Re: 6500 IOmem

Thanks Joseph. I'll have to look up microflow policers. I've not heard of
that one. I was looking to do shaping to be a little nicer to the traffic
rather then policing. This is an enterprise branch network so we don't want
to drop traffic if we don't have to. Delayed is preferred :)

The
policing the 6500 can do is kinda like shaping to the flow.

The 6509's
microflow policers are very valuable also. A poor man's Bluecoat wan shaper
imho.

Those Bluecoats are like 250k though :(

If you're trying to choke down
customers to their cir, you can do it with the 6509

Both. Was studying QoS but we are implementing a new branch
network and are going with ASR1002 series routers for the traffic shaping on
Ethernet interfaces. Was trying to get to the bottom of why a 6500 would not
work and this seems to be it.

No hardware QOS only

Are you studying or configuring a
production network?

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 :)
