process INFO

[Yurii_001]

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.

 What is the objective of the process INFO?

Why INFO used so many cpu time?

Can you share the sanitized configuration? it looks like something related to syslogging (info-center)...what software versions are those switches currently running on?

[Yurii_001]

I found source of problem. It was absence this command in my configuration: undo info-center logfile enable
