Hi Younglak,
BPDU guard prevents loops by moving a nontrunking port into an errdisable state when a BPDU is received on that port.
In Aruba OS switches this concept is implemented using the bpdu-protection command. BPDU protection disables the specific port or ports if the port(s) receives STP BPDUs.
Command:
ArubaOS(config)# spanning-tree <port-number(s)> bpdu-protection.
If you just want to supress the BPDUs on that port instead of disabling the port use the BPDU filter command instead:
ArubaOS(config)# spanning-tree <port-number(s)> bpdu-filter
BPDU filter: Stop a specific port or ports from transmitting BPDUs,
receiving BPDUs, and assume a continuous fowarding
state.
