Hello everyone.Thank you for all your help.
I have been experiencing the following symptoms for several weeks.
When I check the traffic information on the APs registered with vSZ-H, there are times when the values for traffic and number of connections are missing, as shown in the attached image.
As far as we have confirmed on site, there is no interruption in the same time, streaming, etc., and there is no problem with communication.
The first time I discovered this coincided with the timing of the firmware upgrade, so I thought that might be the cause, but I have no proof.
The current environment is as follows
Controller version 18.104.22.168.1563Controller plane version 22.214.171.124.1540AP firmware 126.96.36.199.2069 (R650)
Please let me know if you have similar symptoms or know of any possible causes.
