Don't you have this anyway?
It's my understanding that channel bonding is an all or none
situation. You can't have a nonbonded workstation going to one
of the vlans, and then use that workstation to talk to the bonded
cluster nodes. You lose half a your packets coming back from the
bonded node, so those are retransmitted and half of those are lost
and so on, until eventually you will get all the packets but with
many many retranmissions.
