Re: 6500 IOmem

Branch connectivity is over Ethernet and not TDM so flexwan won't work.

Dave,

The 6500 does hardware qos on all switchports. If you
want to do traffic shaping you need a flexwan card or a sip/spa style card.

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 :)
