Hey everyone. Just wanted to let you know that if you ever wanted to calculate queue and threshold depth of Catalyst 2960/3560/3750, now there is an easier way. By reverse engineering memory blocks a bit, I was able to figure out the memory structure and what those frustrating percentages mean. With this calculator you can enter byte values for the queues and it will generate all the needed commands, check sanity and calculate some interesting ratios and statistics. You can also check "how many" packets of certain size will fit there, due to memory structure overhead (256-Byte cells). Anyway, check it out, and hopefully it'll enhance your understanding of Catalyst QoS in the Sasquatch family.
P.S.: All Sasquatch family members have same architectural approach, so it procedure is the same on 2960 and 3750G alike. 3..0E, 2960S and 3..0X models types have a bit different method of calculation.
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!
