Explain VSphere Standard Switches

  1. A standard switch can bridge traffic internally between virtual machines in the same port group and link to external networks.
  2. Standard switches is used to combine the bandwidth of multiple network adapters and balance communications traffic among them.
  3. Standard switch is used to configure to handle physical NIC fail over.
  4. VSphere standard switch models a physical Ethernet switch. The default number of logical ports for a standard switch is 120.
  5. Can connect one network adapter of a virtual machine to each port. Each uplink adapter associated with a standard switch uses one port.
  6. Each logical port on the standard switch is a member of a single port group. Each standard switch can also have one or more port groups assigned to it.
  7. When two or more virtual machines are connected to the same standard switch, network traffic between them is routed locally. If an uplink adapter is attached to the standard switch, each virtual machine can access the external network that the adapter is connected to.
  8. Each port group is identified by a network label, which is unique to the current host. Network labels are used to make virtual machine configuration portable across hosts. All port groups in a datacenter that are physically connected to the same network are given the same label.
