Anyone ever experience "degraded performance" with a C4K platform. CPU, Mem, Port Util/errors are all unaffected. But, throughput is slow, and seems to clear up after reset. I have seen degraded performance but that could always be traced to errors at some level. Just looking for some indication of history with this platform....4006 specifically.

Usual stuff, IP and Multicast mostly, No IPX. It has been reported that the slowness was corrected after a reset, but prior to the reset we were not seeing any indications from the switch that it was struggling. Just looking for either similar occurances from others or perhaps some tips on watching the switch for performance that may not be obvious indicators. CPU, Mem, errors and Port Util are the big 4 we track.....any other items that may be indicative of problems???????
Do a "show test switch-memory detail" and see if all your asics are operating correctly . I believe that version of OS supports this , what it is the supervisor runs a continuous test on the asics , if it sees a problem with the buffers it should reset the switch and take the bad buffers off so they cannot be used . If this is your problem you should see a message in the logging buffer . If it has rebooted and taken bad buffer space out it may be running low on buffer space thus slowing traffic down . In almost all cases the supervisor will need to replaced , this is bug CSCec78085 .
