We have a 3-host VMWare vSphere v4.1 cluster that has a connection to an untagged network (let's call it 192.168.10.0
) using two physical adapters, vmnic1
and vmnic2
. Both are currently marked as "active". All three hosts have identical network configurations.
I need to migrate this network to a trunked connection, where 192.168.10.0
is in a VLAN instead of being untagged. My plan is to disable vmnic1
, plug it into the new trunk port then re-enable vmnic1
in a new virtual switch with VLANs configured.
What I'm wondering is:
- Can you unhook an (active) interface from a virtual switch without disrupting traffic?
- Can the network configuration be inconsistent across a cluster (not using HA) without causing global problems?
Bonus points:
- Through some kind of magic, is it be possible to connect the tagged interface to the same virtual switch as the current untagged interface, making for a smooth transition?
Edit: (from comment)
Followup question: If I reconfigure the existing virtual switch on one host to use tagged traffic, and then perform a vMotion to that host... Could that make for a smooth transition, right? (Ignoring temporary ARP issues)
