I've set up a vCloud Director roughly following the appliance installation found in the vCloud "evaluation" guide. That guide assumes that VXLAN backed network pools will be used; apparently, I don't have the switch support for that scenario. Rather than sort that out, I'd like to just get my evaluation cloud up and running. With this in mind, I'm trying to figure out whether a Cloud Isolated Network will work for me.
I have:
1) a distributed switch
2) vlans and ip ranges available to me
Seems like this is all I need to be successful; I guess the vlan is optional but I'll need to specify one of my vlans, as I understand it. I'm a bit new to these networking topics, but if there are multipel vlans on the phsyical layer, I have to specify one for the network pool, correct?
My main question is about the MTU. Is the MTU increase only about performance? I understand that the tunneling information makes the total frame bigger than the standard 1500 bytes, and that cause fragmentation, but if this only performance, then my evaluation needs don't require that I make the MTU adjustment, at least as far as I can see.
Thoughts?
