![]() VCenter Server system and the configuration is propagated to all hosts that are associated with the switch. You configure a vSphere distributed switch on the Even though a vSphere standard switch works much like a physical switch, it does not have some of the advanced functionality of a physical switch.Ī vSphere distributed switch acts as a single switch across all associated hosts in a data center to provide centralized provisioning, administration, and monitoring of virtual networks. This type of connection is similar to connecting physical switches together to create a larger network. A vSphere standard switch can be connected to physical switches by using physical Ethernet adapters, also referred to as uplink adapters, to join virtual networks with physical networks. It detects which virtual machines are logically connected to each of its virtual ports and uses that information to forward traffic to the correct virtual machines. It works much like a physical Ethernet switch. ![]() Multiple switches can be connected together to form larger networks. Switches are the core of a physical network. The switch learns which hosts are connected to which of its ports and uses that information to forward traffic to the correct physical machines. Each port can be configured to behave in certain ways depending on the needs of the machine connected to it. A switch has multiple ports, each of which can be connected to a single machine or another switch on the network. For more information, see Knowledge Base articleĪ physical ethernet switch manages network traffic between machines on the physical network. Such networks are not opaque, and are identified as NSX logical segments running on vDS 7.0. Note: With NSX-T 3.0, it is now possible to run NSX-T directly on vSphere Distributed Switch (vDS) version 7.0 or later. ® Manager or the VMware NSX API management tools. To manage an opaque network, use the management tools associated with the opaque network, such as VMware NSX You can choose an opaque network as the backing for a VM network adapter. VCenter Server as opaque networks of the type nsx.LogicalSwitch. For example, logical networks that are created and managed by VMware NSX Virtual machines can be connected to the virtual networks that you create when you add a network.Īn opaque network is a network created and managed by a separate entity outside of vSphere. VMwareĪ network of virtual machines running on a physical machine that are connected logically to each other so that they can send data to and receive data from each other. Physical NetworkĪ network of physical machines that are connected so that they can send data to and receive data from each other. If you are new to vSphere, it is helpful to review these concepts. A few concepts are essential for a thorough understanding of virtual networking.
