Syntax
arp check enable
undo arp check enable
View

Parameters
None
Description
Use the arp check enable command to enable the ARP entry checking function.
Use the undo arp check enable command to disable the ARP entry checking function.
With the ARP entry checking function enabled, the switch cannot learn any ARP entry
with a multicast MAC address. Configuring such a static ARP entry is not allowed either;
otherwise, the system prompts error information.
After the ARP entry checking function is disabled, the switch can learn the ARP entry
with a multicast MAC address, and you can also configure such a static ARP entry on
the switch.
By default, the ARP entry checking function is enabled.
