1.2.2 Configuring the Maximum Number of ARP Entries for a VLAN Interface

Follow these steps to set the maximum number of dynamic ARP entries that a VLAN
interface can learn:
Enter system view
Enter VLAN interface view
Set the maximum number of
dynamic ARP entries that a
VLAN interface can learn

1.2.3 Setting Aging Time for Dynamic ARP Entries

After dynamic ARP entries expire, the system will delete them from the ARP mapping
table. You can adjust the aging time for dynamic ARP entries according to the actual
network condition.
Follow these steps to set aging time for dynamic ARP entries:
Enter system view
Set aging time for
dynamic ARP entries

1.2.4 Enabling the ARP Entry Check

The ARP entry check can control the device to learn multicast MAC addresses. With
the ARP entry check 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.
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.
