After we upgraded to 2.1(3c), the issue described in CSCuh61202 still occurs. We have logged a new bug: https://tools.cisco.com/bugsearch/bug/CSCuq40256Has anyone else experienced the same?
Not according to this: https://tools.cisco.com/bugsearch/bug/CSCus61659 It says you need to be at least on 2.2(3f) to avoid this PFC issue altogether. It truly feels like Cisco just cannot squash this bug (or a family of bugs).
Very interesting. It basically seems that they half-fixed the bug. The frequency of the occurrences has reduced, but it occurs nonetheless. We're pushing Cisco for an expedited release of the fix.
