The Cisco Nexus Fabric Manager (NFM) is a product designed to simplify fabric lifecycle management requirements for users requiring easier options than switch-by-switch offerings such as CLI and element managers. The NFM provides a simple point-n-click web-based user interface to a fabric-aware management engine that can build and manage fabrics based on simplified user requests. The NFM bears the heavy lifting of creating, installing, and maintaining proper fabric-wide switch configurations to deliver on these simplified requests. The NFM, being fabric-aware, also understands how the fabric should operate and can monitor and take actions within the fabric throughout its lifecycle to ensure optimal fabric operation. You can focus on workflows associated with delivering business-enabling applications and leave the complexity of building and managing the fabric to the NFM.
Behind the scenes, the NFM implements a self-managed VXLAN-based topology incorporating an EVPN control plane. This choice of technology ensures a future-proofed fabric delivering service for today and tomorrow’s requirements in an open manner.

The following are the known limitations for Cisco Nexus Fabric Manager:
· The NFM supports the configuration of border-leaf switches but does not support border-spine configurations.
· The maximum number of total switches within a supported fabric is 20. This number represents a combination of leaf and spine switches.
· The maximum number of host-facing interfaces within the fabric connected to devices such as physical servers, firewalls, and load balancers is 1000. For example, a dual-homed host would count as two host-facing attachments.
· The maximum number of discovered hosts is limited to 500.
· The maximum number of configurable broadcast domains is limited to 200.
· The Cisco Nexus 2000 Series of fabric extenders (FEX) is supported in a limited fashion. It must be manually connected to a Cisco Nexus 9000 Series leaf switch. At this point, their interfaces are shown within the Cisco Nexus Fabric Manager.
· The Cisco Unified Compute System B-Series (UCS) fabric interconnect module is discoverable by the NFM. However, any compute blades behind it are not represented within the NFM topology.
