Cisco Nexus 7000 Series NX-OS Interfaces Configuration Guide, Release 5.x

Chapter 1 Overview
Virtualization Interfaces
Virtualization Interfaces
You can create multiple virtual device contexts (VDCs). Each VDC is an independent logical device to
which you can allocate interfaces. Once an interface is allocated to a VDC, you can only configure that
interface if you are in the correct VDC. For more information on VDCs, see the Cisco Nexus 7000 Series
NX-OS Virtual Device Context Configuration Guide, Release 5.x.
High Availability for Interfaces
Interfaces support stateful and stateless restarts. A stateful restart occurs on a supervisor switchover.
After the switchover, Cisco NX-OS applies the runtime configuration after the switchover.
Licensing Requirements for Interfaces
IP tunnels and vPCs require the Enterprise Services license. You must install this license on every system
that enables IP tunnels. All other interfaces do not require a license.
