The pre-provisioning feature allows you to preconfigure interfaces before inserting or attaching a module to a Cisco Nexus 5000 Series switch. If a module goes offline, you can also use pre-provisioning to make changes to the interface configurations for the offline module. When a pre-provisioned module comes online, the pre-provisioning configurations are applied. If any configurations were not applied, a syslog is generated. The syslog lists the configurations that were not accepted.
In some Virtual Port Channel (vPC) topologies, pre-provisioning is required for the configuration synchronization feature. Pre-provisioning allows you to synchronize the configuration for an interface that is online with one peer but offline with another peer.


About NX-OSv 9000

The NX-OSv 9000 is a virtual platform that is designed to simulate the control plane aspects of a network element running Cisco Nexus 9000 software. The NX-OSv 9000 shares the same software image running on Cisco Nexus 9000 hardware platform although no specific hardware emulation is implemented. When the software runs as a virtual machine, line card (LC) ASIC provisioning or any interaction from the control plane to hardware ASIC is handled by the NX-OSv 9000 software data plane.
