A slave device adapted to couple to a master processor and including an error handler and a communication controller. The error handler is configured to detect errors internal to the slave device and, in response to detecting at least one error and independent of the master processor, configured to select an error recovery operation based on the at least one detected error and to initiate and perform the selected error recovery operation. The communication controller is configured to communicate with the master processor according to a master/slave protocol, and configured to maintain the master/slave protocol during performance of the selected error recovery operation by the error handler.

In one embodiment, a system for configuring an interconnect device includes a non-volatile storage device to store configuration data associated with the interconnect device and a configuration interface to request the configuration data from the non-volatile storage device. Further, the system includes an initialization module to query the configuration interface for the configuration data and to distribute the configuration data provided by the configuration interface to multiple units within the interconnect device.

A system for supporting management operations associated with an interconnect device includes a port of the interconnect device to maintain authentication data that facilitates authorization of a management operation and a configuration switch coupled to the port to generate a reset signal in response to an operator's command. The port is operable to reset the authentication data upon receiving the reset signal from the configuration switch.

A method and management port for an indirect loop protocol associated with an interconnect device. In one embodiment, a method to handle a request sent to an interconnect device includes receiving the request at a destination switch from a host network adapter; generating a response to the request in the destination switch; and returning the response to the host network adapter, wherein the destination switch includes a management port for addressing the interconnect device that implements an indirect loop protocol.

A networking system includes a plurality of ports, each adapted to send and receive data. A switch core has a first channel configured to receive a logical input flow from each of the plurality of input ports, and has a second channel configured to receive a raw input flow from each of the plurality of input ports. Each logical input flow is carried by its corresponding raw input flow. A plurality of port mirrors are selectable from the plurality of ports. Each of the plurality of port mirrors is configured to produce a duplicate copy of at least one of the logical input flow and the raw input flow available at a selected port.

A method of port numbering in an interconnect device includes loading a port configuration value from a memory device. One or more ports and subports are enabled according to the configuration value. Contiguous logical port numbers are assigned to the one or more ports and subports included in the interconnect device. A mapping request is received; and a mapped response associated with the mapping request is provided to an entity.

A method and system to arbitrate between a plurality of resource requests are disclosed. In each arbitration within a current round of arbitration, a winning request is identified based on a priority associated with each requester participating in the arbitration and a set of values stored in a mask register. In response to identifying the winning request, a mask register value corresponding to a requestor of the winning request is updated to disqualify this requestor from further participation in the current round of arbitration. When the current round of arbitration completes, the set of values in the mask register is reset to allow each requestor to participate in the next round of arbitration. The current round of arbitration begins when each requester is qualified to participate in the current round of arbitration and completes when every participating requestor has been disqualified.

Mask-based round robin arbitration

In one embodiment, a method for facilitating detection of, and recovery from, data contamination in a non-volatile storage device coupled to an interconnect device includes receiving data to be written to a content area on a non-volatile storage device coupled to an interconnect device, updating a contamination indicator stored in a supplemental area of the non-volatile storage device with a first value indicating potential data contamination in the content area, and transferring the data to the non-volatile storage device for a write to the content area. Further, if a determination is made that the write of the transferred data has completed, the contamination indicator is updated with a second value indicating lack of data contamination in the content area.

NVRAM control protocol

In one embodiment a method for processing an incoming packet in a port of an interconnect device includes speculatively forwarding the incoming packet to multiple buffers within the port prior to determining which of the multiple buffers is a target buffer for the packet, decoding the packet, and determining which of the multiple buffers is the target buffer for the packet using the decoded packet. The method further includes notifying an agent associated with the target buffer that the target buffer is an intended owner of the data packet. In one embodiment, agents associated with the multiple buffers are designated to process packets that are not subject to a credit-based flow control method.

Speculative loading of buffers within a port of a network device

A method and system to arbitrate requests of a plurality of ports of an interconnect device are provided. Every port receives combined pending request data that includes a pending request indicator associated with each of the plurality of ports. Each pending request indicator specifies whether a corresponding port has a pending request that needs to be submitted to a request bus of the interconnect device. Further, at each port, a turn to submit a request to the request bus is allocated to one of the plurality of ports based on the combined pending request data, a set of values stored in a mask register and a priority scheme associated with the plurality of ports.
