If a large number of Identity packets for 802.1X authentication are sent to the CPU of a switch, the CPU usage is high and other services are affected. To prevent this problem, run the access-user dot1x-identity speed-limit command to configure the rate limit of Identity packets for 802.1X authentication to be sent to the CPU, so that the switch discards excess Identity packets.
The system view is displayed.
The rate limit of Identity packets for 802.1X authentication to be sent to the CPU is configured.
By default, the maximum of Identity packets for 802.1X authentication can be sent to the CPU every second depends on the device.
