No. Not "now for the questions." If you want to ask whether we are using
a feature, you have to tell us the name of the feature. You will not get
quality
answers by asking us whether we are using something without telling us
what it is. You should go to your network engineers and get their
assistance
to help you form up your questions. I have configured cisco WiFi and
switches.
I don't have the faintest idea what you're talking about. Often when cisco
builds a custom feature to solve a specific customer problem they will
write an application note to explain how to use the new feature. A link to
that paper would be a good thing.
