Alberto,
Are you spanning multiple ports through which each packets would traverse?
You may find this is a feature, not a bug. :-) It happens to me all the
time when I span multiple ports on Cisco 6509's, I just need to be more
selective about where I capture my data. Other sniffers may automatically
remove these packets w/o telling you.
