6500 IOmem

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/15.1SY/config_guide/sup2T/qos_policy_based_queueing.html

Shaping can be done using MLS QoS and capabillities are dependent on the
modules. There are some benefits to applying shaping in this fashion. Port
buffers on 6500 switch (module dependent) are upwards of 200Mb depending on
module. It really depends on the hardware and comfort level with MLS QoS.
