VI3 networking – Advanced Configuration and troubleshooting

This was a very technical session: speaker was Jean Lubatti that’s Product Support Engineer at Vmware.
He starts with some definition (vnic, vswitch and portgroup). The portgroup overview was expecially interesting (for me); in portgroups you can specify:
· VLANs configuration
· Teaming policies
· Layer 2 security policies
· Traffic shaping
Moreover portgroups are not VLANs: PG do not segment the vSwitches into separate broadcast domains unless they have different VLAN ID.
How can we implement VLANs? Two way:
· Virtual switches tagging (the easier way)
· External switches tagging (with virtual guest tagging in addition); this implies more work and more cabling
The native VLANs are fully supported by ESX (but pls, do not set any VLAN ID in vSwitches)
