摘要： A network device for implementing mirroring on packets. The network device includes a plurality of ports, each of which is at least one of an ingress port, an egress port and a mirror-to port. The network device also includes processing means for supporting a plurality of mirroring types. Each of the ingress port, egress port and mirror-to port includes at least one register for supporting the plurality of mirroring types. To support mirroring at each of the ingress port, egress port and mirror-to port predefined bits in the at least one register are set. When an incoming packet is received, the predefined bits are examined to determine which of the plurality of mirroring types to apply to the packet.

摘要： A network device that processes packets and includes at least one legacy component for performing basic processing on packets in the network device. The network device further includes at least one advanced component for performing advanced processing, which can not be performed by the legacy component, on packets in the network device. When an incoming packet to the legacy component requires advanced processing, the legacy component performs the basic processing and transmits the packet to a loop-back port on advanced component. Upon receiving the packet, basic processing is disabled on the advanced component and advanced processing is performed on the packet.

摘要： Methods and systems for processing packets in data network using multistage classification are disclosed. An example method for processing packets includes receiving a data packet at a first processing stage and examining the packet at the first processing stage to determine a first attribute of the packet. Based on the first attribute, a first classification is assigned to the packet. In the example method, the packet and the first classification are communicated from the first processing stage to a second processing stage and the packet is examined at the second processing stage to determine a second attribute of the packet. Based on the second attribute, a second classification is assigned to the packet. The example method further includes processing the packet based on the first classification and the second classification.

摘要： Methods and apparatus for communicating data traffic using switch fabric dispersion are disclosed. An example apparatus includes a first tier of switch elements; and a second tier of switch elements operationally coupled with the first tier of switch elements. In the example apparatus, the first tier of switch elements is configured to receive a data packet from a source. The first tier of switch elements is also configured to route the data packet to the second tier of switch elements in accordance with a dispersion function, where the dispersion function is based on a dispersion tag associated with the data packet. The first tier of switch elements is still further configured to transmit the data packet to a destination for the data packet after receiving it from the second tier of switch elements.
