  • Managing virtual port channel switch peers from software-defined network controller
    Patent number: 10749742
    Abstract: Systems, methods, and computer-readable storage media for configuring a virtual port channel (VPC) domain. The disclosed technology involves determining that a first switch and a second switch are connected in a VPC domain, determining that the first switch is in a primary role, and determining a unique identifier for the first switch, a VPC portchannel number for the first switch, and an orphan port number for the first switch. Also, the first switch receives a unique identifier, a VPC portchannel number, and an orphan port number for the second switch. The first switch can associate the VPC portchannel number for the second switch and the VPC portchannel number for the first switch with a unified VPC portchannel number and create a first unique orphan port number for the first switch and a second unique orphan port number for the second switch.

  • Authentication for VLAN tunnel endpoint (VTEP)
    Patent number: 9979711
    Abstract: A first network device configured as a first Virtual Local Area Network (VLAN) Tunnel Endpoint (VTEP) may receive a packet from a second network device. The first VTEP may determine that the second network device is a second VTEP and has not been established as a peer VTEP to the first VTEP. The first VTEP may maintain a status for the second network device as authentication pending, receive an authentication packet from the second network device and authenticating the second network device as a peer VTEP using the authentication packet.
