ip dhcp ping packets
Use the ip dhcp ping packets command in Global Configuration mode to
configure the number of pings sent to detect if an address is in use prior to
assigning an address from the DHCP pool. If neither ping is answered, the
DHCP server presumes the address is not in use and assigns the selected IP
address.
