SLEs (Service Level Expectations) help monitor and ensure Wi-Fi network performance.

Visible SLEs:

Capacity:

B: Capacity SLE monitors the network's ability to handle the number of connected clients and their bandwidth requirements.

Throughput:

D: Throughput SLE measures the data transfer rates, ensuring that the network meets the expected performance levels.

Other Options:

Switch Health: Relates to wired network performance, not Wi-Fi.

Application Health: Generally focuses on application performance, not specifically Wi-Fi.

Conclusion:

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.

In the context of Mist management, "brownfield" switches refer to those that are already configured and deployed in a network, while "greenfield" switches are new and have no pre-existing configuration.

Mist supports the integration and management of both brownfield and greenfield switches within the same site. The crucial requirement is that all switches, regardless of their initial state, must be running a version of Junos that is supported by Mist.

This compatibility ensures that Mist can apply policies, configurations, and monitoring uniformly across all devices, facilitating a seamless management experience.
