Description: Counter of L3 Control protocol frames foward to cpu.
What is cmEthernetTrafficPortHistoryAclFwd2Cpu?
This counter records the number of Layer 3 control protocol frames on this port forwarded to the CPU during the archived historical interval rather than switched in hardware. A historical spike helps the admin correlate a past CPU-utilization event with a burst of control-plane traffic being punted to software on this specific port. For example, if the device logged high CPU usage yesterday afternoon, the admin would check that interval's cmEthernetTrafficPortHistoryAclFwd2Cpu on each port to find which one was flooding the CPU with control traffic.
