Are you all referring to "mls ip cef rate-limit"? If so, what do you think would be a good value to use on a Sup 720? We'd like to set it so that the CPU isn't overloaded so much that routing protocols drop and we don't lose our SSH sessions. That way we can monitor it and watch to see when the CPU drops back down to normal.
