Virtual Network Interface Cards (vNICs)

OpenStack Cloud Instances with UCT-V can be configured with one or more vNICs.

■

Single vNIC—If there is only one interface configured on the instance with the UCT-V, the UCT-V sends the mirrored traffic out using the same interface.

■

Multiple vNICs—If there are two or more interfaces configured on the instance with the UCT-V, the UCT-V monitors any number of interfaces. It provides an option to send the mirrored traffic out using any one of the interfaces or using a separate, non-monitored interface. When multiple interfaces are added to the controller, floating IP is used to make the first interface as management interface.

Note:  vNICs are only applicable if the UCT-V is installed on the instances being monitored. It is not applicable for OVS Mirroring or OVS Mirroring +DPDK.
