 STP Configuration. 

Select the Spanning Tree Admin Mode Disable or Enable radio button.

This specifies whether spanning tree operation is enabled on the switch.

Select a Force Protocol Version radio button.

This specifies the Force Protocol Version parameter for the switch. The options are IEEE 
802.1d, IEEE 802.1w, and IEEE 802.1s.

This specifies whether spanning tree BPDUs should be forwarded while spanning-tree is 
disabled on the switch.

This specifies whether the BPDU guard feature is enabled. The STP BPDU guard allows 
a network administrator to enforce the STP domain borders and keep the active topology 
consistent and predictable. The switches behind the edge ports with STP BPDU guard 
enabled are not able to influence the overall STP topology. At the reception of BPDUs, 
the BPDU guard operation disables the port that is configured with this option and 
transitions the port into a disabled state. This would lead to an administrative disable of 
the port.

Select the BPDU Filter Disable or Enable radio button.

This specifies whether the BPDU Filter feature is enabled. STP BPDU filtering applies to
