ARP Configuration Commands 
arp check enable 
Syntax 
arp check enable 
undo arp check enable 
View 
System view 
Parameters 
None 
Description 
Use the arp check enable command to enable the ARP entry checking function on a switch. 
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. 
Examples 
# Disable the ARP entry checking function. 
<Sysname> system-view 
System View: return to User View with Ctrl+Z. 
[Sysname] undo arp check enable
