Usage Scenario

After rate limit on ARP Miss messages is enabled, you can set maximum rate and rate limit duration of ARP Miss messages. If the number of ARP Miss messages triggered by IP packets in the rate limit duration exceeds the limit, the device discards the ARP Miss packets triggering the excess ARP Miss messages.
