Controller-provisioned VXLAN
OS10 supports VXLAN provisioning using an Open vSwitch Database (OVSDB) controller. Currently, the only supported
OVSDB controller is the VMware NSX controller. In a controller-provisioned VXLAN, the controller manages VXLAN-related
configurations and other control-plane operations, such as MAC address propagation.
NOTE: Controller-provisioned VXLAN is not supported on S3048-ON switches. Also, controller-provisioned VXLAN is not
supported on VTEPs configured as peers in a VLT domain. Only VTEPs in standalone mode are supported.
Controller-provisioned VXLAN
The NSX controller communicates with an OS10 VTEP using the OVSDB management protocol over a Secure Sockets Layer
(SSL) connection. Establishing the communication between the controller and VTEP involves generating the SSL certificate at a
VTEP and copying the certificate to the NSX controller. After SSL authentication, a secure connection over SSL is established
between the controller and the VTEP. The VTEP then receives and processes the configuration data from the controller.
Controller-provisioned VXLAN: Manual configuration
You must manually configure the underlay network using the OS10 CLI:
● Configure the L3 protocol used for underlay routing. Underlay reachability to VTEP peers is learned using the configured
routing protocol.
● Configure the loopback interface in the default VRF that is used as the VTEP source IP address for controller-based
provisioning.
● Assign the VTEP interfaces to be managed by the controller.
Controller-provisioned VXLAN: Automatic provisioning
The controller automatically provisions:
● L2 overlay network
● VXLAN virtual networks, including remote VTEP source addresses
● Local access ports in a virtual network
An OS10 VTEP sends the addition or deletion of server MAC addresses at the VXLAN access port to the NSX controller
using the OVSDB protocol. The controller then propagates the information to VTEP peers. The VTEPs program their
forwarding tables accordingly.
Configure controller-provisioned VXLAN
To configure the NSX controller, follow these steps on each OS10 VTEP:
