The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality.

Chapter: Working with Inventory
Working with Inventory
This chapter describes how to use the Inventory feature in Cisco Data Center Network Manager for LAN(DCNM-LAN).
Information About Inventory
The Inventory feature displays information about the components that comprise a selected managed device and power usage information for managed Cisco Nexus 7000 Series switches. In addition, it allows you to configure fundamental system parameters on virtual switches, such as the Cisco Nexus 1000V Series switch. For information about configuring virtual switches, see Chapter20, “Managing Virtual Devices”
System-message logging levels for the Inventory feature must meet or exceed Cisco DCNM requirements. During device discovery, Cisco DCNM detects inadequate logging levels and raises them to the minimum requirements. Cisco Nexus 7000 Series switches that run Cisco NX-OS Release 4.0 are an exception. For Cisco NX-OS Release 4.0, prior to device discovery, use the command-line interface to configure logging levels to meet or exceed Cisco DCNM requirements. For more information, see the Cisco DCNM Fundamentals Configuration Guide, Release 5.x .
This section includes the following topics:
Understanding Inventory
The Inventory feature displays summary and detailed information about the chassis, modules, fan trays, and power supplies for managed devices.
Understanding Power Usage
Cisco DCNM displays information about the power usage of managed Cisco Nexus 7000 Series switches, including an aggregation of the power usage for all managed Cisco Nexus 7000 Series switches, summary information for a specific device, and graphical information for a selected device.
You can configure Cisco DCNM to collect power usage statistics for up to six managed devices.
Module Pre-Provisioning
Note This feature is supported only on the Cisco Nexus 5000 Series switches.
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 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.
Supported Hardware
The pre-provisioning feature supports the following hardware:
- N2K-C2148T Fabric Extender 48x1G 4x10G Module
- N2K-C2232P Fabric Extender 32x10G Module
- N2K-C2248T Fabric Extender 48x1G 4x10G Module
- N51-M16EP Cisco 16x10-Gigabit Ethernet Expansion Module
- N51-M8E8FP Cisco 8-port 1/2/4/8G FC and 8 Port 10-Gigabit Ethernet Expansion Module
- N5K-M1008 Cisco 8-port Fiber Channel Expansion Module 8 x SFP
- N5K-M1060 Cisco 6-port Fiber Channel Expansion Module 6 x SFP
- N5K-M1404 Expansion Module 4 x 10GBase-T LAN, 4 x Fiber Channel
- N5K-M1600 Cisco 6-port 10-Gigabit Ethernet SFP Module 6 x SFP
Upgrades and Downgrades
When 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 supports pre-provisioning to another release that supports the feature including in-service software upgrades (ISSUs), 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.
Licensing Requirements for Inventory
The following table shows the licensing requirements for this feature:
Prerequisites
The Inventory feature has the following prerequisite (for a full list of feature-specific prerequisites, see the platform-specific documentation):
