Mapping the Router Network Interfaces to vNICs
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. The figure below shows the relationship between the
vNICs and the Cisco CSR 1000v router interfaces.
Figure 6: vNICs Mapped to Cisco CSR 1000v Router Interfaces
After the Cisco CSR 1000v boots, you need to display the mapping between the logical interface on the router
with the vNIC and the vNIC MAC address using the show platform software vnic-if interface-mapping
command. The display for this command is different depending on your Cisco IOS XE release version. (Note:
For Cisco IOS XE Release 3.11 or later, the GigabitEthernet0 interface is no longer supported.)
