Description: Set the maximum number of unresolvable packets that the device can receive from a device in five seconds.
What is hh3cARPSourceSuppressionLimit?
This value, constrained between 2 and 1024, sets the maximum number of unresolvable ARP packets an HH3C device will accept from a single source within a five-second window before further packets from that source get suppressed. An administrator tunes this threshold to balance protection against ARP floods with tolerance for legitimate hosts that might briefly generate a burst of ARP traffic. With the default value of 10, the device allows up to 10 unresolved ARP packets from a given source every five seconds before suppressing that source further.
