摘要： A network device for use in a networking system. The network device includes a packet processor adapted to receive control packets at a network port of the network device. The packet processor is also adapted to assign a CPU code to the control packets. The network device also includes a CPU in communication with the packet processor and a lookup table indexed by the CPU code and in communication with the packet processor. According to embodiments of the present invention, one or more entries in the lookup table define a rate limit in accordance with which packets characterized by the CPU code are delivered from the packet processor to the CPU.
