1-4in the non-permanent static ARP entry, the device adds the interface receiving the ARP reply to thenon-permanent static ARP entry. Then the entry can be used for forwarding IP packets.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 short staticARP entry for it. To allow communication with a device through a specific interface in a specificVLAN and using a fixed IP-to-MAC mapping, configure a long static ARP entry for it.Configuring ARPConfiguring a Static ARP EntryA static ARP entry is effective when the device works normally. However, when a VLAN or VLANinterface to which a static ARP entry corresponds is deleted, the entry, if permanent, will be deleted, andif non-permanent and resolved, will become unresolved.Follow these steps to configure a static ARP entry:To do… Use the command… RemarksEnter system view system-view —Configure a permanentstatic ARP entryarp static ip-address mac-addressvlan-id interface-typeinterface-numberRequiredNo permanent static ARP entryis configured by default.Configure anon-permanent static ARPentryarp static ip-address mac-addressRequiredNo non-permanent static ARPentry is configured by default.The vlan-id argument must be the ID of an existing VLAN which corresponds to the ARP entries.
