After user-level rate limiting is enabled, the switch discards the excess packets if the rate of packets from the same source MAC address exceeds the rate limit within a specified period of time. To check the information about discarded packets, you can run the cpu-defend host-car drop-packet monitor disable command to enable monitoring for packets discarded due to user-level rate limiting.
The system view is displayed.
Monitoring for packets discarded due to user-level rate limiting is enabled.
By default, monitoring for packets discarded due to user-level rate limiting is enabled.
The rate limit for sending packets that are discarded due to user-level rate limiting to the CPU is set.
By default, the CIR and CBS for sending packets that are discarded due to user-level rate limiting to the CPU are 64 kbit/s and 12032 bytes, respectively.
