Cisco Nexus Dashboard Material Controller (NDFC) is the brand new, power-packed, feature-rich service (previously Knowledge Middle Community Supervisor or DCNM) solely out there on the Cisco Nexus Dashboard (ND). NDFC embraces a Kubernetes-based microservices structure. With the introduction of NDFC Launch 12, customers get a constant expertise throughout NDFC and different companies hosted on Nexus Dashboard together with Insights and Orchestrator.
NDFC offers complete lifecycle administration, configuration, and automation for Cisco NX-OS, IOS-XE, IOS-XR, in addition to non-Cisco gadgets, for a myriad of deployments. Not like DCNM, NDFC now not wants customers to pick a mode for LAN, SAN, or IP Material for Media (IPFM) on the time of set up. As a substitute, NDFC makes use of a runtime function enabler. This functionality selectively allows or disables totally different options and related function units or personas. Like Material Controller (LAN), SAN Controller, and Material Discovery. Customers can now allow the options they need at runtime which permits their clusters to scale higher.
How can I begin utilizing NDFC?
To start with NDFC, you want a Nexus Dashboard cluster first. ND is deployed as a cluster of grasp and employee nodes in a digital kind issue (digital ND or vND) or a bodily kind issue (Bodily ND or pND). The sort in addition to the variety of nodes required in a given ND cluster internet hosting NDFC, usually relies on the variety of managed/monitored switches, in addition to the persona-specific options (LAN, SAN, IPFM, Material Discovery). It’s doable to cohost NDFC with different companies like Insights and Orchestrator in the identical ND cluster. Cisco has put collectively an easy-to-use capability planning device to calculate the variety of ND nodes required based mostly in your necessities and scale.
How can I begin constructing my Material with NDFC?
NDFCs out-of-box templates permit for VXLAN EVPN deployment of Nexus or Catalyst 9k switches, Legacy or Traditional 2-Tier, 3-Tier routed materials, and Multi-Website deployments based mostly on printed Cisco greatest practices. As well as, customers can create new templates and customise current ones based mostly on their particular surroundings. This makes the answer extraordinarily versatile to make use of. For instance, the Simple material template is constructed for simple deployment of a VXLAN EVPN underlay in a brownfield or greenfield material. Varied mixtures are supported together with choices for numbered/unnumbered IP addressing for hyperlinks, Inside Gateway Protocols like OSPF and IS-IS, replication modes like multicast (BiDir and ASM), and ingress replication, IPv4 versus IPv6 underlay, and so forth. With minimal inputs (simply the material title and ASN by default), a totally practical VXLAN EVPN material will be introduced up in a couple of minutes.
With the novel Material Builder, NDFC allows a centralized configuration push throughout your complete material, with periodic monitoring of configuration compliance and the well being of the materials. Any deviation from the intent outlined in NDFC shall be flagged and an alarm shall be generated. This permits the administrator to not solely view the deviation but in addition deliver the gadgets again in sync thereby sustaining central management.
All configuration operations associated to switches, hyperlinks, interfaces, overlays, RMA, credential administration, discovery, vPC pairing, L4-7 companies provisioning, and many others. can be found with a easy click on on the suitable object of curiosity, be it a swap, material, hyperlink or overlay. Varied workflows throughout the controller embed context-sensitive menus with granular RBAC.
NDFC makes use of a 3-step continuum for configuration administration and automation of all community entities: (a) Save (b) Preview (c) Deploy. As soon as the switches are found and managed by NDFC, customers should outline swap roles. As a community system can have varied duties, varied swap roles exist resembling Leaf, Backbone, Border leaf, Border Backbone, Border Gateway, Border Gateway Backbone, Core, Edge and many others.
NDFC additionally has a one-click vPC pairing choice to arrange vPC domains. NDFC makes use of the outlined material settings, and the found topology to construct configurations for all of the switches, based mostly on Cisco greatest practices. “Save” section is what that is termed as. At this level, NDFC is able to push the required configurations to the material.
A side-by-side diff between the user-defined intent and operating configurations within the switches is displayed for person preview (Preview section). As soon as the person validates the adjustments, the configurations will be deployed at a material/swap/interface stage (Deploy section). Voila, this completes the setup of a full Knowledge Middle material. All through the life cycle of the material, incremental configuration adjustments will be simply pushed with acceptable rollback choices. Whereas all of the operations described above are doable by way of the GUI, all of them are additionally out there by way of REST-APIs to attain large-scale automation.
My Material is now UP. What NEXT?
Whereas NDFC is nice for provisioning, it will also be used extensively post-deployment for picture upgrades, patching, license administration, host visibility with VMs, Containers, Endpoint tracker, IPAM integration, scheduling periodic programmable reviews, monitoring alarms and occasions at a swap and material stage, RMA of a defective swap, monitoring the essential statistics of every swap like CPU, reminiscence, temperature, site visitors, and many others. With Material Controller, the topology view lets you see the real-time operational and configuration standing of the switches in every material together with the protocol state of the hyperlinks.
