Greetings, I was looking to get some feedback as to what people are using in production on 75XX routers on standard line cards (HIP for example) for switching paths. I read one time on Cisco's site that on a 7500 non-vip router, you can see up to 150k PPS using plain fast-switching, and up to 275k by using optimum. Could someone be kind enough to elaborate on the differences between fast/optimum switching other than the addition of 'optimum' on the command line ?? I dont remeber seeing too much detailed info on the differences of these earlier switching paths on CCO. Feel free to reply directly via email/off-list. Thanks in advance. -------------------------------------------------- Brandon Applegate, CCNA : Network Administrator http://www.one.net : brandon@one.net --------------------------------------------------
