FAQs

Q: What licensing is required for the C9800-80-K9?
A: The controller itself requires no license to boot. However, each access point connecting to the controller requires a Cisco DNA subscription license—either DNA Essentials or DNA Advantage tier—assigned to the AP for full functionality.

Q: Does the C9800-80-K9 support high availability?
A: Yes, the Catalyst 9800-80 supports stateful switchover (SSO) high availability mode. It can be deployed in redundant pairs for seamless failover, and supports In-Service Software Upgrade (ISSU) for zero-downtime upgrades.

Q: What types of access points can this controller manage?
A: The C9800-80-K9 manages Cisco Aironet and Catalyst access points, including Wi-Fi 6 (802.11ax) and Wi-Fi 6E models. It supports both local and FlexConnect deployment modes and integrates with Cisco DNA Center for centralized management.

Q: Can I expand the uplink capacity beyond the built-in ports?
A: Yes. The C9800-80 includes one Ethernet Port Adapter (EPA) slot that accepts hot-swappable uplink modules supporting 10GE, 40GE, or 100GE QSFP transceivers, allowing flexible high-speed connectivity to the wired network.

Q: What deployment scenarios is the C9800-80-K9 best suited for?
A: This controller is ideal for large enterprise campuses, data centers, high-density venues, and distributed branch deployments requiring centralized control, advanced security, and scalability for thousands of access points and tens of thousands of concurrent clients.
