Example: Configuring a short static ARP entry

As shown in Figure 4, hosts are connected to Device B. Device B is connected to Device A through interface GigabitEthernet 1/0/2.

To ensure secure communications between Device A and Device B, configure a short static ARP entry for Device A on Device B.

# Configure an IP address for GigabitEthernet 1/0/2.

<DeviceB> system-view
[DeviceB] interface gigabitethernet 1/0/2
[DeviceB-GigabitEthernet1/0/2] ip address 192.168.1.2 24
[DeviceB-GigabitEthernet1/0/2] quit

# Configure a short static ARP entry that has IP address 192.168.1.1 and MAC address 00e0-fc01-001f.

[DeviceB] arp static 192.168.1.1 00e0-fc01-001f

# Verify that Device B has a short static ARP entry for Device A

[DeviceB] display arp static
