Virtual Network Interface Cards (vNICs)

You can configure OpenStack Cloud Instances with UCT-V to use one or more virtual network interface cards (vNICs):

Single vNIC: If the instance has only one interface, UCT-V sends mirrored traffic through that same interface.

Multiple vNICs: If the instance has two or more interfaces, 

• UCT-V monitors any number of interfaces. 

• You can send the mirrored traffic out using one of the interfaces or using a separate, non-monitored interface. 

• When you add multiple interfaces to the controller, the system uses a floating IP to designate the first interface as the management interface.

Note:  vNICs are only applicable if the UCT-V is installed on the monitored instances. They do not apply to OVS Mirroring or OVS Mirroring +DPDK.
