I am suggesting that we need a Feature INTERACTION Matrix. That is, something which shows which features Do NOT work with other features. Most docs list the features available with some IOS release or sometimes with reference to certain hardware cards. What is not listed is the restriction which comes about when turning on features. e.g. If I use Port Security on a Cat65, which features can I not then enable? If I enable security to the phones in UC7, which features then do I lose?
This info is Usually somewhere in the Restrictions section of the Feature Guide. But tends to be lost when the feature is no longer "new".
In summary, my wishlist item for tech doc is to have some kind of a tool / table / matrix which will allow me to pick some features which I want to configure and for it to tell me if they are supposed to all work together. Additionally, what other features do I lose if I turn these On.
