Degree all the way.
It seems like you are talking about two different things, possibly three. The Cisco program is usually a certificate program that will prepare you for a Cisco CCNA, CCNP, CCIE. Computer Information Systems is either an Associate or Bachelors Degree that gives you experience in a wide range of disciplines: Windows, UNIX, networking, some programming, etc.
On face value, I would say go for the Bachelors degree, and if you some type of computer experience (i.e., building your own computer) or at least a really big desire in computers, I would say try to get a job at your local computer store. Try the bigger chains, like Best Buy, CompUSA, or whatever is in your area. You want to gain experience, which can be more helpful sometimes than paper that says you completed a program. Ideally, you want the degree, certification, and experience.
I wouldn’t just go for the Cisco certificate unless you have some experience in the field, and you want to add to arsenal by having a Cisco cert. Cisco is very good to have, but you want to be well rounded, and you won’t need to renew your college degree every few years.
