obtain correct IP addresses and other network parameters from Switch A. You can use the display dhcp
server ip-in-use command on the DHCP server to display the IP addresses assigned to the clients.
DHCP user class configuration example
Network requirement
As shown in Figure 19, the DHCP relay agent (Switch A) forwards the packets from DHCP clients to the
DHCP server. Enable switch A to support Option 82 so that switch A can add Option 82 in the DHCP
requests sent by the DHCP clients.
The DHCP server (Switch B) assigns IP addresses and other configuration parameters to the DHCP clients.
If the DHCP requests the DHCP server receives contain Option 82, the server assigns IP addresses in the
range of 10.10.1.2 to 10.10.1.10 to the clients.
For clients in subnet 10.10.1.0/24, the DNS server address is 10.10.1.20/24 and the gateway address is
10.10.1.254/24.
