Reviewers frequently integrate Cisco Catalyst Center for comprehensive network management, indicating a preference for a centralized platform that works seamlessly with their wireless infrastructure. This integration likely streamlines operations and provides a unified view across various network components.

Cisco Identity Services Engine (ISE) is utilized by some reviewers to enhance security and access control within their networks. Its integration with wireless controllers suggests a focus on robust authentication and policy enforcement for connected devices.

Reviewers also incorporate Cisco Secure Firewall Management Center to manage their network security, highlighting the importance of integrated firewall control. This suggests a strategy to secure the network edge and internal segments alongside wireless access.

Cisco ThousandEyes is used by a segment of reviewers for network visibility and performance monitoring. This indicates a need for advanced insights into application and network performance, extending beyond the local wireless infrastructure to broader network paths.

Reviewers frequently highlight the Cisco Catalyst 9800 Series Wireless Controllers for their capacity to centralize and simplify wireless network management. This functionality allows organizations to easily discover, configure, and monitor access points across numerous sites from a single interface, significantly reducing operational overhead. The use of tags and templates further streamlines configuration and deployment, making the process efficient and less prone to errors.

The controllers are valued for their ability to support large-scale wireless deployments and accommodate significant growth in connected devices and access points. Organizations leverage these controllers to manage extensive networks, ranging from dozens to thousands of access points across multiple campuses or data centers. This scalability addresses the business need for a wireless infrastructure that can expand without compromising performance or stability.

Reviewers indicate that the Cisco Catalyst 9800 Series Wireless Controllers play a key role in modernizing existing wireless infrastructure. The controllers offer increased flexibility in configuration and simplify the deployment process for new access points, contributing to a more agile and efficient network. This modernization supports critical operations by providing a stable and reliable wireless environment for various professional tools and services.

The controllers are utilized to implement robust network segmentation and redundancy strategies, which are critical for maintaining high availability and security. Organizations deploy dedicated pairs of controllers and configure them for load balancing and active-active N+1 setups. This ensures continuous wireless service and the ability to manage different traffic types, such as guest traffic, securely and efficiently.

The graphical user interface (GUI) was a primary area of concern for 5 of 12 reviewers, who found its performance to be slow, even on newer hardware. Reviewers also noted a lack of consistent filtering options across all displays and suggested that the overall organization of the GUI could be improved for better clarity and ease of use.

Software stability presented challenges for 3 of 12 reviewers, who reported frequent bugs that often required code upgrades or system reloads to rectify. Some users also experienced difficulties with software distribution, particularly when integrating with other Cisco tools like Catalyst Center.

The initial configuration and setup process was identified by 2 of 12 reviewers as an area needing improvement. Reviewers suggested that some simple configuration tasks have become less intuitive or harder to locate, indicating a potential benefit from a more guided setup experience.

The way data is presented and filtered within tables was a significant drawback for 2 of 12 reviewers, especially when monitoring APs or clients. Reviewers found that tables often truncated lists to only a hundred items, making it difficult to sort or filter comprehensive data sets effectively, a capability that was reportedly more robust in previous AireOS versions.
