Upgrading or Downgrading to a New Release
Auto-Negotiation Disable
Beginning with Cisco NX-OS Release 5.0(3)N2(1), you can disable auto-negotiation on a switch port.
This feature allows you to connect devices that do not support auto-negotiation (for example, certain
DWDM multiplexers) to a Cisco Nexus 5000 Series switch.
Licensing
The Cisco NX-OS licensing feature allows you to access premium features on the device after you install
the appropriate license for that feature. Any feature not included in a license package is bundled with the
Cisco NX-OS software and is provided to you at no extra charge.
You must purchase and install a license for each device.
Note You can enable most features without installing a license. The Cisco NX-OS software provides a grace
period for most features during which time you can try out a feature before purchasing its license. The
Layer 3 features do not have a grace period and require an installed Layer 3 Base license to use the
routing features.
Beginning with Cisco NX-OS Release 5.0(3)N2(1), the FCoE NPV license (FCOE_NPV_PKG) is
available to use the FCoE NPV feature.
For more information on licensing, see the Cisco NX-OS Licensing Guide.
Data Center Network Manager Release 5.2 Support
Cisco DCNM is advanced management software that provides comprehensive life cycle management for
the data center LAN and SAN.
Cisco DCNM Release 5.2 combines Cisco Fabric Manager, which previously managed SANs, and Cisco
DCNM, which previously managed only LANs, into a unified product that can manage a converged data
center fabric. As a part of the product merger in Cisco DCNM Release 5.2, the name Cisco DCNM for
SAN replaces the name Cisco Fabric Manager. The name Cisco Fabric Manager still applies to Cisco
Fabric Manager Release 5.0(x) and all earlier versions.
Cisco DCNM Release 5.2 supports the Cisco Nexus product family including the Cisco Nexus 5000
Series, Cisco MDS 9000 product family, Catalyst 6500 Series, and the Cisco UCS product family.
For information about new DCNM features for the Cisco Nexus 5000 Series switch, see the Cisco DCNM
Release Notes, Release 5.2. For Cisco Nexus 5000 Series and DCNM compatibility information, see the
Cisco DCNM Release Compatibility Matrix.
