PERFORMANCE SUMMARY

This table provides the following details specific to the radios:

• Number of clients—The number of client devices connected to a specific Access Point.

• Channel—Channel number at which the access point’s radio is broadcasting the signal.

  Note	Number of channels will be 1, 2 and 4 for 20MHz, 40MHz and 80 MHz respectively.

• Configured Rate—The default minimum and maximum data rates of the access point.

• Usage Traffic—The amount of data that has transferred between access point and the client device.

• Throughput—This represents the amount of data that can be transferred from the access point to the client device.

• Transmit Power—The logarithmic power level at which the access point is broadcasting the signal.

• Noise—Noise refers to any energy interference that degrades the quality of a wireless signal. Noise can affect everything from radio transmissions to network speeds.

• Channel Utilization—Level of traffic including data and interference over the channel that is assigned on the AP. Interference includes both Wi-Fi and non Wi-Fi signals. High utilization of channel, for example above 50%, suggests high level of interference including noise from nearby APs/clients/rogues on the same channel which results in poor client performance.

• Interference—RF interference involves unwanted, interference of RF signals that disrupt normal wireless operations, that creates potential network latency and poor client performance. Interfering RF signals includes both Wi-Fi and non-Wi-Fi signals.

• Traffic—Shows the data traffic in 2.4GHz and 5GHz radio.

• Admin Status—Status of the Radios for 2.4 GHz and 5 GHz.

• Interferer Detection—Status of Interferer detection for 2.4GHz and 5GHz radios.

    • Emergencies (0)

    • Alerts (1)

    • Critical (2)

    • Errors (3)

    • Warnings (4)

    • Notifications (5) (Default)

    • Informational (6)

    • Debugging (7)

    Messages with a severity equal to or less than the set level are sent to the syslog server.

• LOGGING – Option to Enable/disable the Logging for individual AP. By default, the logging is Disabled. If the logging is enabled, the syslog messages will be sent to the configured Syslog server else the messages will not be sent to the Syslog Server.

  Note

  This configuration is available for all APs (Mesh Extenders, Primary AP, Primary Capable APs). Syslog Server IP configured for each AP can be same/different. By default, Syslog Server IP would be configured as broadcast (255.255.255.255). The Level will be set to Notifications. To capture the Primary AP logs: Configure the Syslog Server details under Advanced > Logging > Add Syslog Server. Set the Logging level under Advanced > Logging > Log Syslog Level.
