Impact on the System
If ARP packets are suppressed, the transmit rate of ARP packets exceeds the configured rate limit. As a result, some ARP packets are discarded and traffic cannot be forwarded normally.
If ARP Miss messages are suppressed, the transmit rate of ARP Miss messages exceeds the configured rate limit. As a result, some ARP Miss messages are discarded and ARP Request messages cannot be triggered. Therefore, traffic cannot be forwarded normally.
