbox.co.uk/posts/ho...buntu-properly
As I said, the bond is up and running but I must be missing some other config. I am NOT a Linux guru, but I am not lost either. Bonding is a new thing on the Linux platform for me, I will admit that.
What I am actually trying to do is:
1. Find out what options (if any) I have left out of the configuration that will correct this issue.
2. Figure out how to confirm whether the drivers that are installed support the requirement of "changing the hardware address while the device is open".
3. Provide the completed solution to the community so others can successfully bond their Ubuntu Servers in this mode.
Thanks for your help!
