Bit hard by same bug. What version of code are you running on the 6513 8.1(2) fixes the bug on the 6x48 line cards. What happens is that packets of 64 bytes or less are silently dropped. Replacing linecards will not help unless there is another bug of which I am not aware. With a little digging I can dredge up the relevant DDTS. Scott C. McGrath On Sat, 13 Mar 2004, joe wrote:

Well barring that, I've seen simuliar issues, maybe not the exact same timings but. I've noticed a couple of things while working with a roll out of Active-Directory and a recent upgrade to I.E 6.0 for the user base. Since there were several thousand users involved some of the issues were simply bad configs/drivers/etc. However one of the stats I have noticed is that in certain situations where a system is connected to a Cisco 3548, and the client is running in an Auto detect (AD/AN) mode that things are horendiously slow during boot up, and at various times seem to hang unexplainably. It seemed corrected by setting the client to 100/Full, but not in all cases. Lots of HTTP complaints still remain about accessing webpages etc. but never consistant. This of course is a pretty fresh problem and is still in my queue for research to start this Monday. As well, we've found that there was an odd bug with Cisco's 6513s and their 48 port 10/100/1000 line cards. This was using the latest IOS/CAT software at the time. Again not sure if its a documented problem but, several users were unable to Telnet or FTP to systems that teminated to the 6513, oddly we were able to icmp echo and pass HTTP. After sometime and 2 TACs I found that there was a bug regarding these items and real small packets (I Think less than 64bits??) being passed thru the 6513 and got an RMA for new Line cards. Again, perhaps nothing to do with your situation. Since the Nix systems and non-Doze seem not to have an issue, perhaps you can enlighten me with further Sniffs/Captures of these events directly? As soon as I get some more data/Captures on my end from the problems I'm seeing I can forward those apon request so as to keep S/N ratio down on Nanog (:
