Description 
Use the arp check enable command to enable ARP entry check. With this function enabled, the AP 
cannot learn any ARP entry with a multicast MAC address, and you cannot configure such a static ARP 
entry with a multicast MAC address on the AR; otherwise, the system displays error messages. 
Use the undo arp check enable command to disable the function. After ARP entry check is disabled, 
the AP can learn the ARP entry with a multicast MAC address, and you can also configure such a static 
ARP entry on the AP. 
By default, ARP entry check is enabled.
