摘要： A method for determining that a defect applies to a network device that includes receiving, at a monitoring module, network device information from the network device. The network device information includes state information for the network device and does not include hardware and software version information. The method includes storing, in a network device database, the network device information from the network device and receiving, at the monitoring module, defect information about a defect. The defect information includes network device criteria specifying what state information is required for a network device to be affected by the defect. The method includes storing the defect information in a defect database, determining that the defect applies to the network device based on analyzing the network device information and the defect information from their respective databases, and, based on the determination, informing a defect alert recipient that the defect applies to the network device.

摘要： A system and method for route health injection using virtual tunnel endpoints. The method includes detecting, by a virtual tunnel endpoint (VTEP), that a new host is connected to the VTEP, where the VTEP is executing on the network device. The method further includes, based on the detecting, generating by the VTEP, a new route for the new host, where the new route is at least a longer match for the new host than currently existing routes for the new host, and providing the new route to a default gateway for the new host.

摘要： A method for transmitting MAC frames. The method includes receiving, by a first switch in the MLAG domain, a first media access control (MAC) frame from an external device, wherein the external device is directly connected to the first switch, where the MLAG domain consists of the first switch and the second switch. The method further includes making a first determination that the external device is not a singly-connected external device and based on the first determination, encapsulating the first MAC frame in a first VXLAN frame using a first virtual tunnel endpoint (VTEP), where the first VXLAN frame comprises a virtual VTEP Internet Protocol (IP) address, where the virtual VTEP IP address is associated with the MLAG domain. The method further includes transmitting the first VXLAN frame to an IP fabric, where the first switch is directly connected to the IP fabric.

摘要： A method for virtual extensible local area network (VXLAN) encapsulation. The method includes receiving a first augmented MAC frame on a first ingress port of a first network device, where the first augmented MAC frame includes a first egress port ID (EPID), a first ingress port ID (IPID), and a first MAC frame. The method further includes identifying a first destination VXLAN tunnel endpoint (VTEP) internet protocol (IP) address based on the first EPID, where the first destination VTEP IP address is associated with a first destination VTEP. The method further includes identifying a source VTEP IP address based on the first IPID, performing VXLAN encapsulation of the first MAC frame to obtain a VXLAN frame, and sending the VXLAN frame to the first destination VTEP via a first egress port of the first network device.

摘要： A method for distributing VXLAN information that includes receiving, from a first leaf network device and by a first intermediate network device, first VXLAN information associated with a first computing device. The first leaf network device is connected to the first computing device and includes a first database server. The first intermediate network device includes a first database client and a second database server. The method also includes storing the first VXLAN information in a first database entry on the first intermediate network device; sending, by a second database server, a first copy of the first database entry to a higher-tier network device, and sending, by the first database client, a second copy of the first database entry to a third database server. The third database server is executing on a second leaf network device.

摘要： A method and apparatus of a device that determines a cause and effect of congestion in this device is described. In an exemplary embodiment, the device measures a queue group occupancy of a queue group for a port in the device, where the queue group stores a plurality of packets to be communicated through that port. In addition, the device determines if the measurement indicates a potential congestion of the queue group, where the congestion prevents a packet from being communicated within a time period. If potential congestion exists on that queue group, the device further gathers information regarding packets to be transmitted through that port. For example, the device can gather statistics packets that are stored in the queue group and/or new enqueue packets.

摘要： A method and apparatus of a network element that authenticates a field replaceable unit of the network element is described. The network element authenticates a field replaceable unit of the network element by generating a nonce. In addition, the network element generates a signature using a nonce and a private encryption key that is securely stored in the field replaceable unit. The network element further verifies the signature using a public encryption key that is a pair to the private encryption key and is not securely stored in the field replaceable unit. If the field replaceable unit is verified, the network element uses the field replaceable unit to operate the network element. Otherwise, the network element disables the field replaceable unit.

摘要： In general, embodiments of the invention relate to routing packets between servers in different layer 2 domains. More specifically, embodiments of the invention relate to using overlay routing mechanisms in an Internet Protocol (IP) fabric to enable communication between servers in different layer 2 domains to communication. The overlay routing mechanisms may include direct routing, indirect routing, naked routing, or a combination thereof (e.g., hybrid routing).
