Buffer sizes on various switches (cisco and others)

Spotted on cisco-nsp, seems like a handy reference of otherwise undocumented info:

This is probably covered 99% of the time in data sheets - at least on Arista gear it is.  Buffering is an important topic to know -  particularly in the DC - and one that I surprisingly remember hearing nothing about in my CCNP studies.  I embarrassingly didn't know anything about the subject really until I started working where I do now.

Nice to see a document that has a lot of it all in one place. Saved that link.

I must be honest, I didnt know anything about Port Buffer before NFS.

The only I knew, If it can be considered something to know, is "Never do port-channels inside same ASIC" so I usually do port-channels using port of differents ASICs.

Its a shame, I know

thats a great article which has helped me heaps in the past - the only thing missing is a proper description of all the different kinds of buffers, esp. the more esoteric ones


Just to throw more info into the pile - good old breakdown of the ASIC breakdown on the 3850s.
