Parameter None

Description Use the arp check enable command to enable ARP entry check, preventing the device from learning multicast MAC addresses. With this function enabled, the device 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.

Use the undo arp check enable command to disable the function, allowing the device to learn multicast MAC addresses. After the ARP entry check is disabled, the device can learn the ARP entry with a multicast MAC address, and you can also configure such a static ARP entry on the device.

By default, ARP entry check is enabled.

Example # Enable ARP entry check.
