Access: read-only
Description: Counter of L3 Control protocol frames foward to cpu.
What is cmEthernetTrafficPortStatsAclFwd2Cpu?
This counter records the number of Layer 3 control protocol frames on this port that were forwarded to the device's CPU for processing rather than switched in hardware. An admin watches this because an unusually high rate of CPU-forwarded control frames can load the control-plane CPU and, in extreme cases, threaten device stability. For example, if a device starts experiencing high CPU utilization, the admin would check whether cmEthernetTrafficPortStatsAclFwd2Cpu on a particular port has spiked, indicating a flood of control-plane traffic being punted to the CPU.
