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
