How Cisco DNA Center Works

Licensing Cisco DNA Center  1.3.1.0

Cisco DNA Center is a software solution that resides on the Cisco DNA Center appliance. The solution receives data in the form of streaming telemetry from every device (switch, router, access point, and wireless access controller) on the network. This data provides Cisco DNA Center with the real-time information it needs for the many functions it performs. For a device to be authorized to send data to Cisco DNA Center, that device must be included in your company’s Cisco DNA Software license subscription. These subscriptions are available for 3-, 5-, or 7-year terms. Cisco allows customers to purchase complete Cisco DNA Center functionality through a Cisco DNA Advantage license subscription or limited functionality through a Cisco DNA Essentials license subscription. Customers may also benefit from Cisco’s all-in-one software license, Cisco DNA Premier (formerly Cisco ONE). The Cisco DNA Premier license includes all Cisco DNA Advantage benefits plus the Cisco Identity Services Engine (ISE) for user identity policy and Cisco Stealthwatch for advanced security and Encrypted Traffic Analytics (ETA).

New features for Cisco DNA Center 1.3.1.0

Cisco DNA Center release 1.3.1.0 is a major upgrade with the inclusion of Cisco AI Network Analytics, uses machine learning to improve user experience and reduce troubleshooting. Group-based policy for configuring and managing secure groups and user policies, support for third party NPS and better security, are highlights of the many new features in this release.

The main deliverables of Cisco DNA Center 1.3.1.0 are: 

     Cisco AI Network Analytics: Cisco’s Intent-Based Networking just got smarter with Cisco AI Network Analytics, the cloud-based and on-premesis analytics engine that implements machine learning to improve user experience, and reduce time spent troubleshooting.  This is done through:

    Personalized baselining: Intelligently define personalized ”network normal” using unified global telemetry collected.

    Intelligent data analysis: Increase signal to noise, reduce false positives, and accurately identify trends and root causes.

    Accelerated remediation: Create automated resolution options for IT to act
on based on machine reasoning algorithms.

     Group-based policy is a major new capability in Cisco DNA Center for configuring, viewing and editing groups and policies. Through logical matrix interface, administrators can manage user access controls and segmentation using scalable groups, instead of IP address or VLANs. IT teams can create and manage “Secure Group Tags” (SGTs) from within Cisco DNA Center without having to open ISE (Cisco Identity Services Engine) or other network policy servers.

     AI-Analytics Security Advisories uses a Cisco Machine Reasoning Engine (MRE) to identify potential vulnerabilities in the network.  The Machine Reasoning Engine can be dynamically updated from the Machine Reasoning Knowledge Base to identify new security issues. Cisco DNA Center supported switches and routers can be scanned to identify software images that have a security advisory or security advisories. Identifying security advisories is a very time consuming task that can be automated through this advanced MRE technology.

     Support for third party network policy servers (NPS) has been a request from our users, and in release 1.3.1.0 it is here. Now Cisco DNA Center can integrate with your third party NPS, or Cisco ISE–the choice is yours. 

     Automation of Netflow and ETA configuration for Stealthwatch: Subscribers to Cisco Stealthwatch and ETA (Encrypted Traffic Analytics) have requested a simpler way to configure the Netflow settings that are required for telemetry transmission to the Stealwatch flow collectors. With release 1.3.1.0, IT administrators can configure Netflow and ETA on select switches and routers in their network. This feature saves customers hours of configuration.

Multiple ISE (Cisco Identity Services Engine) systems to a single DNA Center server. This feature allows multiple ISE systems to control policies and user access through a single Cisco DNA Center applicance.

Below is a more complete list of the major upgrades in Cisco DNA Center 1.3.1.0:

Table 2.             Cisco DNA Center new features for release 1.3.1.0:

Feature

Description and benefits

Analytics and Assurance

Cisco AI Network Analytics

Using AI and Machine Learning Cisco AI Network Analytics drives intelligence in the network, empowering administrators to accurately and effectively improve performance and issue resolution. We are taking network analytics to a new level where noise and false positives are significantly reduced when enabling customers to very accurately identify issues, trends, anomalies, and root causes.
Intelligent issue detection and analysis

  AI-driven personalized baselining: No two networks are the same. AI-driven technologies can learn the user trends, services, and application metrics that are specific to your network. Cisco DNA Assurance can then create a customized performance curve for analytical decisions. The AI-driven baseline for the performance parameters that are unique to your network is constantly adapted as your network grows and changes. From there, the AI-driven analytics engine (both on premises and in the Cisco cloud) can make accurate decisions for what is normal and what is not, based on this personalized baseline.
  AI-driven anomaly detection: Surfaces any deviation from our AI-created personalized baseline for this network. This allows Cisco DNA Center to make sense of all the network data. The system can accurately detect performance issues and ignore unusual, but harmless, network anomalies. This reduces noise while accurately identifying anomalies that have the greatest impact on your network. AI-driven predictive analytics and proactive insights allow users to anticipate and prevent failures. Here, the machine learning engine can predict increases in Wi-Fi interference, onboarding delays, office traffic load, etc. This is because, in IP networks, a problematic event is often proceeded by a benign event or series of events. By learning how series of events are correlated to one another, predictive analytics can help network administrators anticipate the unexpected.
  AI-driven accelerated remediation: Cisco AI Network Analytics provides accelerated remediation through machine learning, which identifies the most critical variables related to the root cause of a given problem. This helps users detect issues and vulnerabilities, perform complex root cause analysis, and execute corrective actions faster than ever. In coming releases, we will enable machine reasoning to execute the logical troubleshooting steps that an engineer would perform in order to resolve a problem. Both of these capabilities accelerate remediation making your team more precise in problem solving and more productive overall.

Extended Application Visibility to switch and Wireless Controllers

Application visibility allows Cisco DNA Assurance to monitor a user’s application usage, even from a switch or wireless controller. By using switches and wireless controllers, DNAC customers will have a complete view of application visibility across the campus network infrastructure.

Machine Reasoning (MRE)

The addition of an intelligent machine reasoning engine allows for further intelligence in Cisco DNA Center. Included is the ability to discover layer-2 spanning tree loops in your non-fabric (legacy L2) network. Additionally, the MRE will scan current switch inventory for outdated images, PSIRT alerts, and suspicious configurations. These abilities are outlined further below under “AI-Analytics Security Advisories.”

Automation

Device replacement and RMA workflows

Workfolw templates allows for the replacement (RMA) of a switch and router. Includes restoration of IOS, configuration and license. Also completes device replacement in operational systems such as Cisco ISE, Certificate Servers, and Cisco DNA Center inventory. Saves time and retains existing setup, licenses, and KPI trends.

PMP Bulk Update (Day 0)

Simplified workflows for updating device images and configurations via easy Day-0 steps.

Multiple ISE support

Ability to support multiple Cisco ISE systems to single Cisco DNA Center Appliance. Allows for multiple policy servers for applications such as employee network access vs guest network access.

Fog Director

Ability to manage and view Cisco industrial devices via connection with Cisco Fog Director. Fog Director delivers the capability to manage large-scale production deployments of IOx-enabled fog applications.

Security

Group-Based Policy

A major new capability in Cisco DNA Center for configuring, viewing and editing groups and policies. Through logical matrix interface, administrators can manage user access controls and segmentation using scalable groups, instead of IP address or VLANs. IT teams can create and manage “Secure Group Tags” (SGTs) from within Cisco DNA Center without having to open ISE (Cisco Identity Services Engine) or other network policy servers. Scale for group-based policy is as follows:

  Up to 4,000 scalable groups
  Up to 500 access contracts
  Up to 25,000 policies

3rd party NPS

Support for third party network policy servers (NPS) has been a request from our users, and in release 1.3.1.0 it is here. Now Cisco DNA Center can integrate with your third party NPS, or Cisco ISE – the choice is yours.

AI-Analytics Security Advisories

This feature uses the Machine Reasoning Engine (MRE) to identify potential vulnerabilities in the network.  The Machine Reasoning Engine can be dynamically updated from the Machine Reasoning Knowledge Base to identify new security issues. Cisco DNA Center supported switches and routers can be scanned to identify software images that have a security advisory or security advisories. Identifying security advisories is a very time consuming task that can be automated through the advanced MRE technology.

Netflow Automation for ETA support

In order for Stealthwatch to be able to detect malware in encrypted traffic (ETA) network devices must be configured to send Netflow and ETA to Cisco Stealthwatch. This new Cisco DNA Center feature allowsusers to configure select switches and routers to send data to Stealthwatch by using the Stealthwatch Security Analytics service. The service also allows users to configure select switches to send Netflow to Stealthwatch for devices that do not support ETA.

Product usage telemetry

Product usage telemetry provides valuable information about the status and capabilities of the Cisco DNA Center appliance. Cisco DNA Center is configured to automatically connect and transmit product usage data to Cisco. Product usage telemetry is used by Cisco to improve appliance lifecycle management for IT teams who have deployed Cisco DNA. Collecting this data helps the product teams serve customers better. This data and related insights enable Cisco to proactively identify potential issues, improve services and support, facilitate discussions to gather additional value from new and existing features, and assist IT teams with inventory report of license entitlement and upcoming renewals.

Table 7.             Cisco DNA Automation features and benefits

Feature

Description and benefits

Network discovery

Automatically discovers and maps network devices to a physical topology with detailed device-level data. The discovery function uses the following protocols and methods to retrieve device information, such as IP addresses, neighboring devices, and hosts connected to the device:

  Cisco Discovery Protocol
  Link Layer Discovery Protocol (LLDP) for endpoints
  IP Device Tracking (IPDT) and ARP entries for host discovery
  LLDP Media Endpoint Discovery (LLDP-MED) for discovering IP phones and some servers
  Simple Network Management Protocol (SNMP) versions 2 and 3

Network Information Database (NIDB)

Periodically scans the network to create a “single source of truth” for IT. This inventory includes all network devices, along with an abstraction for the entire enterprise network. It keeps an updated inventory of devices and software images on that device for version control. The NIDB provides data to applications (such as SWIM, and EasyQoS) so that the correct device and image version are used. It allows applications to be device independent, so configuration differences between devices aren’t a problem.

Meraki discovery and integration

Provides for the discovery of all Meraki devices on the network and integrates them into the Cisco DNA Center dashboard. It provides for a single pane of glass for both Cisco and Meraki devices.

Network design and profile-based management

Allows you to manage your network in a hierarchical fashion by letting you add areas and buildings on a geospatial map. You can start by defining your sites, then add buildings to sites, and finally add floors with detailed floor plans to the buildings. Cisco DNA Center lets the user define profiles, which consist of common network settings such as device credentials, DHCP, DNS server, AAA server, IP address pool, etc., Wireless settings such as SSIDs and RF profiles can be created globally and customized at site levels. These profiles form the basis for network automation.

Network Plug and Play (PnP)

Zero-touch provisioning for new device installation. Allows off-the-shelf Cisco devices to be provisioned simply by connecting them to the network. Cisco Network PnP provides a highly secure, scalable, seamless, and unified zero-touch-deployment experience for customers across Cisco's entire enterprise network portfolio of wired and wireless devices. Deploy new devices in minutes, and without onsite support visits. Eliminate repetitive tasks and eliminate staging. Network PnP reduces the burden on enterprises by greatly simplifying the deployment process for new devices, which can significantly lower Operating Expenditures (OpEx) as well. For more details, refer to the data sheet for the Network Plug and Play application.

https://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Plug-and-Play/solution/guidexml/b_pnp-solution-guide.html

Software Image Management (SWIM)

Manages software upgrades and controls the consistency of image versions and configurations across your network. Speeds and simplifies the deployment of new software images and patches. Pre- and post-checks help ensure no adverse effects from an upgrade. This is an easy to way to build a central repository of software images and apply them to devices. Administrators can mark software images as golden for a device family, allowing them to upgrade devices to the software image and patch versions that are in compliance with the golden versions defined in the repository.

  Golden images: Intent-based network upgrades allow for image standardization, much desired by network administrators
  Pre- and post-checks allow network administrators more control over and visibility into network upgrades
  Patches are supported in Cisco DNA Center from intent to pre- and post-checks in the same way that we manage regular images

ROMMon support for SWIM

The SWIM ROMMon upgrade feature optimizes already scheduled downtime by allowing users to join ROMMon upgrades with regular upgrades. The ROMMon feature in SWIM eases the task of upgrading ROMMon images on supported Cisco devices.

SMU patching

Provides patching for Software Maintenance Upgrade (SMU) recommendations and reduces the effort required to manually search for, identify, and analyze SMUs that are needed for a device. Cisco DNA Center automatically provides SMU management for multiple Cisco IOS® XR platforms and releases. Automates the patching process and allows most bug fixes to be patched with minimal network disruption.

Branch deployment automation

Simplified workflows for physical and virtual branch automation; day-0 router/NFV design. Onboard WAN devices and services via easy steps:

1. Configure network settings, service provider, and IP pools

2. Design a router or virtual profile

3. Assign to sites and provision network devices

Enterprise Network Functions Virtualization (ENFV) automation

Facilitates branch virtualization on any hardware device, Cisco or third-party. Saves time in setting up network virtual services. Supports existing branch migration without hardware upgrade. This feature includes full NFV management.

Wireless automation

Intent-based workflows for simplified wireless deployment and automation

  Network profiles: A container of wireless properties that can represent single or multiple sites
  Simplified guest and SSID creation
  Advanced RF support for wireless networks
  A single workflow to enable flex or centralized wireless deployment
  PnP provisioning for APs
  IP ACL support
  Access and access control policy for SD-Access Wireless only

Device tagging

An administrator can tag network devices in order to associate devices that share a common attribute. For example, you can create a tag and use it to group devices based upon a platform ID, Cisco IOS release, or location. Allows for grouping of devices based on specialized needs.

Policy creation

Allows the creation of policies based on business intent for a particular part of the network. Users can be assigned policies for the services that they consume, and these policies follow them throughout the network. Policies are translated by Cisco DNA Center into network-specific and device-specific configurations that can be adjusted dynamically based on network conditions. Of foundational importance for intent-based networking, policies define the business intent that is desired and allow the network to guarantee services.

Application policy creation

Allows policies to be assigned to applications based on business relevance. These applications can then be attached to sites (locations) where the policy should be applied. This feature allows business-critical applications to have greater QoS priority in the sites where their use is relevant. It is important for mission-critical applications such as machine-to-machine control in manufacturing or life-saving devices in healthcare, as well as for business-critical applications such as video in customer experience centers or voice in support sites.

Feature

Description and benefits

Northbound REST APIs

The Cisco DNA Center platform supports Representational State Transfer (REST) APIs at the northbound layer for programmability. The Cisco DNA Center API provides support for the following features:

  Discovery, device inventory, network topology
  SWIM, Plug and Play (PnP)
  Template programmer, command runner
  Assurance: Site, device, and client health monitoring, path trace
  NFV provisioning

IT Service Management (ITSM) integration

The ITSM integration minimizes the need for handoffs, deduplicates issues, and optimizes processes for proactive insights and faster remediation. Out-of-the-box integration exists with ServiceNow. The generic APIs exposed by the Cisco DNA Center platform enable partners and developers to integrate with any ITSM system.

IP Address Management (IPAM) integration

This integration allows for a seamless import of IP pools for Cisco DNA Center workflows from external IPAM systems and the synchronization of IP pool and subpool usage information between the two systems. Out-of-the-box integration exists with Infoblox and Bluecat. The Cisco DNA Center platform provides generic APIs to integrate with any IPAM system.

Events and notifications

The Cisco DNA Center platform webhooks allow third-party applications to receive notifications and listen to any events detected by Cisco DNA Assurance, Automation, and other task-based operational workflows.

Multivendor SDK

The Cisco DNA Center Multivendor Device Pack SDK allows partners to add support for managing third-party devices directly via Cisco DNA Center.

Cisco DNA Center 1.3.1.0 appliance: scale and hardware specifications

This new second generation (Gen2) of Cisco DNA Center appliance is available in three form factors and comes with the Cisco DNA Center image preloaded on it and ready for installation. Notice that the entry level Gen2 appliance (DN2-HW-APL) has the same size, performance, and capacity specifications as the first generation (Gen1) Cisco DNA Center Appliance (DN1-HW-APL). The reason for the change is to put all three Gen2 appliances on the newer Cisco “M5 Series” UCS. If you currently have a Gen1 appliance (based on the “M4 Series” UCS), there is no need to upgrade, and there is no advantage to upgrading since both Gen1 and Gen2 entry appliances are based on 44 core processing units. Customers looking for greater performance, in order to support more capacity, are advised to upgrade to the 56 core “mid-size” Gen2 appliance (DN2-HW-APL-L) or the 112 core “large” Gen2 appliance (DN2-HW-APL-XL). Table 9 captures the scale information for Cisco DNA Center Release 1.3.1.0.
