A “bandwidth management class” defines a bandwidth limit that virtual servers can apply to data sent to clients. For example, if several large download connections were assigned a shared limit bandwidth class of 250Kbits, these connections could not consume more than this limit.

You can apply a bandwidth management class to a virtual server by clicking the **Classes** link on the appropriate **Virtual Servers > Edit** page. In the Bandwidth Management section, select a class from the list and click **Update**. This will have the effect of limiting all the traffic the virtual server manages to the defined value in the class, according to the limit sharing type specified (per-connection, per-machine, or cluster-wide).

Bandwidth Management is covered in detail in [Bandwidth Management](docId\:amcCuT4eS65c2JcvL3WNO).
