摘要： A method for automatically generating a network subnet configuration, monitors IP Address Resolution Protocol (ARP) frames on the network and builds and maintains a table which includes a list of learned subnets, the ports or forwarding domain associated with each of the learned subnets and a mask associated with each learned subnet for identifying hosts belonging to the subnet. The from and to IP addresses from intercepted IP ARP frames are examined to determine if the IP addresses belong in any of the learned subnets. If neither IP address belongs to an existing learned subnet a new learned subnet is established. The subnet includes the common prefix bits of both IP addresses, a mask identifying those bits and the port over which the ARP frame was received. If only one IP address belong to a learned subnet, the mask associated with that subnet is modified to include the common prefix bits of both IP addresses and the forwarding domain is adjusted. If the two IP addresses belong to different learned subnets, the two subnets are combined.

摘要： Apparatuses and methods to request multicast membership information in a distributed switch are provided. A particular method may include requesting multicast membership information of a group identified by a multicast destination address in a distributed switch. The distributed switch may include a plurality of distributed switch elements with a plurality of switch forwarding units. The method may generate a miss event indicating that the multicast destination address is unregistered in a switch forwarding unit of a distributed switch element and there is a need for the multicast membership information. The method may also request the multicast membership information of the multicast destination address in response to the miss event. The method may further initiate a query for the multicast membership information of the multicast destination address in response to the request.

摘要： A network processor includes first communication protocol ports that each support ‘M’ minimum size packet data path traffic on ‘N’ lanes at ‘S’ Gigabits per second (Gbps) and traffic with different communication protocol units on ‘n’ additional lanes at ‘s’ Gbps. The first communication protocol ports support access to an external coprocessor using parsing logic located in each of the first communication protocol ports. The parsing logic, during a parsing period, is configured to send a request to the external coprocessor at reception of a ‘M’ size packet and to receive a response from the external coprocessor. The parsing logic sends a request maximum ‘m’ size byte word to the external coprocessor on one of the additional lanes and receives a response maximum ‘m’ size byte word from the external coprocessor on the one of the additional lanes while complying with the equation N×S/M=

摘要： A mechanism is provided for merging in a network processor results from a parser and results from an external coprocessor providing processing support requested by said parser. The mechanism enqueues in a result queue both parser results needing to be merged with a coprocessor result and parser results which have no need to be merged with a coprocessor result. An additional queue is used to enqueue the addresses of the result queue where the parser results are stored. The result from the coprocessor is received in a simple response register. The coprocessor result is read by the result queue management logic from the response register and merged to the corresponding incomplete parser result read in the result queue at the address enqueued in the additional queue.

摘要： A system and method in accordance with the present invention allows for an adapter to be utilized in a server environment that can accommodate both a 10 G and a 1 G source utilizing the same pins. This is accomplished through the use of a high speed serializer/deserializer (high speed serdes) which can accommodate both data sources. The high speed serdes allows for the use of a relatively low reference clock speed on the NIC to provide the proper clocking of the data sources and also allows for different modes to be set to accommodate the different data sources. Finally the system allows for the adapter to use the same pins for multiple data sources.
