Using the Labs

Always select the correct lab exercise for the lab being performed. Students or teams should schedule the correct lab exercise from the catalog. NETLAB+ will only show those labs for which the required pod type is available. A lab that works on different pod types may appear more than once if your system is so equipped. Instructors should select the correct lab from the Exercise tab during instructor-led lab reservations. This can be done as many times as needed during the reservation.
