Penjelasan :# interface number
# mengatur mode interface
# enable PORT SECURITY
# interface akan Membaca MAC-ADDRESS DI RUNN CONFIG
# MAXIMUM HANYA 1 MAC-ADDRESS YG diset / diizinkan di interface ini
# MEMBUAT DAMPAK SHUTDOWN, kepada PC NOT REGISTERED
# MENGAKTIKAN interface ini
# exit / back
# melihat running config
