[Dave Click]

338.10(B)(4)(b) says to support in accordance with 334.30:

334.30 Securing and Supporting.
Nonmetallic-sheathed cable shall be supported and secured by staples, 
cable ties, straps, hangers, or similar fittings designed and installed 
so as not to damage the cable, at intervals not exceeding 1.4 m (4.5 ft) 
and within 300 mm (12 in.) of every outlet box, junction box, cabinet, 
or fitting. Flat cables shall not be stapled on edge.
Sections of cable protected from physical damage by raceway shall not be 
required to be secured within the raceway.
