The network shaping (setting limit on the available bandwidth for outgoing traffic) is generally defined for each Container on the given Hardware Node on the Configure Shaping page in Parallels Infrastructure Manager. The Configure Traffic Shaping page (which you can access by clicking the Configure button on the Shaping subtab of the Network tab of the Container dashboard) allows you to define more precisely some of the shaping parameters for the given particular Container. To do this on Linux Nodes, you should first select the Configure the Container rate guarantees manually radio button in the Rate Guarantees Setup group of options.
Shaping is configured separately for each class. The default state of the Enable shaping for this class checkbox (selected or cleared) depends on what has been chosen on the Configure Shaping page. However, you can redefine if the shaping of this class should be turned on or off for this particular Container by setting this checkbox in the appropriate state.
The Total Rate field informs you of the bandwidth limit that is set for the corresponding class on the Hardware Node, which means that the summary outgoing traffic of all the Containers of this Hardware Node to the external addresses belonging to this class cannot exceed this value.
The Rate Guarantee value that you can set here will serve as the guaranteed rate for the given Container with this class of addresses. Note though that if the total of all the Rate Guarantee values of all the Containers exceeds the Bandwith value and all the Containers will demand traffic at the same moment, each Container will have to get less traffic than is guaranteed to it.
The Do not allow to exceed the rate guarantees checkbox, if selected, tells Infrastructure Manager to keep the Container from getting more bandwidth than is defined in its Rate Guarantee values, even if there is spare bandwidth on the Hardware Node for this class. Thus, you can efficiently impose bandwidth rate limits on any Container.
