Large enterprise networks require centralized platforms for device management, configuration consistency, software lifecycle management, wireless monitoring, compliance, troubleshooting, and operational visibility. As network environments evolve toward intent-based networking, software-defined access, automation, and analytics-driven operations, traditional infrastructure-management platforms may no longer provide the capabilities required to manage increasingly dynamic environments.
Toyota Motor North America (TMNA) initiated a network-management modernization program to transition from Cisco Prime Infrastructure (PI) to Cisco DNA Center, establishing a centralized platform for network automation, wireless assurance, Radio Resource Management (RRM) analytics, software-image management, configuration management, and Software-Defined Access (SDA) operations.
The project included migration and reconstruction of wireless configurations, RF profiles, network templates, device inventories, and access-point placement information from Prime Infrastructure into the DNA Center operational model. Existing Prime capabilities involving compliance monitoring, software image management, and device configuration backups were also transitioned to corresponding DNA Center functions.
For SDA-enabled locations, DNA Center became the centralized platform for fabric provisioning, network segmentation, Scalable Group Tag (SGT) policy integration, and assurance.
As a Network Consultant with Tata Consultancy Services, Srinivas Marka contributed to existing-environment assessment, migration architecture, device onboarding, wireless-management transition, template development, RF and Assurance validation, SDA integration, troubleshooting, and operational handover.
The working project scope encompassed approximately 5,000+ managed network devices, 2,000+ wireless access points, 10+ major TMNA sites, 50+ standardized configuration/templates and profiles, and 20,000+ connected users and endpoints. More than 1,000 migration and operational validation checks were performed.
The resulting architecture established DNA Center as a more centralized, automation-oriented, analytics-driven platform for managing TMNA's evolving enterprise network infrastructure.
