More Information Needed (Score 1)

As a systems guy for a University, I know that announcements often come out several months before there is any implementation. My guess is that your school is going to follow the same path and have open meetings to discuss options. There is no way that a major school can shut off TCP ports 21-25 or 80 and 443. Those ports are the backbone of what many people consider the internet.

It is advisable, however, to shut off some TCP ports, especially those over 10000, and to limit the number of UDP ports offered at all.

Attend the meetings and find out what the central administration has in mind. Once you know where they are willing to draw the line, you can more easily negotiate opening more ports. Once the policy is written, however, it will be harder than hell to change.
