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.

# Set the maximum number of dynamic ARP entries that can be learned on 
VLAN-interface 40 to 500.

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: Interface type and interface number.

vpn-instance vpn-instance-name: Name of a VLAN instance, a case-sensitive 
string of 1 to 31 characters.

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:

■

A static ARP entry is effective when the device works normally. However, when 
the VLAN or VLAN interface to which an ARP entry corresponds is deleted, the 
entry, if permanent, will be deleted, and if non-permanent and resolved, will 
become unresolved.

■

The vlan-id argument is used to specify the corresponding VLAN of an ARP 
entry and must be the ID of an existing VLAN. In addition, the Ethernet 
interfaces following the argument must belong to that VLAN. The VLAN 
interface of the VLAN must have been created.

■

Before using the command with the vpn-instance keyword to configure a 
permanent static ARP entry, you need to create a VPN instance and bind it to 
the VLAN interface.
