Why No Data Is Displayed on the AP Spectrum Chart?
Symptom
Why no data is displayed on the AP spectrum chart?
Possible Causes
If the spectrum analysis parameters are set incorrectly on devices, the devices fail to send spectrum packets to the eSight server.
Procedure
- Run the following commands on an AC of an earlier version than V200R006C10.
- Run the system-view command on the AC to enter the system view.
- Run the wlan command to enter the WLAN view.
- Run the spectrum-analysis ap-report-server ac port port-num command to specify the AC as the spectrum analysis server.
- Run the spectrum-analysis spectrogram-server ip-address ip-address port port-num command to specify the eSight server IP address to which spectrum packets are sent and the number of the port that receives spectrum packets from APs. The port number is 32181.
- Run the ap ap-id radio radio-id command to enter the radio view.
- Run the spectrum-analysis enable command to enable spectrum analysis for the APs.
- Run the spectrum-analysis spectrogram-server-report enable.
- Run the commit { all | ap ap-id } command to deliver the configurations to APs.
- Run the following commands on an AC of V200R006C10 or a later version.
- Run the system-view command on the AC to enter the system view.
- Run the wlan command to enter the WLAN view.
- Run the ap-system-profile name profile-name command to create an AP system profile and enter the profile view.
- Run the spectrum-analysis server ip-address ip-address port 32181 via-ac ac-port ac-port command to specify the eSight server IP address to which spectrum packets are sent and the number of the port that receives spectrum packets (UDP packets) from APs.
- Return to the WLAN view and run the ap-group name group-name and ap-system-profile profile-name command to bind the specified AP system profile to an AP group.
- Run the radio radio ID and spectrum-analysis enable commands to enter the radio view of the AP group and enable the spectrum analysis function on the specified radio.
- Return to the WLAN view and run the spectrum-report ap-name ap-name radio radio-id command to enable spectrum analysis for the APs.
