Table 185. Traffic Type Utilization

Description	Illustrates how different types of data traffic are represented in the overall network traffic managed by the selected switch. The current percentages of different type of network traffic appear in the table, while the chart displays the values captured over the selected time period.
Data displayed	• FT. The percentage of network traffic resulting from VMware Fault Tolerance (FT) operations, processed by the selected switch.
	• HBR. The percentage of network traffic resulting from host-based replication (HBR) operations, processed by the selected switch.
	• iScsi. The percentage of iSCSI (Internet Small Computer System Interface) network traffic processed by the selected switch.
	• NFS. The percentage of network traffic resulting from Network File System (NFS) operations, processed by the selected switch.
	• vMotion. The percentage of network traffic resulting from VMware vMotion operations, processed by the selected switch.
	• VM. The percentage of network traffic between virtual machines managed by the selected switch.
Where to go next	Drill down on:
	• Traffic Type Utilization chart. Displays the Traffic Type Utilization dialog box.

Summary - Distributed Virtual Switch view

The Summary - Distributed Virtual Switch view illustrates the overall network utilization and the levels of overall network packet loss for a selected distributed virtual switch.

NetFlow is a network protocol that enables distributed virtual switches to collect IP traffic information as the data flow enters or exits an interface. These statistics can later be exported and serve as a basis for potential traffic analysis. You can enable this feature on desired distributed virtual switches.

The NetFlow data can be collected from your monitored environment only if your VMware user account includes the following privileges:

For additional information about these privileges, see your VMware documentation.

Table 186. Product Information

Description	Shows the name of the selected switch along with some basic configuration information.
Data displayed	• Available Ports. The number of switch ports that are available for use out of the total number of ports.
	• Load Balancing. One or more load balancing policies, indicating how the switch routes network traffic in case of an adapter failure. For example, an uplink may choose a route based on the originating virtual port, IP hash, source MAC hash, physical NIC load, or use a specified fail over order. For more information about these policies, see your VMware documentation.
	• Network I/O Control. Indicates if the selected switch can use network resource pools to prioritize network traffic.
	• Traffic Shaping. Indicates if the traffic shaping policy is enabled or disabled on the selected switch. A traffic shaping policy can restrict the network bandwidth to a port or if a port is configured to temporarily allow transmission of data at higher than normal speeds. For more information about these policies, see your VMware documentation.
	• Type. The type of the switch: VMware Distributed Virtual Switch.
	• Version. The version number of the distributed switch component in your virtual environment.
Where to go next	Drill down on:
	• Product Information. Displays a dwell, providing additional configuration information about the selected distributed virtual switch. To find out more about the network I/O traffic passing through the selected switch, in the dwell, on the right of Network I/O Control, click Enabled. To find out more about the traffic shaping policy, on the right of Traffic Shaping, click Enabled.

Standard vSwitch Topology and Distributed vSwitch Topology views

The Standard vSwitch Topology View and Distributed vSwitch Topology View visualize the relationships between the objects in your environment through an interactive dependency map. The map illustrates how different components relate to each other, and the levels of the available resources available to them.

Topology views are also available for other components on the VMware Environment dashboard. For complete information about topology views, see Topology views .
