Use the arp rate-limit enable command to enable the ARP packet rate limit function on the port, that is, 

to limit the rate of ARP packets passing through the port. If a rate (the maximum ARP packet rate is 15 

pps by default) is specified, exceeding ARP packets will be discarded.  

Use the undo arp rate-limit enable command to disable the ARP packet rate limit function on the port.  

By default, the ARP packet rate limit function is disabled, that is, ARP packet rate is not limited on a port.

Use the arp restricted-forwarding enable command to enable ARP restricted forwarding so that the 

legal ARP requests received from the specified VLAN are forwarded through configured trusted ports

through trusted ports if the MAC address table contains no such destination MAC addresses. 

Use the undo arp restricted-forwarding enable command to disable ARP restricted forwarding.  

By default, ARP restricted forwarding is disabled.
