Hello, friends!
In network, switch 1920-8g has very high cpu usage. Over 70-80% used by process INFO. There are 2 end users connected and 2 trunk in switch. I replaced switch with another one 1920-8g PoE+ (65w), (configuration the same). Everything remains as it was.
Why INFO used so many cpu time?
