Abstract
Techniques for authenticating and enforcing differentiated policies for a virtual machine (VM) executing in bridge mode on a host device are described. In an example method a fabric edge device determines a MAC address of the VM executing on the host device. The fabric edge device transmits an access request to create a session for the VM to an authentication server. The fabric edge device receives an indication that the VM is authenticated and a session for the VM has been created from the authentication server. The authentication server determines a policy to apply to packets communicated from the VM and assigns an IP address to the VM to create a MAC-IP binding for the VM. The fabric edge device applies the policy for the VM to packets with a source IP address corresponding to an IP address assigned to the VM.
