Step Command Remarks
3. Configure a multiport ARP
entry.
arp multiport ip-address mac-address
vlan-id [ vpn-instance
vpn-instance-name ]
By default, no multiport ARP
entries are configured.
Setting the maximum number of dynamic ARP
entries for a device
A device can dynamically learn ARP entries. To prevent a device from holding too many ARP entries, you
can set the maximum number of dynamic ARP entries that the device can learn. When the maximum
number is reached, the device stops learning ARP entries.
If you set a value lower than the number of existing dynamic ARP entries, the device does not remove the
existing entries unless they are aged out. The device also stops learning ARP entries until the number of
dynamic ARP entries is below the configured value.

number
By default, a device can learn a maximum of
16384 dynamic ARP entries.
To disable the device from learning dynamic
ARP entries, set the number to 0.
Setting the maximum number of dynamic ARP
entries for an interface
An interface can dynamically learn ARP entries. To prevent an interface from holding too many ARP
entries, you can set the maximum number of dynamic ARP entries that the interface can learn. When the
maximum number is reached, the interface stops learning ARP entries.
The Layer-2 interface can learn an ARP entry only when both its maximum number and the VLAN
interface's maximum number are not reached.
