i think they're two different processes. the PPS is the direct amount of calculations it can do and the GBPS would be the bandwidth. so if you had 18Mpps and 24GBPS, and you tried to switch 18M packets all of MTU (1500) it would be 18000000 * 1500 = 27000000000 or 27GBPS so you exceed the bandwidth that the sup card could handle, so with the higher bandwidth the SUP can handle the same amount of packets but of larger sizes. this is how i see it and i hope it's correct. if not please let me know. steve

[7:54833] What does this mean. I was looking at table 21-112. The difference between supervisor engine I and supervisor engine II is that the I has 24 Gbps switching engine and the II has three 24 Gbps. Yet the pps remains the same(18Mpps). Is there a direct correlation between the switching fabric and the switching throughput. If there is reading online that would be great. Here is the link I was referring to. http://www.cisco.com/univercd/cc/td/doc/pcat/ca4000.htm Ryan Newell Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=54863&t=54863 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
