NPE-G2 Overview
Bandwidth Requirements
The Gigabit Ethernet ports on the NPE-G2 do not use bandwidth points, nor does the Fast Ethernet
management port. When used with any I/O controller, the Ethernet ports, Fast Ethernet ports, or Gigabit
Ethernet ports on the I/O controller also do not use bandwidth points.
