Virtual Network Interface Cards (vNICs)

OpenStack Cloud Instances with GvTAP Agents can be configured with one or more vNICs.

•

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

•

Multiple vNICs—If there are two or more interfaces configured on the instance with the G-vTAP agent, the G-vTAP agent 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.

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