摘要： A network device includes at least one source physical port configured to be coupled to a network, a plurality of egress ports, and a packet processor. The packet processor includes a processing stage configured to implement a logical port assignment mechanism to assign source logical port information to a data packet received via one of the at least one source physical port, wherein the source logical port information is based on characteristics of the data packet, wherein the source logical port information corresponds to a logical entity that is different from any source physical port, and a forwarding engine to determine one or more egress ports for forwarding the data packet based on at least the assigned source logical port information.

摘要： A network switch includes a memory to store associations between at least one flooding domain and a plurality of network interfaces. A classifier assigns a processor code to selected packets received at one or more of the network interfaces. The processor code includes a flag indicating if a packet is to be processed by a processor. A transfer circuit transfers packets among the network interfaces based on the associations and transfers the selected packets to the processor based on the processor code independently of transfer of packets to at least one flooding domain.

摘要： Devices, systems, methods, and other embodiments associated with cascaded memory tables for searching are described. In one embodiment, an integrated chip is implemented with two or more address tables. The two or more address tables are implemented with separate memory tables to store addresses. The two or more address tables are comprised of a first address table and a second address table. Connection lines connect the first address table and the second address table to create a cascaded address table. Search logic initiates a search of the first address table for an address. If the address is not found, the search logic initiates a search of the second address table through the connection lines.

摘要： A packet is received from a network via an ingress port, wherein the packet includes at least first and second headers. A first set of one or more egress ports via which the packet is to be forwarded is determined based on one of the first header or the second header, and the packet is forwarded to the first set of one or more egress ports. At least a subset of the packet is forwarded to an upstream location in a packet processing pipeline, and a second set of one or more egress ports via which the at least a portion of the packet is to be forwarded is determined in response to forwarding the at least the subset of the packet to the upstream location in the packet processing pipeline and based on at least one of the first header or the second header. The at least the portion of the packet is forwarded to the second set of one or more egress ports.
