Comment 2 for bug 1041070

Thanks for taking the time to report this bug in Ubuntu.

As you are configuring with "bond-mode 802.3ad" this will also require configuration on the switch your server is connected to - please can you confirm that this has been done? Configuration of the switch will depend on vendor so unfortunately I can't give you an easy way to check.

Marking 'Incomplete' for the time being; please set back to 'New' if you believe the switch is correctly configured.
