NOTE:
Using the save command does not save DHCP server lease information. Therefore, when the system boots
up or the reset dhcp server ip-in-use command is executed, no lease information will be available in the
configuration file. The server will deny the request for lease extension from a client and the client needs to
request an IP address again.
DHCP server configuration examples
DHCP networking involves two types:
• The DHCP server and client are on the same subnet and perform direct message delivery.
• The DHCP server and client are not on the same subnet and communicate with each other via a
DHCP relay agent.
The DHCP server configuration for the two types is the same.
Static IP address assignment configuration example
Network requirements
As shown in Figure 102, Router A (DHCP client) and Router B (BOOTP client) obtain a static IP address,
DNS server address, and gateway address from the Firewall (DHCP server) respectively.
The MAC address of interface GigabitEthernet 0/1 on Router B is 000f-e200-01c0. The client ID of
interface GigabitEthernet 0/1 on Router A is
3030-3066-2e65-3230-302e-3030-3032-2d45-7468-6572-6e65-7430-2f30.
