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 Chapter 4 "Managing Virtual Switches."

This section includes the following topics:

Understanding Inventory

Understanding Power Usage

Module Pre-Provisioning

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:

Product
License Requirement

Cisco DCNM

Inventory requires no license. Any feature not included in a license package is bundled with Cisco DCNM and is provided at no charge to you. For information about obtaining and installing a Cisco DCNM LAN Enterprise license, see the Cisco DCNM Installation and Licensing Guide, Release 5.x.

Cisco NX-OS

Inventory requires no license. Any feature not included in a license package is bundled with the Cisco NX-OS system images and is provided at no extra charge to you. For an explanation of the Cisco NX-OS licensing scheme for your platform, see the licensing guide for your platform.


Prerequisites

The Inventory feature has the following prerequisite (for a full list of feature-specific prerequisites, see the platform-specific documentation):

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 Guide, Release 5.x.

Platform Support

The following platforms support this feature but may implement it differently. For platform-specific information, including guidelines and limitations, system defaults, and configuration limits, see the corresponding documentation.
