Hello,
I think I might have misconfigured something.
I have a switch giving me those messages.
the model is an eight port
GS1920-8HP
with firmware
V4.70(ABKZ.5)

NO stp: STP topology changes
IN system: CPU utilization is over 100 and keep 5 seconds, driver count = 115.
IN system: CPU utilization is over 100 and keep 5 seconds, driver count = 224.
DE interface: Port 7 - link up 100M/F
DE interface: Port 7 - link down
DE interface: Port 7 - link up 1G/F
DE interface: Port 7 - link down
DE interface: Port 7 - link up 1G/F
DE interface: Port 7 - link down
DE interface: Port 7 - link up 1G/F

Is this common for a semi default switch?
Thanks.

    Any loop between this switch and another one?

    @Hoygen83,
    May I know if the issue still persists? Based on the logs, there is a topology change occurs, more likely there is a ring topology in the environment which may cause a loop if there is a misconfiguration. The easy way is to check the SW port LED in the front panel and see if a port is blinking fast. Or you may enable the loop guard feature for access ports [PC] and enable spanning-tree for connected switches.
