If ARP strict learning is not enabled on an S series switch, except S1700, and a VLANIF interface on the switch is in a large broadcast domain, the switch learns ARP packets from any devices and generates ARP entries. The switch may need to maintain a large number of ARP entries. To address this problem, run the arp learning strict command to enable ARP strict learning.
