Cisco Network Assurance Engine Medium Virtual Appliance - Term License (5 Years) - CNAEL-VAPLK9-5Y-M

• Out-of-Band Management Access
  In out-of-band management access (OOB), the Cisco NAE appliance can access the ACI fabric on the out-of-band network.
• In-Band Management Access
  In in-band management access, the Cisco NAE appliance will use the leaf switches for in-band access to the ACI fabric.
• Network Address Translation (NAT) Deployment
  Cisco NAE can access ACI fabric deployed across the NAT boundary. In this topology, Cisco NAE communicates with Cisco APIC through NAT.

The Cisco Network Assurance Engine (NAE) software provides operators with a new approach to manage SDN-based data centers confidently. The Cisco NAE software is built on a comprehensive formal model of the network, combined with deep domain knowledge of networking. The Cisco NAE software provides operations teams with continuous and proactive network verification and intent assurance.
Business drivers such as cloud, mobile, and digitization trends are demanding more from modern data centers, rapidly increasing their scale, rate of change, and complexity. With the Cisco Application Centric Infrastructure (ACI) and other SDN technologies, network infrastructures have evolved to provide programmable interfaces, automation, agility, and virtualization. However, operational tools still center on traditional approaches, such as probe tools, packet sniffers, and the command line interface (CLI) to reason about the network. These are inherently reactive-after-the-fact, manual, and rely on the tribal knowledge of a handful of experts to reasonably reconstruct a network state.
The Cisco NAE software takes the intent from the controller as a logical policy, as well as configurations and the data plane (infra) state from each switch device, to build a network-wide model of the underlay, overlay, and virtualization layers.
