摘要： It is determined whether a packet is a multicast packet, and an index to a database is selected from i) a first candidate index determined based on header information of the packet, or ii) a second candidate index determined based on the header information, based on whether the packet is a multicast packet. Information is retrieved from the database using the index, and the header information is compared with information retrieved from the database. Further information retrieved from the database is used to determine one or more ports via which the packet should be transmitted when the header information matches the information retrieved from the database.

摘要： Systems, methods, and other embodiments associated with wake-on-frame mechanisms are described. According to one embodiment, an apparatus includes a packet source configured to send packets to a frame processing device and a wake-on-frame mechanism that is selectable by the frame processing device between an enabled state and a disabled state. If the wake-on-frame mechanism is in the enabled state, a packet source that has a frame to send to the frame processing device sends a wake signal to the frame processing device prior to sending the packet. The packet source sends the packet to the frame processing device after receiving a ready signal from the frame processing device.

摘要： A console is provided and includes a switch and a network device. The network device includes a switch port, first network ports, and a controller. The switch is separate from the network device. Each of the first network ports receives a frame of data, and inserts source information into the frame of data. The source information in each frame of data identifies the first network port that received the frame of data. The controller transfers each frame of data, including the source information, to the switch via the switch port. The switch: adds to each frame of data, destination information identifying one or more of the first network ports; and transfers each frame of data, including the source and destination information, to the switch port. The controller transfers each frame of data, received from the switch port, to the first network ports.

摘要： A network switching device comprises first and second ports. A queue communicates with the second port, stores frames for later output by the second port, and generates a congestion signal when filled above a threshold. A control module selectively sends an outgoing flow control message to the first port when the congestion signal is present, and selectively instructs the second port to assert flow control when a flow control message is received from the first port if the received flow control message designates the second port as a target.

The controller is configured to, in response to the transmitter terminating the transmission of the first frame, increment respective attempt counts for a first class of service associated with the first frame and all classes of service lower than the first class of service, determine whether any of the respective attempt counts is greater than a predetermined attempt threshold, and, in response to any of the respective attempt counts being greater than the predetermined attempt threshold, discard frames having the first class of service and frames having any of the classes of service lower than the first class of service.

摘要： An apparatus including a port to transmit first frames and receive second frames over a communication channel, the port including a collision detect circuit and a duplex mismatch circuit. The collision detect circuit detects collisions on the communication channel between the first frames and the second frames. The duplex mismatch circuit declares a duplex mismatch when the communication channel was established without attempting auto-negotiation, the port is in a half-duplex mode, and the collision detect circuit detects a very late collision involving one of the first frames. The very late collision occurs after a predetermined amount of data has been transmitted in the one of the first frames. The duplex mismatch indicates that a full-duplex mode is used with respect to the second frames.
