20140101302 | Techniques for Scalable and Foolproof Virtual Machine Move Handling with Virtual Port Channels - Techniques are provided for managing movements of virtual machines in a network. At a first switch, a virtual machine (VM) is detected. The VM is hosted by a physical server coupled to the first switch. A message is sent to other switches and it indicates that the VM is hosted by the physical server. When the first switch is paired with a second switch as a virtual port channel (vPC) pair, the message includes a switch identifier that identifies the second switch. A receiving switch receives the message from a source switch in the network comprising a route update associated with the VM. A routing table of the receiving switch is evaluated to determine whether the host route is associated with a server facing the physical port. The message is examined to determine it contains the switch identifier. | 04-10-2014 |
