Cisco Cisco IOS Software Release 12.2(27)SBC

The QoS: Percentage-Based Shaping feature allows you to configure traffic policing and traffic shaping 
on the basis of a percentage of bandwidth available on the interface. This feature also allows you to 
specify the committed (conform) burst (bc) size and the excess (peak) burst (be) size (used for 
configuring traffic shaping) in milliseconds (ms). Configuring traffic shaping in this manner enables you 
to use the same policy map for multiple interfaces with differing amounts of bandwidth.
