  1. Physical Hardware > Physical NIC
  2. Virtual Hardware
    • Virtual NIC
      • Virtualization
        • VMXNET
        • VMXNET2
        • VMXNET3
      • Emulation
        • e1000
        • e1000e
    • Virtual Switch
      • L2 Switch(MAC needed)
      • Not Based on Hardware
      • CPU Dependence 
      • Doesn't Learn MAC addr why? creation by hypervisor
      • How to make MAC? OUI + Number
      • vSwtiches do not require STP because they are not connected
      • VLAN and Trunk Support
        • if using VLAN with esxi supports 802.1q therefore physical nic supported 802.1q
      • Addtional Feature : Security, QoS, FO, LB
      • Standard Virtual Switch(SVS)
      • Distribute Virtual Swtich(DVS)
      • port group
        • vm port group = vmnic
        • vm kernel port group =  hypervisor ( for externel connect) = vmk
          • vm kernel port is only one connect therefore called vm kernel port
