[guiabreufranca]

Hi,

In the past week a have faced a flapping issue im my network on my switches.
I have heterogeneous models of switch and brands ion my site.
So, what i am doing is correcting the STP settings on all my switches L2.

in this case, i dont know if my STP is ENABLE, because on GUI in options: Device > MSTP > Device Setup  is showing me the STP is not enable.
and CLI is showing this when i do the commando "display stp":
