Before updating ARP entries, clear ARP entries on the device so that the device will relearn the entries.
NOTICE:
After ARP entries are cleared, mappings between IP addresses and MAC addresses are deleted. As a result, users may not access specified nodes. Exercise caution when you clear ARP entries.
