Configuring Module Pre-ProvisioningThis chapter describes how to configure pre-provisioning for offline interfaces or modules in the Cisco Nexus5000Series switch.This chapter includes the following sections:•Information About Module Pre-Provisioning,page1•Guidelines and Limitations,page2•Enabling Module Pre-Provisioning,page2•Removing Module Pre-Provisioning,page3•Verifying the Pre-Provisioned Configuration,page4•Configuration Examples for Pre-Provisioning,page5Information About Module Pre-ProvisioningThe pre-provisioning feature allows you to preconfigure interfaces before inserting or attaching a module toa Cisco Nexus5000Series switch.If a module goes offline,you can also use pre-provisioning to make changesto the interface configurations for the offline module.When a pre-provisioned module comes online,thepre-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 configurationsynchronization feature.Pre-provisioning allows you to synchronize the configuration for an interface that isonline with one peer but offline with another peer.Supported HardwareThe pre-provisioning feature supports the following hardware:•N2K-C2148T Fabric Extender48x1G4x10G

LAN,4x Fiber Channel •N5K-M1600Cisco 6-port 10Gigabit Ethernet SFP Module 6x SFP Upgrades and DowngradesWhen upgrading from Cisco NX-OS Release 4.2(1)N2(1)and earlier releases to Cisco NX-OS Release 5.0(2)N1(1),there are no configuration implications.When upgrading from a release that supportspre-provisioning to another release that supports the feature including InService Software Upgrades (ISSU),pre-provisioned configurations are retained across the upgrade.When downgrading from an image that supports pre-provisioning to an image that does not support pre-provisioning,you are prompted to remove pre-provisioning configurations.Guidelines and LimitationsPre-provisioning has the following configuration guidelines and limitations:•When a module comes online,commands that are not applied are listed in the syslog.•If a slot is pre-provisioned for module A and if you insert module B into the slot,module B does not come online.•There is no MIB support for pre-provisioned interfaces.•Cisco DCNM is not supported.Enabling Module Pre-ProvisioningYou can enable pre-provisioning on a module that is offline.Enter the provision model model command in module pre-provisionmode.After enabling pre-provisioning,you can configure the interfaces as though they are online.NoteSUMMARY STEPS1.configuration terminal2.slot slot3.provision model
