This variable controls the BPDU Guard operation of the entire
switch (globally). To control the BPDU Guard function of each port use
hmIfaceStpBpduGuardEnable.
If BPDU guard functionality are global enabled (hmSysStpBPDUGuardEnable=enable(1)),
and BPDU guard are enabled per port (hmIfaceStpBpduGuardEnable=enable(1)) and (R)STP are globally enabled
and an BPDU are received on the port, then hmIfaceStpBpduGuardStatus is set to true(1) for this port and
IfAdminStatus is set to down(2) for this port.
Variable hmIfaceStpBpduGuardStatus can be reset (to their original values (=false)) with switching
BPDU guard functionality globally off (hmSysStpBPDUGuardEnable=disable(2)).
IfAdminStatus can be again reset to to their original values up() only manually.
The default value of hmSysStpBPDUGuardEnable is disable(2).
