Note:
Executing the save command will not save the lease information on a DHCP server to
the flash memory. Therefore, the configuration file contains no lease information after
the DHCP server restarts or you clear the lease information by executing the reset
dhcp server ip-in-use command. In this case, any lease-update requests will be
denied, and the clients must apply for IP addresses again.

2.6 DHCP Server Configuration Example

Currently, DHCP networking can be implemented in two ways. One is to deploy the
DHCP server and DHCP clients in the same network segment. This enables the
clients to communicate with the server directly. The other is to deploy the DHCP
server and DHCP clients in different network segments. In this case, IP address
To do...
display dhcp server conflict { all | ip
ip-address }
display dhcp server expired { ip
ip-address | pool [ pool-name ] | interface
[ interface-type interface-number ] all }
display dhcp server free-ip
display dhcp server ip-in-use { ip
ip-address | pool [ pool-name ] | interface
[ interface-type interface-number ] all }
display dhcp server statistics
display dhcp server tree { pool
[ pool-name ] | interface [ interface-type
interface-number ] | all }
reset dhcp server conflict { all | ip
ip-address }
reset dhcp server ip-in-use { ip
ip-address | pool [ pool-name ] | interface
[ interface-type interface-number ] | all }
reset dhcp server statistics
