Cisco ThousandEyes is a solution that provides end-to-end visibility into network performance and application experience, particularly in campus environments that rely on external SaaS applications and cloud services. It helps organizations monitor service delivery outcomes, even when they do not control the networks involved. Key benefits include reducing fault isolation time from days to minutes, enabling evidence-based escalations with service providers, and optimizing application performance across various networks.

Cisco ThousandEyes integrates seamlessly with Catalyst 9300 and 9400 Series switches through a Cisco DNA Advantage subscription. This integration allows organizations to run network and web tests at 5-minute intervals, providing insights into external services from within the campus LAN. It enhances visibility into application performance, employee experience, and network metrics, facilitating better management of both internal and external services.

To effectively use Cisco ThousandEyes, you need to have Catalyst 9300, 9300L, or 9400 Series switches with a Cisco DNA Advantage subscription. Additionally, you should check your Cisco Smart Software Manager for your ThousandEyes entitlement and follow the provided instructions for deployment. For optimal performance, ensure that your switches are equipped with SSD storage, especially if you plan to run more complex tests that require additional resources.
