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 entrywith a multicast MAC address, and you can also configure such a static ARP entry onthe switch.By default, the ARP entry checking function is enabled.Examples# Disable the ARP entry checking function. system-viewSystem View: return to User View with Ctrl+Z.[Sysname] undo arp check enable1.1.3 arp detection enableSyntaxarp detection enableundo arp detection enableViewVLAN viewParametersNoneDescriptionUse the arp detection enable command to enable the ARP attack detection functionon all ports in the specified VLAN. When receiving an ARP packet from a port in thisVLAN, the switch will check the source IP address, source MAC address, number of thereceiving port, and the VLAN of the port. If the mapping of the source IP address andsource MAC address is not included in the DHCP snooping entries or IP static bindingentries, or the number of the receiving port and the VLAN of the port do not match theDHCP snooping entries or IP static binding entries, the ARP packet will be discarded.Use the undo arp detection enable command to disable the ARP attack detectionfunction on all ports in the specified VLAN.
