Parameters

ip-address: Specifies the IP address in an ARP entry.

mac-address: Specifies the MAC address in an ARP entry, in the format H-H-H.

vlan-id: Specifies the ID of a VLAN to which a static ARP entry belongs, in the range of 1 to 4094.

interface-type interface-number: Specifies the interface type and interface number.

vpn-instance vpn-instance-name: Specifies the MPLS L3VPN for a static ARP entry. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. Without this option, the static ARP entry belongs to the public network.

Description

Use arp static to configure a static ARP entry in the ARP mapping table.

Use undo arp to remove an ARP entry.

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 long, will be deleted, and if short and resolved, will become unresolved.

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

If both the vlan-id and ip-address arguments are specified, the IP address of the VLAN interface corresponding to the vlan-id argument must be in the same network segment as the IP address specified by the ip-address argument.

Related commands: reset arp and display arp.

Examples
