  • Virtual port support in a logical switch architecture
    Patent number: 10277422
    Abstract: A tool for assigning virtual port channels to one or more logical switch routers in a distributed system. The tool receives, by one or more computer processors, a request to assign a virtual port channel to a second logical switch router. The tool sends, by one or more computer processors, a request to negotiate a link-down on the channel on a first logical switch router to a universal fiber port on the first logical switch router for processing. The tool sends, by one or more computer processors, a request to create the channel on the second logical switch router to a second interface manager on the second logical switch router for processing. The tool sends, by one or more computer processors, a request to negotiate a link up on the channel on the second logical switch router to the universal fiber port on the first logical switch router for processing.
