1.1.1 arp check enable
Syntax
arp check enable
undo arp check enable
View
System view
Parameter
None
Description
Use the arp check enable command to enable ARP entry check, inhibiting the device from learning multicast MAC addresses.
Use the undo arp check enable command to disable the function, allowing the device to learn multicast MAC addresses.
By default, ARP entry check is enabled.
Example
# Configure the switch to learn multicast MAC addresses.

1.1.2 arp max-learning-num
Syntax
arp max-learning-num number
undo arp max-learning-num
View
VLAN interface view
Parameter
number: Maximum number of dynamic ARP entries that the interface can learn. This argument ranges from 1 to 2,560.
Description
Use the arp max-learning-num command to set the maximum number of dynamic ARP entries that an interface can learn.
Use the undo arp max-learning-num command to restore the default.
By default, an interface can learn up to 2,560 dynamic ARP entries.
Example
# Allow VLAN-interface 40 to learn up to 500 dynamic ARP entries.

1.1.3 arp static
Syntax
arp static ip-address mac-address [ vlan-id interface-type interface-number ]
undo arp ip-address
View
System view
Parameter
ip-address: IP address in an ARP entry.
mac-address: MAC address in an ARP entry, in the format H-H-H.
vlan-id: ID of a VLAN to which a static ARP entry belongs to, in the range 1 to 4094.
interface-type interface-number: Type and number of a port.
Description
Use the arp static command to configure a static ARP entry in the ARP mapping table.
Use the undo arp command to remove an ARP entry.
Note that:
l A static ARP entry is valid as long as the device works normally. However, when the VLAN or VLAN interface corresponding to an ARP entry is deleted, the entry is also deleted.
l When you configure an ARP entry with the vlan-id argument, the VLAN ID you specify must be the ID of an existing VLAN with VLAN interface already configured, and the Ethernet port following the argument must belong to the VLAN.
Related command: reset arp, display arp.
Example
# Configure a static ARP entry, with the IP address being 202.38.10.2, the corresponding MAC address being 000f-e201-0000, and the outbound port being Ethernet1/0/3 in VLAN 10.
