I just went through the Networkers slides for the catalyst 3750 and 3750E. I'm looking for information on the amount of packet memory that is available to help with speed conversion when traffic enters the switch on a 10 Gig port and exits on a lower speed port. I can find a lot of information on the percentage allocations but nothing that tells me how much memory there is. It looks like each port ASIC manages its own output buffers and that however much there is gets shared amoung all the ports common to each port ASIC. But, how do I find out how much there is? It would also be good to know if it is managed as particles -- each packet gets what it needs -- or if it is preallocated into MTU sized chunks.
This question is much easier for the Catalyst 6500 than for the shared memory access switches.
Excuse me for bringing up an old post but I too am looking for the same information that you mention in your posts. I was wondering if you ever did find a suitable answer to your questions as I am looking to do the same with my 3750's? All of the documentation I can find either relates to routing or to higher end switches. There is very little with regards to buffers on 3750 type switches.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
