Abstract
An Address Resolution Protocol (ARP) packet processing method, a communication system and a device are disclosed. The method includes: receiving an ARP packet, and judging the type of the ARP packet; when the ARP packet is an ARP request, responding to the ARP request if an entry corresponding to the ARP request is found in a local ARP table; and when the ARP packet is an ARP response, reporting the ARP response if an entry corresponding to the ARP response is found in the local ARP table and a reporting parameter in the entry indicates permission of reporting; or discarding the ARP response if no entry corresponding to the ARP response is found in the ARP table.
