Abstract
A method, an apparatus, a device, and a system for generating a Dynamic Host Configuration Protocol snooping (DHCP) Snooping binding table. The method includes: constructing a request packet for obtaining information about a DHCP client, and sending the request packet to a DHCP server; receiving a response packet corresponding to the request packet, and extracting the information about the client from the response packet, where the information about the client includes the client's Internet Protocol (IP) address and Media Access Control (MAC) address; and obtaining the client's virtual local area network (VLAN) number and ingress port number through the MAC address, and generating the DHCP Snooping binding table. The technical solutions solve the problem that traffic of some clients is lost due to a lack of a DHCP Snooping binding table of these clients in a process of enabling DHCP Snooping.
