摘要： One embodiment of the present invention provides a system for testing reachability between two nodes within a network. During operation, the system transmits a network-testing request frame from a source node to a destination node, and in response to receiving a network-testing response frame corresponding to the request frame, the system determines reachability of the destination node. The network-testing request or response frame is not processed on an Internet Protocol (IP) layer.

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 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 traffic management mechanism and 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 virtual cluster switch.

摘要： One embodiment of the present invention provides a switch. The switch includes a port to couple to a second switch. The switch also includes a control mechanism configured to maintain a set of configuration information for a virtual cluster switch which includes a number of member switches. The set of configuration information includes global configuration information for the virtual cluster switch and switch-specific configuration information for one or more member switches. In addition, the set of configuration information is replicated and stored at each member switch.

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： 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： 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 that facilitates name services in a virtual cluster switch. The switch includes a name service database indicating at least one media access control (MAC) address learned at a second switch. The switch also includes a control mechanism. During operation, the control mechanism distributes information on a locally learned MAC address to the second switch. In addition, the control mechanism receives information on a MAC address learned at the second switch.
