Abstract: A booting mode configuration method executable by an electronic device is disclosed. It is determined whether a configured booting mode is detected. If the configured booting mode is detected, a booting program corresponding to the configured booting mode is performed. If the configured booting mode is not detected, it is determined whether an access point is detected for connection. When the access point is detected, a satellite mode of the electronic device is configured and a booting program corresponding to the satellite mode is performed. When the access point is not detected and a wired connection is enabled, it is determined whether a PADO packet or a DHCP Offer packet is received to configure the electronic device as the satellite mode or a base mode, and a booting program corresponding to the satellite mode or the base mode is performed.

Abstract: A network device records IP addresses and MAC addresses of a plurality of CPEs to form an address mapping table, sends first ARP request packets to the plurality of CPEs according to the IP addresses in the address mapping table, and receives first ARP response packets. The network device compares the MAC addresses in the first ARP response packets with the corresponding MAC addresses in the address mapping table to identify an unusual MAC address. The network device generates a plurality of IP addresses randomly, sends second ARP request packets according to the plurality of IP addresses, and receives second ARP response packets. In response to a MAC address in the second ARP response packets being same with the unusual MAC address, the network device blocks packets transmission corresponding to the unusual MAC address.
