摘要： One embodiment of the present invention provides a switch system. The switch includes one or more ports on the switch configured to transmit packets encapsulated based on a first protocol. The switch further includes a control mechanism. During operation, the control mechanism forms a logical switch based on a second protocol, receives an automatically assigned identifier for the logical switch without requiring manual configuration of the identifier, and joins a Ethernet fabric.

摘要： One embodiment of the present invention provides a switch system. The switch includes a port that couples to a server hosting a number of virtual machines. The switch also includes a link tracking module. During operation, the link tracking module determines that reachability to at least one end host coupled to a virtual cluster switch of which the switch is a member is disrupted. The link tracking module then determines that at least one virtual machine coupled to the port is affected by the disrupted reachability, and communicates to the server hosting the affected virtual machine about the disrupted reachability.

摘要： One embodiment of the present invention provides a switch system. The switch includes a port profile which specifies a set of port configuration information. During operation, a control mechanism within the switch detects a source MAC address of an incoming frame and determines that the MAC address is associated with the port profile. The control mechanism then applies the port profile to a switch port on which the frame is received.

摘要： One embodiment of the present invention provides a switch. The switch includes an IP header processor and a forwarding mechanism. The IP header processor identifies a destination IP address in a packet encapsulated with an inner Ethernet header, a TRILL header, and an outer Ethernet header. The forwarding mechanism determines an output port and constructs a new header for the packet based on the destination IP address. The switch also includes a packet processor which determines whether (1) an inner destination media access control (MAC) address corresponds to a local MAC address assigned to the switch; (2) a destination RBridge identifier corresponds to a local RBridge identifier assigned to the switch; and (3) an outer destination MAC address corresponds to the local MAC address.

摘要： The entire FCoE fabric is a single virtual domain, even though there may be multiple FCFs and FDFs. The virtual domain is a different Domain_ID than any of the FCFs. In certain embodiments there are multiple FCFs, of which one is selected as the master or designated FCF. The master FCF performs normal fabric configuration in conjunction with the Fiber Channel fabric. The master FCF assigns the virtual domain FC node IDs and controls development of subdomain IDs. Virtual links are instantiated between the master FCF and other FCFs, between top level FDFs and the FCFs and between the FDFs at each of various levels. FDFs connected to ENodes proxy the master FCF for most FIP operations. FIP FLOGI and FDISC operations are handled by the master FDF, but the FDFs convert the FIP FLOGI requests to VD_FLOGI requests, which include information about the FDF handling the transaction.
摘要翻译：整个FCoE架构是单个虚拟域，尽管可能有多个FCF和FDF。虚拟域是与任何FCF不同的Domain_ID。在某些实施例中，存在多个FCF，其中一个被选择为主或指定的FCF。主FCF与光纤通道结构一起执行正常的光纤配置。主FCF分配虚拟域FC节点ID并控制子域ID的开发。虚拟链路在主FCF和其他FCF之间，在顶级FDF和FCF之间以及在各种级别的FDF之间实例化。连接到ENodes的FDF为大多数FIP操作代理主FCF。 FIP FLOGI和FDISC操作由主FDF处理，但FDF将FIP FLOGI请求转换为VD_FLOGI请求，其中包括有关处理事务的FDF的信息。

摘要： One embodiment of the present invention provides a switch. The switch includes a port that couples to a server hosting a number of virtual machines. The switch also includes a set of virtual port grouping information and a virtual port grouping mechanism. During operation, the virtual port grouping mechanism determines whether a frame is traveling from a virtual port group to the same virtual port group. If the frame is not traveling to the same virtual port group, the virtual port grouping mechanism prevents the frame from being forwarded.

摘要： One embodiment of the present invention provides a switch. The switch includes a storage and a lookup mechanism. The storage stores a first table that contains an entry corresponding to a media access control (MAC) address of a device and an identifier of a remote switch associated with the device. The storage also stores a second table that contains an entry indicating a local outgoing interface corresponding to the remote switch. The lookup mechanism identifies the local outgoing interface corresponding to the device based on the first table and the second table.

摘要： One embodiment of the present invention provides a system for detecting a path between two nodes. During operation, the system transmits a network-testing request frame, which includes a time-to-live (TTL) field within a Transparent Interconnection of Lots of Links (TRILL) header, from a source node to a destination node. In response to receiving a network-testing response frame sent from an intermediate node, the system increments the TTL value by 1 and re-transmits the network-testing frame to the destination node. In response to receiving a network-testing response frame sent from the destination node, the system determines a path between the source node and the destination node. The network-testing request or response frames is not processed on an Internet Protocol (IP) layer.
摘要翻译：本发明的一个实施例提供一种用于检测两个节点之间的路径的系统。在操作期间，系统发送网络测试请求帧，该帧包括从源节点到目的地节点的多个链路（TRILL）头部的透明互连中的生存时间（TTL）字段。响应于接收到从中间节点发送的网络测试响应帧，系统将TTL值递增1，并将网络测试帧重新发送到目的地节点。响应于接收到从目的地节点发送的网络测试响应帧，系统确定源节点和目的节点之间的路径。网络测试请求或响应帧不会在Internet协议（IP）层上处理。
