The topology diagrams of a vSphere Distributed Switch in the vSphere Web Client show the structure of virtual machine adapters, VMkernel adapters, and physical adapters in the switch.

You can examine the components, arranged in port groups, whose traffic is handled by the switch, and the connections between them. The diagram displays information about the physical adapter that connects the virtual adapters to the external network.

You can view the components that are running on the entire virtual distributed switch and on each host participating in it.

Central Topology Diagram

You can use the central topology diagram of the switch to locate and edit the settings for distributed port groups and uplink groups associated with multiple hosts. You can initiate migration of virtual machine adapters from a port group to a destination on the same or different switch. You can also reorganize the hosts and their networking on the switch by using the Add and Manage Hosts wizard.

Topology Diagram of a Host Proxy Switch

The topology diagram of a host proxy switch shows the adapters attached to the switch ports on the host. You can edit the settings of the VMkernel and physical adapters.

Diagram Filters

You can use diagram filters to limit the information displayed in topology diagrams. The default filter limits the topology diagram to display 32 port groups, 32 hosts, and 1024 virtual machines.

You can change the scope of the diagram by using no filters or by applying custom filters. By using a custom filter, you can view information only about a set of virtual machines, a set of port groups on certain hosts, or a port. You can create filters from the central topology diagram of the distributed switch.
