Physical switch implementation for vCNI backed networks

Hi,

Let's say one vCNI network pool is created on a vDS with optional VLAN ID, MTU set to 1524.

For each Organization, create one Routed and one Internal network based on the vCNI network pool, the respectiive networks are 192.168.0.0/24 and 192.168.1.0/24 by default, and respective vSE VM are also created.

The Uplink of vDS connect to physical switch ports, what configuration is reuqired on the physical switch? I'm not a network guy, can only assume to setup VLAN ID, two networks, and MTU for required ports? The Traffic Flow diagrams in Duncan't blog at http://www.yellow-bricks.com/2010/09/15/vcd-networking-part-3-use-case/ are very helpful.

It looks like MAC-in-MAC encapsulation is used to isolated vCNI-backed networks, since they share the same IP ranges, is there an easy to understand turtorials on MAC-in-MAC encapsulation?

Thanks,

William

Sorry I don't know how to read pcap (yet).

Just checked, the vDS still has max MTU set to 1500, don't know how to check MTU of NIC/Uplink.

Don't we need to increase MTU to 1524 for vDS and Uplinks?
