z 

Usually ARP dynamically resolves IP addresses to MAC addresses, without manual intervention. 

z 

To allow communication with a device using a fixed IP-to-MAC mapping, configure a 

non-permanent static ARP entry for it. To allow communication with a device through a specific 

interface and using a fixed IP-to-MAC mapping, configure a permanent static ARP entry for it. 

 

A static ARP entry is effective when the device works normally. However, when a VLAN or VLAN 

interface to which a static ARP entry corresponds is deleted, the entry, if permanent, will be deleted, 

and if non-permanent and resolved, will become unresolved. 

Follow these steps to configure a static ARP entry: 

Enter system view 

— 

Configure a permanent 
static ARP entry  

arp static ip-address 
mac-address vlan-id 
interface-type interface-number 
[ vpn-instance 
vpn-instance-name ] 

Required 

No permanent static ARP entry is 
configured by default. 

Configure a 
non-permanent static 
ARP entry  

arp static ip-address 
mac-address [ vpn-instance 
vpn-instance-name ] 

Required 

No non-permanent static ARP entry is 
configured by default. 

 

z 

The vlan-id argument must be the ID of an existing VLAN which corresponds to the ARP entries. In 

addition, the Ethernet interface following the argument must belong to that VLAN. A VLAN 

interface must be created for the VLAN. 

z 

The IP address of the VLAN interface corresponding to the vlan-id argument must belong to the 

same network segment as the IP address specified by the ip-address argument. 

 

Follow these steps to set the maximum number of dynamic ARP entries that an interface can learn: 

Enter system view 

— 

Enter Ethernet interface view 

interface interface-type 
interface-number
