Assign interfaces to be managed by the controller
In a VTEP, explicitly assign interfaces for an OVSDB controller to manage.
Before you assign the interface, consider the following:
● The interface must be in Switchport Trunk mode.
● The interface must not be a member of any VLAN
● The interface must not be a member of a port-channel
When the above conditions are not met when assigning the interfaces to be managed by the controller, the system returns error
messages.
When the interface is assigned, you cannot:
● remove the interface from Switchport Trunk mode
● add the interface as a member of any VLAN
● remove the interface from the controller configuration if the interface has active port-scoped VLAN (Port,VLAN) pairs
configured by the controller
To assign an interface to be managed by the OVSDB controller:
1. Configure an interface from CONFIGURATION mode.
OS10(config)# interface ethernet 1/1/1
2. Configure L2 trunking in INTERFACE mode.
OS10(config-if-eth1/1/1)# switchport mode trunk
3. Configure the access VLAN assigned to a L2 trunk port in the INTERFACE mode.
OS10(config-if-eth1/1/1)# no switchport access vlan
4. Assign the interface to the controller.
OS10(config-if-eth1/1/1)# nve-controller
To view the controller information and the ports the controller manages, use the show nve controller command.

Service Nodes
In an NSX-provisioned VXLAN environment, service nodes replicate L2 broadcast, unknown-unicast, and multicast (BUM) traffic
that enter an OS10 VTEP to all other VTEPs. For the service node replication of BUM traffic to work, you need IP connectivity
between the service nodes and the VTEP, so that the BUM traffic from a VTEP reaches the other remote VTEPs via a VXLAN
overlay through the service nodes. The NSX controller manages a cluster of service nodes and sends the IP addresses of the
nodes to the VTEP through OVSDB protocol. The service node cluster provides redundancy, and also facilitates load balancing
of BUM traffic across service nodes.
The following shows BUM traffic replication in the controller-provisioned VXLAN environment:
