  • Identifier assignment to a new switch in a switch group
    Patent number: 10038592
    Abstract: One embodiment of the present invention provides a switch. The switch includes a switch group module, a persistent storage module, and an allocation module. The switch group module maintains a membership in a switch group. The switch group includes a plurality of switches and operates as a single switch. The persistent storage module stores configuration information associated with the switch group in a data structure in a local persistent storage. The allocation module determines that a second switch is in a default mode and obtains a switch identifier from the persistent storage based on a switch media access control (MAC) address of the second switch. The allocation module then constructs a control message, which is destined for the second switch and includes the switch identifier and a switch group identifier of the switch group.

  • Fast reboot for a switch
    Patent number: 9524173
    Abstract: One embodiment of the present invention provides a switch. The switch includes a packet processor, a persistent storage module, and a boot-up management module. The packet processor identifies a switch identifier associated with the switch in the header of a packet. The persistent storage module stores configuration information of the switch in a first table in a local persistent storage. This configuration information is included in a configuration file, and the first table includes one or more columns for the attribute values of the configuration information. The boot-up management module loads the attribute values to corresponding switch modules from the first table without processing the configuration file.
