TRANSLATING MEDIA ACCESS CONTROL (MAC) ADDRESSES IN A NETWORK HIERARCHY

摘要

In one embodiment a method includes receiving a packet including a destination media access control (MAC) address field having a MAC address of a hypervisor and a destination Internet protocol (IP) address field having an IP address of a virtual machine (VM) coupled to the hypervisor. The method further determines a MAC address of the VM using the IP address of the VM and applies the VM MAC address to the destination MAC address field of the packet to forward the packet to the VM.

主权项

1. A method comprising:
receiving, in a hypervisor, a request to create a virtual machine (VM); instantiating, by the hypervisor, the VM on a server, including creating a provisioning manifest for the VM; receiving, in the hypervisor, from a switch of a rack including the server, a packet including a destination media access control (MAC) address field having a MAC address of the hypervisor and a destination Internet protocol (IP) address field having an IP address of the VM; determining, in the hypervisor, a MAC address of the VM using the IP address of the VM; and replacing, in the hypervisor, the MAC address of the hypervisor with the MAC address of the VM and forwarding the packet to the VM from the hypervisor, wherein the MAC address is not exposed to the switch.
