  • Maintaining balance of active links across network devices in a double-sided virtual port-channel environment
    Patent number: 8514743
    Abstract: In one embodiment, a method includes configuring a first network device for operation in a first logical group with a second network device, receiving information from other network devices configured for operation in a second logical group, the information uniquely identifying each of the other network devices within the second logical group, and assigning a priority to each link connecting the first network device to the second logical group network devices. A portion of the links are selected as active links based on the link priorities and the link priorities are assigned such that a balance of active links is maintained across the second logical group network devices. An apparatus for maintaining a balance of active links across the network devices is also disclosed.
