Abstract

The present disclosure provides a method, device, device, and machine-readable storage medium for managing a security entry. The method includes: after allocating an IP address to a DHCP client, determining the IP address and MAC address of the DHCP client; Send a first message, where the first message carries the IP address and the MAC address; the first message is used to make the DHCP relay record the correspondence between the IP address and the MAC address in the security entry, so that the The DHCP relay filters the received authentication message according to the security entry; after the DHCP client goes offline, determines the IP address and MAC address of the DHCP client; sends a second message to the DHCP relay, the The second message carries the IP address and the MAC address; the second message is used to make the DHCP relay delete the correspondence between the IP address and the MAC address from the security table entry. Through the technical solution of the present disclosure, the authentication server is prevented from processing a large number of illegal authentication messages, and the processing resources of the authentication server are saved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a management method, device, equipment and machine-readable storage medium for security entries. Background technique [0002] The DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) can adopt the client / server mode, and the DHCP server (Server) dynamically allocates an IP address for the DHCP client (Client). Moreover, when the DHCP client and the DHCP server are in different physical network segments, the DHCP client can also communicate with the DHCP server through a DHCP relay (Relay). [0003] The DHCP client sends a DHCP-DISCOVER (discovery) message in broadcast mode. After the DHCP relay agent receives the DHCP-DISCOVER message, it unicasts it to the specified DHCP server. After the DHCP server receives the DHCP-DISCOVER message, it selects the idle IP address, and send a DHCP-OFFER (offer) message to the DHCP client throug...
