Mapping

A FlexNIC can also be configured to support OS VLAN tag mapping to different VC networks, as
shown in Figure 5. The combination of the outer VLAN tag and the inner OS tag are used to map an
Ethernet packet to a particular vNet. Double-tagged packets are mapped to vNet destinations without
exiting the VC domain.
