This is complicated with the bond+trunk. Basically what I need to happen is

have a very limited maintenance window to make this work, I would appreciate
some feedback. One way I thought about doing it was to create a bond0:0
interface and add the SAN ip stuff to it. Should this work?
With your setup? No. Since you already carve-out bond0.20, all traffic
on vlan20 will go there.

Vlan20 is the SAN vlan and it has on it. In debian I know how to
accomplish this since you use the vmbrX interface and give it an IP. However
I am not 100% sure how to do this in centos. I appreciate any help on this.
Just put the IP on ifcfg-br20. Add the usual


I noticed that you put ip address on bond0. Is that on native vlan? If
not, you should also move it to ifcfg-br*.

Thanks for that. That makes sense. Although I won't need a gateway since it does not need to leave that vlan. Also the management IP is on the default vlan of 1. But I can move it to the br* interface if it would help anything.
