Abstract: A clustered network may include a plurality of switch boxes where a master switch box may communicate and control hardware devices in remote switch boxes. The switch boxes in the network may each include a multiplexer, for example, a field programmable array (FPGA) that may process message requests related to hardware devices of a switch box. If the hardware device is in a remote switch box, then the FPGA of the master switch box may process the status data from the remote switch box so that a local processor in the master switch box can read the status data.

Abstract: A switching network includes an upper tier including a master switch and a lower tier including a plurality of lower tier entities. The master switch includes a plurality of ports each coupled to a respective one of the plurality of lower tier entities. Each port includes a plurality of virtual ports each corresponding to a respective one of a plurality of remote physical interfaces (RPIs) at the lower tier entity coupled to that port. Each port also includes a receive interface that, responsive to data traffic from a particular lower tier entity, queues the data traffic to the virtual port that corresponds to the RPI on the particular lower tier entity that was the source of the data traffic. The master switch further includes a switch controller that switches data traffic from the virtual port to an egress port from which the data traffic is forwarded.

Abstract: A switching network includes first, second and third switches coupled for communication, such that the first and third switches communicate data traffic via the second switch. The first switch is operable to request transmission credits from the third switch, receive the transmission credits from the third switch and perform transmission of data traffic in reference to the transmission credits. The third switch is operable to receive the request for transmission credits from the first switch, generate the transmission credits and transmit the transmission credits to the first switch via the second switch. The second switch is operable to modify the transmission credits transmitted by the third switch prior to receipt of the transmission credits at the first switch.

Abstract: The mode of operation in which a port is configured to operate may be selected so that the manner in which the port will interpret a loss of signal on a receive fiber may be specified. In an immediate mode, the port will interpret a loss of signal on a receive fiber as an indication of a fault on the transmit fiber (or interfaces associated with the transmit fiber) and will immediately shut its transmit interface down. In a multiple cycle detection mode, the port will not immediately interpret a loss of signal on a receive fiber as an indication of a fault on the transmit fiber, but rather will begin monitoring the receive fiber to look for a specified loss of signal pattern on the receive fiber. In this mode the port will interpret a repetitive loss of signal on the receive fiber as an indication of a fault on the transmit fiber. By providing a mode selector, the manner in which the ports are configured to operate may be adjusted individually, as a group, or globally.

Abstract: Port mirroring in a clustered network may be performed between a local switch and a remote switch. A port in the remote switch may be designated a mirrored port where data traffic passing there through can be copied and sent to a mirror-to-port on the local switch. In a virtual local area network (VLAN) environment, data frames of the copied traffic may include a VLAN header identifying the local switch so that routing of the data frames through the network may direct the data frames for monitoring at the local switch.

Abstract: A switch for a switching network includes a plurality of ports for communicating data traffic and a switch controller that controls switching between the plurality of ports. The switch controller selects a forwarding path for the data traffic based on at least topological congestion information for the switching network. In a preferred embodiment, the topological congestion information includes sFlow topological congestion information and the switch controller includes an sFlow client that receives the sFlow topological congestion information from an sFlow controller in the switching network.

Abstract: Each of first and second bridges of a data network having respective links to an external node implement a network bridge component that forwards traffic inside the data network and a virtual bridge component that forwards traffic outside of the data network. A virtual bridge is formed including the virtual bridge components of the first and second bridges and an interswitch link (ISL) between the virtual bridge components of the first and second bridges. Data frames are communicated with each of multiple external network nodes outside the data network via a respective one of multiple link aggregation groups all commonly supported by the virtual bridge.

Abstract: A switch of a data network implements both a bridge and a virtual bridge. In response to receipt of a data frame by the switch from an external link, the switch performs a lookup in a data structure using a source media access control (SMAC) address specified by the data frame. The switch determines if the external link is configured in a link aggregation group (LAG) and if the SMAC address is newly learned. In response to a determination that the external link is configured in a LAG and the SMAC address is newly learned, the switch associates the SMAC with the virtual bridge and communicates the association to a plurality of bridges in the data network.
