How to configure automatic reclaim of conflicting addresses in a DHCP address pool

Latest reply: Dec 29, 2018 02:26:25 306 5 7 1

Starting with V2R9, the switch adds the ability to automatically reclaim conflicting addresses. Because some

networks may have address conflicts caused by manually configuring static IP addresses. In this case, the 

DHCP server will always set this part of the address as the conflicting address. Only when the available 

address is allocated, the DHCP server will select the available IP address from the conflicting address for 

allocation. In order to recover the conflicted address as soon as possible, management The commander

 can execute this command on the device:

<HUAWEI> system-view

[HUAWEI] ip pool global1

[HUAWEI-ip-pool-global1] conflict auto-recycle interval day 1 //Configure the automatic reclaim interval to 1 day, and the time can be hour, 

minute and day.

Dynamic Host Configuration Protocol (DHCP) is used to dynamically manage and configure the IP addresses for users in a centralized manner. DHCP adopts the client/server mode for communication. The client applies to the server for configurations (including IP address, subnet mask, and default gateway), and the server replies with corresponding configuration information based on policies.

The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on UDP/IP networks whereby a DHCP server dynamically assigns an IP address and other network configuration parameters to each device on a network so they can communicate with other IP networks
