DHCP CLEAR ALL RECORDS
Clears all DHCP information, including all leases and all global DHCP information.
Unlike erase dhcp, this command clears all DHCP information from memory, but leaves the DHCP.DAT file
intact. If you want to clear the information in the DHCP.DAT file as well, enter a save command after dhcp clear
all records.
Note: You cannot abbreviate the word records in the command.
Example:
dhcp clear all records
