ARP Entry Limiting

ARP Entry Limiting

The ARP entry limiting function controls the number of ARP entries that a gateway interface can learn. By default, the number of ARP entries that an interface can dynamically learn is the same as the default number of ARP entries supported by the device. After the ARP entry limiting function is deployed, if the number of ARP entries that a specified interface dynamically learned reaches the maximum, the interface cannot learn any ARP entry. This prevents ARP entries from being exhausted when a host connecting to this interface initiates ARP attacks.
