bpdu-guard vs stp-protect ruckus switch

unknown

Can anyone explain what is the difference between stp-protect and bpdu-guard?
as far as I know stp-protect can be enabled on the end station port to prevent port from initiate or participate on STP topology, also bpdu-guard can be configured on the end station port to disable the port if a BPDU is received on that port. So I don't see the difference between two of them.
Thank you

The BPDU guard, an enhancement to STP, removes a node that reflects BPDUs back in the network. It enforces the STP domain borders and keeps the active topology predictable by not allowing any network devices behind a BPDU guard-enabled port to participate in STP.

You can enable STP Protection on a per-port basis.

To prevent an end station from initiating or participating in STP topology changes, enter the following command at the Interface level of the CLI.

device#(config) interface ethernet 2
device#(config-if-e1000-2)#stp-protect

This command causes the port to drop STP BPDUs sent from the device on the other end of the link.

Enter the no form of the command to disable STP protection on the port.

So STP Protect drops BPDUs coming in and err-disables the port.
BPDU guard Will err-disable ports where BPDUs are reflected back into the switch.....meaning there is a loop and it will open up the loop.
