It takes a period of time for a DHCP server to send FORCERENEW messages. To stop the server from sending FORCERENEW messages, run the stop send forcerenew command.
Example
# Stop a DHCP server from sending FORCERENEW messages in the view of an address pool named huawei.
<HUAWEI> system-view
[~HUAWEI] ip pool huawei server
[~HUAWEI-ip-pool-huawei] stop send forcerenew
