Operating Modes
- Local Mode: Default mode for client servicing, utilizing CAPWAP tunnels for centralized management. Handles both management and data traffic, known as central switching.
- FlexConnect Mode: Allows local data switching, enabling continued operation during controller disconnection.
- Monitor Mode: Acts as a dedicated sensor for: Intrusion detection systems (IDS). Rogue AP detection. Location-based services (LBS).
- Sniffer Mode: Captures and forwards wireless packets for remote analysis using tools like Wireshark or AiroPeek NX. Includes metadata like timestamps, signal strength, and packet size.
  
  Note
  
  The mode requires the receiving server to be on the same VLAN as the controller management VLAN.
- Site Survey Mode: Enables RF parameter configuration for site survey investigations, simplifying network planning and installation.
- SDA/Fabric Mode: Supports Software-Defined Access (SD-Access) for advanced segmentation and policy enforcement.
External Interfaces
- USB Port: Supports additional device connectivity for enhanced flexibility.
- Dual Ethernet Ports: Provides redundancy for uninterrupted connectivity in high-reliability environments.
Software Features

With the new Wi-Fi 7 APs, Cisco now has one AP portfolio that can be used either with the Meraki cloud native network or Catalyst on-premise controller-based deployments. With the introduction of the one AP portfolio, it is essential to have a single product ID (PID) at manufacturing, to simplify logistics or operations. This AP model is designed for global use under a single PID. To verify approval and to identify the regulatory domain that corresponds to a particular country, see https://www.cisco.com/c/dam/assets/prod/wireless/wireless-compliance-tool/index.html. Regulatory approvals are continually updated as they are obtained.
