# Configure DHCP.
[SwitchA] dhcp enable
[SwitchA] dhcp server ip-pool 1

2. Configure Switch B:
<SwitchB> system-view
[SwitchB] interface ten-gigabitethernet 1/0/1
[SwitchB-Ten-GigabitEthernet1/0/1] port link-mode route
[SwitchB-Ten-GigabitEthernet1/0/1] ip address dhcp-alloc
[SwitchB-Ten-GigabitEthernet1/0/1] quit
Verifying the configuration
# Display authorized ARP entry information on Switch A.
[SwitchA] display arp all
Type: S-Static D-Dynamic O-Openflow M-Multiport I-Invalid
IP Address MAC Address VLAN Interface Aging Type
10.1.1.2 0012-3f86-e94c N/A XGE1/0/1 20 D
The output shows that IP address 10.1.1.2 has been assigned to Switch B.
Switch B must use the IP address and MAC address in the authorized ARP entry to communicate with
Switch A. Otherwise, the communication fails. Thus user validity is ensured.
Configuration example (on a DHCP relay agent)
Network requirements
As shown in Figure 113 , configure authorized ARP on Ten-GigabitEthernet 1/0/2 of Switch B (a DHCP
relay agent) to ensure user validity.
