6500 IOmem

Hi Guys. I've been studying QoS and am confused on something. Does the 6500
use an IOMem in DRAM for packet buffers? I've been trying to figure out if
the 6500 can do any type of traffic shaping on Ethernet cards (not TDM) and it
looks like a big NO. Then I started investigating to find that smaller
platforms do the shaping in DRAM using IOMem. Now when I issue the command
"show region" on my sup720 I do see IOMem is there but what is it used for? I
know that packets are switched/routed in the ASICs on the PFC and DFC if
available but wouldn't process switched packets hit IOMem?
 
If you have
read this far I owe you a big Thank You :)
