Clearing ARP entries from the ARP table might cause communication failures. Make sure the entries to be
cleared do not affect current communications.

Network requirements
As shown in Figure 3, hosts are connected to the switch, which is connected to the router through
interface Ten-GigabitEthernet 1/0/1 in VLAN 10.
To ensure secure communications between the router and switch, configure a static ARP entry for the
router on the switch.
