摘要： When testing or validating a hardware system, a script file representing a portion of the firmware may be used to test the system instead of using the firmware code itself. For example, the script file may be plurality of register commands that perform the same initialization sequence as the firmware. Before connecting the hardware system to firmware drivers, the script file may be used to debug the initialization sequence. Instead of generating this script file manually, a firmware testing tool may be used. While executing the firmware, the tool may record the different register access commands performed during the initialization process. The script file is then generated programmatically using these recorded commands without requiring input from the system designer. The generated script file may then be tested on the hardware system to determine whether the command sequence in the script file forces the hardware system into the desired state.
摘要翻译： 当测试或验证硬件系统时，可以使用表示固件部分的脚本文件来测试系统，而不是使用固件代码本身。 例如，脚本文件可以是执行与固件相同的初始化序列的多个寄存器命令。 在将硬件系统连接到固件驱动程序之前，脚本文件可用于调试初始化顺序。 可以手动生成此脚本文件，而不是使用固件测试工具。 在执行固件时，该工具可以记录在初始化过程中执行的不同的寄存器访问命令。 然后使用这些记录的命令以编程方式生成脚本文件，而不需要系统设计者的输入。 然后可以在硬件系统上测试生成的脚本文件，以确定脚本文件中的命令序列是否迫使硬件系统进入所需状态。

摘要： Techniques are disclosed to reduce crossover between traffic from switch elements of different switch domains in a distributed switch. Addition of a first switch element to the distributed switch is detected. The distributed switch includes multiple switch elements at least subsequent to the addition, and each switch element has a switch element identifier and a fabric identifier. The respective fabric identifiers of the first switch element and of a second switch element are retrieved. The second switch element is communicably connected to the first switch element via a link, and the link is configured to allow only command traffic to be transmitted via the link. Upon a determination that the fabric identifier of the first switch element does not match the fabric identifier of the second switch element, then no command is issued specifying to reconfigure the link to allow at least one additional traffic type, different from command traffic.

摘要： A system and method performs packet analysis in a distributed communication network. Packet processors tap into data packet flow at various points in the distributed network. The packet processors processes data packets from the packet flow and select a set of packets using a packet signature function and packet selection criteria. A packet record is created by each packet processor and sent to other packet processors in the distributed network. The other packet processors add data to the packet record for the same set of packets. The packet records are analyzed to gather comparative data to identify problems in the network.

摘要： The different switch modules making up a distributed virtual switch may route configuration commands for hardware resources to different modules within the distributed switch using a distribution and routing layer. At least one of the switch modules maintains a routing table that defines which switch modules are responsible for which hardware resources. The switch module uses the routing tables to forward the commands on the distribution and routing layer to the responsible switch module which then ensures that the relevant hardware resources are configured.

摘要： Techniques are provided for packet routing in a distributed network switch. The distributed network switch includes multiple switch modules operatively connected to one another, and each switch module includes multiple bridge elements and a management controller. In one embodiment, a shared interface routing (SIR) framework is provided that includes an analysis and bifurcation layer and at least one packet interface. A packet is received over a first logical network and via a physical port, the packet being destined for at least a first application executing on the management controller. The analysis and bifurcation layer analyzes the packet and sends the packet to the packet interface, which then routes the packet to the first application.

摘要： Techniques are provided for packet routing in a distributed network switch. The distributed network switch includes multiple switch modules operatively connected to one another, and each switch module includes multiple bridge elements and a management controller. In one embodiment, a shared interface routing (SIR) framework is provided that includes an analysis and bifurcation layer, at least one packet interface, and an analysis assist layer. A packet is received over a first logical network and via a physical port, the packet being destined for at least a first application executing on the management controller. The analysis assist layer analyzes the packet to determine a reason code to assign to the packet. The analysis and bifurcation layer then analyzes the packet based at least in part on the reason code.
