Packet Capture: This feature allows for detailed inspection of traffic at the packet level. Capturing packets can help identify issues with authentication protocols, such as misconfigured settings or failures in the authentication exchange process.
Client Events: Monitoring client events provides insights into the client's authentication attempts, including successes and failures. This data helps in pinpointing where in the process the failure occurs, whether at the client, access point, or authentication server.

The Simple Network Management Protocol (SNMP) is used by Mist to monitor non-Juniper switches. SNMP is a widely adopted protocol for network management, enabling the collection and organization of information about managed devices on IP networks.

Real-time Assessment: Juniper Mist's Radio Resource Management (RRM) builds the channel plan based on real-time network assessments. It dynamically adjusts to changing conditions in the RF environment, ensuring optimal performance by continuously monitoring factors such as interference, client distribution, and usage patterns. Automatic Tuning: RRM tuning happens automatically. Mist AI leverages reinforcement learning to continually optimize RF settings without manual intervention, adjusting channels, power levels, and other parameters in real-time to maintain optimal network performance.
