Re: Cat6507 system crash

You're getting what are known as MISTRAL errors.

(since this output is from a crash there is little documentation on it)

These are ASIC problems. (likey memory/buffer problems and commonly associated with an MSFC but could be an ASIC on a switching blade)(ASIC problems/failures are getting more common that I've seen over the last few years)

It looks like BLADE 5 is the main culprit in this case.

Try to remove BLADE 5, keep it out, and restart your switch and verify if any further errors occur.

If you have an MSFC, verify no other errors/problems are occuring.

(if not, prepare to replace the BLADE 5 with a new blade)

Use the following link for the Error Message Decoder to check other errors/messages:
