Configure edge port and enable BPDU protection:
[HW-SW3] stp bpdu- protection // SW3 open global BPDU protection
[HW-SW3] interface GigabitEthernet 0/0/1 // configuration g0 / 0/1 port
[HW-SW3-GigabitEthernet0 / 0 /1] stp edged -port disable // do not open edge port
[HW-SW3-GigabitEthernet0 / 0 /1] int g 0/0/3 // configuration g0 / 0/3 port
[HW-SW3-GigabitEthernet0 / 0 /3] stp edged- port disable // do not open edge port
[HW-SW3] stp edged- port default // Enable global edge ports
*** // Before turning on the need to protect the global bpdu trunk link port is not open edge
[HW-SW3]display cu | i stp
stp edged-port default
