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 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 switching system. The switching system includes a Transparent Interconnection of Lots of Links (TRILL) header processor and an Internet Protocol (IP) header processor. The TRILL header processor is configured to identify a virtual routing bridge (RBridge) identifier in a packet, and the IP header processor is configured to identify a virtual IP address in the packet. The virtual IP address is assigned to a virtual IP router associated with the virtual RBridge identifier.

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 Fibre 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 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.
