Cisco Nexus Hyperfabric enables customers easily to design, deploy, and scale any number of data center fabrics located anywhere. Delivered as a fabric-as-a-service solution, it reinvents and simplifies every step of IT operations, ensuring repeatable and predictable outcomes.

Note

Software version 20250320 had its end of support on October 15, 2025. If any devices in a fabric are running this version, in the Cisco Nexus Hyperfabric GUI, you will see a banner with text similar to this example:

Fabric1 device software approaching targeted end of support

You have less than one month to upgrade your devices to a newer version go to software management.

Fabric1 is the name of your fabric. You must upgrade the software of the devices to a supported version.

Feature

Description

Removal of the "classic" fabric mode

The "Classic" fabric mode has been removed. There is now only one fabric mode, which does not have a special label in the GUI. Nexus Hyperfabric automatically migrates all classic fabrics to the one (and only) fabric mode.

BGP import and export policy local preference rule type

Local preference indicates the preferred path for traffic to reach a specific network. A path with a higher local preference value is preferred over others.

For more information, see Cisco Nexus Hyperfabric — Configure BGP.
