A logical switch reproduces Layer 2 and Layer 3 switching functionality (unicast, multicast, broadcast) in a virtual environment completely decoupled from underlying hardware.


Log in to the vSphere Web Client.


Click Networking & Security and then click Logical Switches.


Click the New Logical Switch icon.


Type a name and description for the logical switch.


Select the transport zone in which you want to create the virtualized network. The Scope Details panel displays the clusters that are part of the selected transport zone and the services available to be deployed on the scope.


By default, the logical switch inherits the control plane mode from the transport zone. You can change it to one of the other available modes:

Unicast: The control plane is handled by an NSX controller. All traffic replication is handled locally by the hypervisor. No multicast IP addresses or special network configuration is required.

Hybrid: The optimized unicast mode. Offloads local traffic replication to physical network. This requires IGMP snooping on the first-hop switch, but does not require PIM. First-hop switch handles traffic replication for the subnet.

Multicast: Multicast IP addresses on physical network is used for the control plane. This mode is recommended only when you are upgrading from older VXLAN deployments. Requires PIM/IGMP on physical network.


Click OK.
