Re: 6500 IOmem

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?

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 :)
