Chapter 1 Overview Virtualization Interfaces Send document comments to [email protected] 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.
