Hi,
I am planning to implement STP in our network. I created a testing environment including 2 HPE 1920 and two unmanaged switches. STP is configured and working well. So if I connect additional cables between the two 1920s the root bridge keeps all its ports in forwarding stage and the second 1920 switches the ones unnecessary into a discarded state - that's how it should be. Unfortunately there are plenty of unmanaged switches under the desks, do they operate in an STP environment?
I thought in scenario 1 one of the 1920 would switch to a discarded state on one of the ports, where an unmanaged switch is connected to and in scenario 2 both 1920 would disable the ports with the unmanaged switches since there is a loop happening. I have tested my theory and no ports are disabled. Do I need to swap all unmanaged switches to managed one in order to achieve my goal?
Kind Regards
