Description
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
only, and the legal ARP responses are forwarded according to the MAC addresses in the packets, or
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.

Parameters
None
Description
Use the arp send-gratuitous enable vrrp command to enable the master switch of a VRRP backup
group to send gratuitous ARP packets periodically. Upon receiving the gratuitous ARP packets, hosts
on the network update their respective ARP tables. This can prevent other devices on the network from
using the same IP address as the VRRP backup group.
Use the undo arp send-gratuitous enable vrrp command to disable this function.
