CAT 4500 error 4900M - %C4K_SWITCHINGENGINEMAN-4-VFEICINTERRUPTICCERR:


We have recently upgraded a number of these model switches to cat4500e-ipbasek9-mz.122-54.SG1.bin ... about 12 weeks ago. Of the 6 that we upgraded, one has had the following triggered on it.

What concerns me is that there was nothing in the logs preceding this alarm .. documentation reflects that it's an informative message and no action is required ... but why would it keep repeating on a 10 minute cycle since it was first triggered?

What you have seen are the correctable parity errors. To learn more about Parity Errors please click here for CCO documentations. Please click here for documentation on troubleshooting line cards.

In general that is usually transient if seen once - or HW problem in case of mulitple occurrencies. So if that is still scrolling - please consider the replacement of Supervisor (RMA). The scrolling message is confusing and possibly should be addressed in SW. However the root cause for it is HW parity error. The reload should stop this error - on re-occurrence replace it.

In regards to scrolling message It can be both - DE actually need to look into the code. SO if that parity error stays there as not correctable and switch is doing regular routine and finds that again and again - thus the continious logs. I guess nothing can be changed in the way it handles that.
