Mapping the Router Network Interfaces to Virtual Network Interface Cards

The Cisco CSR 1000V maps the GigabitEthernet network interfaces to the logical virtual network interface card (vNIC) name assigned by the VM. The VM in turn maps the logical vNIC name to a physical MAC address.

When the Cisco CSR 1000V is booted for the first time, the router interfaces are mapped to the logical vNIC interfaces that were added when the VM was created. Figure 10-1shows the relationship between the vNICs and the Cisco CSR 1000V router interfaces.

Note In Cisco IOS XE Release 3.10S and earlier, the first vNIC added is automatically mapped to the GigabitEthernet0 management interface. All subsequent vNICs added are mapped to router interfaces. Support for the GigabitEthernet0 interface was removed in Cisco IOS XE Release 3.11S.
