Release 12.1.3b became available.

Product Overview

Cisco Nexus Dashboard Fabric Controller (NDFC) is the comprehensive management solution for all NX-OS deployments spanning LAN, SAN, and IP Fabric for Media (IPFM) networks in data centers powered by Cisco. Cisco NDFC also supports devices such as IOS XE switches, IOS XR routers, and third-party devices. Being a multi-fabric controller, Cisco NDFC manages multiple deployment models like VXLAN EVPN, Classic 3-Tier, FabricPath, and Routed Fabrics for LAN while providing ready-to-use control, management, monitoring, and automation capabilities. In addition, when enabled as a SAN Controller, NDFC automates Cisco Multilayer Director Switches (MDS) and Cisco Nexus Family infrastructure in NX-OS mode with a focus on storage-specific features and analytics.

This document describes the features, bugs, and limitations for Cisco NDFC release 12.1.3b.

Cisco NDFC focuses on control and management for three primary market segments:

●    LAN including VXLAN EVPN, VXLAN EVPN Multi-Site, Classic Ethernet, and External fabrics supporting Cisco Nexus switches with NX-OS, additional support for IOS XR, IOS XE, and adjacent host, compute, virtual machine, and container management systems.

●    SAN for Cisco MDS and Cisco Nexus switches with NX-OS, including support for integration with storage arrays and additionally host, and Virtual Machine systems.

●    Media control for Multicast video production networks using Cisco Nexus switches operating as standalone NX-OS, with additional integrations for 3rd party media control systems.

Cisco NDFC and Nexus Dashboard

Cisco NDFC is available as an application running exclusively with Cisco Nexus Dashboard Virtual or Physical Appliance.

Virtual Nexus Dashboard deployment with OVA is also referred to as virtual Nexus Dashboard (vND) deployment, while the deployment of Nexus Dashboard on physical appliance (Service Engine) is known as physical Nexus Dashboard (pND) deployment. To deploy Nexus Dashboard based on your requirement, refer to Cisco Nexus Dashboard Deployment Guide.

The following table shows the compatible versions for Nexus Dashboard and services.
