Problems solved by technology

[0004] In the prior art, for the offline detection method of a newly authenticated MAC, the source hit mark of the MAC is cleared in a detection cycle, and the MAC is deleted if the source hit mark of the MAC is not detected in the next detection cycle, like this, It takes 2 detection cycles to let the user go offline, which takes a long time

Abstract

This application provides a method and switch for setting the offline detection time of MAC address authentication. The processing unit receives and forwards the data message sent by the chip through the chip channel and its receiving port identification; if the processing unit based on the source MAC address of the data message is in If no matching authentication information entry is found in the MAC authentication list, the data packet is authenticated. After the data packet passes the authentication, a virtual port is assigned to the physical port indicated by the receiving port identifier of the data packet. Record the authentication information entry of the source MAC address, and set the aging time of the authentication information entry as the MAC address offline detection cycle; the processing unit uses the allocated virtual port as the output port to generate a forwarding entry and synchronize it to the forwarding chip; The forwarding entry record is recorded in the hardware forwarding table. It implements an offline detection cycle to delete the authentication table information of the source MAC, shortens the user offline cycle, and improves the user offline efficiency.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a method and a switch for setting a MAC address authentication offline detection time. Background technique [0002] Physical address (Media Access Control or Medium Access Control, MAC) address authentication is an authentication method based on port and MAC address to control the user's network access authority, without installing client software. After the device detects a data packet from a user on the port on which MAC address authentication is enabled for the first time, it starts to authenticate the user's MAC address. If the user is successfully authenticated, it is allowed to access network resources through the port. [0003] After the MAC address authentication offline detection function of the port is enabled on the device, if the device does not receive any message from the online user on the port within the interval of an offline detection tim...
