ARP message management method based on network equipment

The invention provides an ARP message management method based on network equipment, and the method is to solve the problem of network attacks of ARP spoofing and ARP storm and the like. The method comprises the following steps: 1) judging whether a message is an ARP message; 2) judging whether network layer MAC and ARP MAC addresses are consistent; 3) judging whether a source IP address exists in an IP-MAC corresponding table; 4) judging whether the source IP address and a source MAC address exist in the IP-MAC corresponding table; 5) updating life periods of corresponding items of the source IP address and the source MAC address in the IP-MAC corresponding table; 6) adding the source IP address and the source MAC address to the IP-MAC corresponding table; 7) sending an IP conflict ARP message to a source device, and skipping to a step (15); 8) judging whether the message is an ARP request message or a response message; 9) searching whether searched IP information exists in the IP-MAC corresponding table; and 10) returning the ARP response data message.
