In your viewport -- (Persp in this case)

View -> Camera Attribute Editor

Near Clip Plane -- how close to the camera do you want Maya to Draw? (Maya Units, mine's set to 0.1)

Far Clip Plane (your problem) -- how far from the Camera do you want Maya to Draw? (Maya Units, mine's set to 1000)

You can make it as large or as small as possible... but your performance will drop.
