Catalyst 9800-CL
In today's hybrid world, your wireless network can't be tied to a physical location. You need the flexibility to manage connectivity across distributed offices, private data centers, and public clouds with consistent performance and security. The Cisco Catalyst 9800-CL Wireless Controller is the answer, delivering enterprise-class Wi-Fi management as a virtual appliance, free from the constraints of hardware.
Built on the resilient and programmable Cisco IOS XE operating system, the 9800-CL brings Cisco's legendary RF excellence into the cloud. It allows you to deploy a powerful, feature-rich wireless controller exactly where you need it—on VMware, KVM, Hyper-V, or in AWS, Azure, and Google Cloud. Experience unparalleled agility, operational continuity, and intelligent security for your entire wireless infrastructure.
The Cisco Catalyst 9800-CL isn't just a controller in the cloud; it's a paradigm shift in wireless network management. It's designed around three core pillars: Always On, Secure, and Deployed Anywhere. This means your network benefits from seamless software updates and stateful switchover for zero downtime, a multi-layered security architecture that protects against threats in encrypted traffic, and the freedom to deploy consistently on any hypervisor or public cloud platform.
With support for up to 6,000 access points and 64,000 clients, the 9800-CL scales effortlessly from a small branch office to a large enterprise campus. Its open, programmable architecture with model-driven telemetry and APIs allows for deep automation, giving your IT team the tools to manage, monitor, and troubleshoot with unprecedented efficiency. It's the intelligent, flexible foundation for a modern, business-critical wireless network.

Q: What is the Cisco Catalyst 9800-CL?
A: The Cisco 9800-CL is a virtual wireless controller. Instead of a physical hardware appliance, it runs as software on a hypervisor (like VMware ESXi, KVM) in your private data center or as an instance in a public cloud (like AWS, Azure, GCP). It provides the same enterprise-class features, security, and scalability as a physical controller but with greater deployment flexibility.
Q: What are the main advantages of a virtual controller over a physical one?
A: The key advantages are deployment flexibility, resource optimization, and operational agility. You can deploy it on existing server hardware or cloud infrastructure, avoiding hardware lifecycle management. It's ideal for organizations with a cloud-first strategy or those wanting to consolidate resources in their data center. For a full comparison based on your needs, our Nexus ITX specialists can provide a detailed consultation.
Q: How does the 9800-CL ensure the network is 'always on'?
A: It uses several high-availability features. In-Service Software Upgrade (ISSU) and hot patching allow for updates and security patches without any network downtime. Stateful Switchover (SSO) with N+1 redundancy ensures that if a primary controller fails, a backup takes over instantly and seamlessly, preserving active client sessions.
Q: Is it difficult to migrate from an older Cisco controller (like AireOS) to the 9800-CL?
A: Cisco provides tools to simplify migration, but the process requires careful planning to ensure a smooth transition. Nexus ITX specializes in these migrations. Our experts can manage the entire process, from planning and configuration translation to deployment and validation, ensuring zero disruption to your users.
Q: How do I determine the right size (vCPUs, RAM) for my 9800-CL deployment?
A: The required virtual resources depend on the scale of your network—specifically, the number of access points and clients you need to support. The 9800-CL has profiles from 'Ultra-low' to 'Large'. Our solution architects at Nexus ITX can help you analyze your current and future needs to recommend the most cost-effective and performant configuration.
Q: Can the 9800-CL be managed by Cisco Catalyst Center?
A: Yes, absolutely. The Catalyst 9800-CL is fully integrated with Cisco Catalyst Center (formerly Cisco DNA Center), which provides a centralized management dashboard for policy automation, network assurance, and advanced analytics for your entire wired and wireless network.
Q: Does Nexus ITX provide deployment and support for the 9800-CL in the UAE?
A: Yes. As a Dubai-based Cisco partner, we provide end-to-end services for the Catalyst 9800-CL across the UAE and the Middle East. This includes initial consultation, solution design, deployment, migration from legacy systems, and ongoing managed support. Contact us to discuss your specific project requirements.
