What is the purpose of PubY on eth1?

I'm assuming "will connectivity" should have been "will lose connectivity",
which is what I feared. I'm glad I asked!

Excellent, I'll try that. Thanks!

My next question is for future planning. There is a second interface
(eth1) with a separate physical network which only contains the engine,
nodes and the nfs server.

Can the mgmt network be easily moved to eth1? Then the pubX would be
non-vlan on eth0, and mgmt + privY would be on eth1. If all the eth1
interfaces are connected to a dedicated/isolated switch, does that switch
need to explicitly support vlans, or does it matter?
