The arp static command configures a static Address Resolution Protocol (ARP) entry.
The undo arp static command deletes a static ARP entry.
By default, no static ARP entry is configured.

| Parameter | Description | Value |
|---|---|---|
| ip-address |
Specifies the IP address in a static ARP entry. |
The value is in dotted decimal notation. |
| mac-address |
Specifies the MAC address in a static ARP entry. |
The value is a 12-digit hexadecimal number, in the format of H-H-H. Each H is 4 digits. If an H contains fewer than 4 digits, the left-most digits are padded with zeros. For example, e0 is displayed as 00e0. |
| vid vlan-id |
Specifies the outer VLAN ID corresponding to a static ARP entry. |
The value is an integer ranging from 1 to 4094. |
| interface interface-name |
Specifies the name of the outbound interface of static ARP packets. |
- |
| interface interface-type interface-number |
Specifies the outbound interface of static ARP packets. |
- |
| cevid cevid |
Specifies the inner VLAN ID corresponding to a static ARP entry. |
The value is an integer ranging from 1 to 4094. |
| vpn-instance vpn-instance-name |
Specifies the VPN instance name of a static ARP entry. |
The value is a string of 1 to 31 characters. |
| all |
Deletes all static ARP entries. |
- |
Usage Scenario
The arp static command usage is as follows:
Implementation Procedure
Create a static ARP entry. If the static ARP entry already exists, the system updates the entry.
Configuration Impact
After a static ARP entry is configured, the ARP entry cannot be dynamically learned.
Precautions
When configuring static ARP on a QinQ or dot1q VLAN tag termination sub-interface, you must specify an outbound interface. Otherwise, traffic cannot be forwarded. In this case, the QinQ or dot1q VLAN tag termination sub-interface does not learn the outbound interface of packets.
