Traffic shaping is used to limit the amount of bandwidth that's available to virtual switch ports. NIOC is used to apply limits and to guarantee traffic to different virtual network service types.
Traffic shaping can be configured on vSwitches, vDSwitch uplinks, VMkernel interfaces, and PortGroups to restrict the network bandwidth available to the network ports on the virtual switch. Traffic shaping is applied at all times, regardless of the amount of network capacity available. This means that if traffic shaping is enabled and configured on a virtual switch or PortGroup to limit the peak bandwidth to 1,048,576 Kbps (1 Gbps), only 1,048,576 Kbps of bandwidth will be used, even if more bandwidth is available.
The following bandwidth ...
