Hi @W.Pamungkas ,

Any L3 interface will allow it.  Run this command to see.

clearing the arp entries from the interface would trigger any issue ? 

any active tcp session to drop or existing ips should get abandoned with no arp entries ?

Hi @sparab ,

Clearing the ARP entries should not trigger any issue or cause sessions to drop.  It should only cause the NGFW to send ARP requests again.  It does that when the ARP timers runs out for each entry anyway.

Thanks,
