Why each option
To encapsulate VXLAN traffic from a connected VMkernel interface on a Cisco Nexus 1000V Series Switch, the 'capability l3control' command must be run on the port profile.
The command 'encapsulation vxlan' is used for defining the VXLAN encapsulation type, but 'capability l3control' is the required command on the port profile itself to enable VXLAN for VMkernel interfaces.
On the Cisco Nexus 1000V, the 'capability l3control' command is applied to a port profile to enable it for Layer 3 control plane functions, which is necessary for the VXLAN functionality to encapsulate VMkernel traffic.
The command 'capability vxlan' is not the correct command to enable VXLAN encapsulation for a port profile on the Cisco Nexus 1000V.
The command 'system vlan 100' is used to define a system VLAN, not to enable VXLAN encapsulation on a port profile.
