  • Duplicate internet protocol address resolution in a fragmented switch stack environment
    Patent number: 8213297
    Abstract: Embodiments of the present invention provide a novel and non-obvious method, system and computer program product for an Internet protocol (IP) address resolution process during an original switch stack fragmentation, by employing a secondary communication link. A method for IP address resolution of a fragmented switch stack over a secondary communication link (e.g., an I2C bus) can include detecting a first switch stack fragment by a first stack master, detecting a second switch stack fragment by a second stack master, disabling all switches of the first switch stack fragment and the second switch stack fragment, connecting the first stack master and the second stack master to a stack management module via a secondary communication link, and electing one stack fragment to use the IP address of the original switch stack based on at least one election criteria.
