Displaying and maintaining the DHCP server
![[IMPORTANT: ]](images/important.png) | IMPORTANT: A restart of the DHCP server or execution of the reset dhcp server ip-in-use command deletes all lease information. The DHCP server denies any DHCP request for lease extension, and the client must request an IP address again. | |
Execute display commands in any view and reset commands in user view.
