[ovirt-users] management interface

Thu Aug 4 20:50:06 UTC 2016

Edward,

I am sorry that the diagram was not clear enough.

There is two bonds (4 phisical nic's, each pair is LACP). One for mgmt
traffic only and one to carry untag and tag traffic.
But I do understand your point.
I will try to separate this and have everything on its own access port.

To move my current ovirtmgmt interface to a new one all I have to do is
create one and assign it and remove the old one correct?
Thanks again!

Regards,
