no ip dhcp excluded-address low-ip-address [ high-ip-address ]
Parameter Description

Excludes the IP address, or excludes the start IP address
within the range of the IP address.
Parameter
Description
high-ip-address
Excludes the end IP address within the range of the IP
address.
Defaults
The DHCP server assigns the IP addresses of the whole address pool by default.
Command
Mode
Global configuration mode
Usage Guide
If no excluded IP address is configured, the DHCP server attempts to assign all IP addresses in the
DHCP address pool. This command can reserve some IP addresses for specific hosts to prevent the
DHCP from assigning these addresses to the DHCP client, and define the excluded IP address
accurately to reduce the conflict detecting time when the DHCP server assigns the address.
Configuration
Examples
The following example configures that the DHCP server will not assign the IP addresses within
192.168.12.100 to 150.
Ruijie(config)# ip dhcp excluded-address 192.168.12.100 192.168.12.150
