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

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.
