    Hi @KleinStreisend,

    To setup RSTP  on GS 1910, you need to select the Protocol Version on your first screenshot(Spanning Tree > Bridge Setting).
    Then go to CIST Ports to enable STP for the ports which you would like to apply RSTP.

    CIST is "Common and Internal Spanning Tree" and MSTI is "MST Instance"(Multiple Spanning Tree Instance).
    Both of them are the region of MSTP(Multiple Spanning Tree Protocol), CIST is the region of whole MSTP and MSTI is Spanning tree running within MST region for multiple VLANs.
    And the MST region is known as a group of switches to form up multiple spanning tree instances.

    MSTI mapping is to setup which VLANs mapping to which MSTI.(Multiple VLANs can mapping to the same MSTI and one VLAN ONLY mapping to one MSTI). Notice: RSTP don't need to set this setting.

    MSTI priorities is to inspect the current STP MSTI bridge instance priority configurations. The lower numeric values have better priority. Notice: RSTP don't need to set this setting.
