The DHCP server detects the conflict by the ping operation. If a conflict address
is found, then the IP address found will be removed from address pool and
marked as conflict and will not be assigned until a network administrator clears
this conflict. If the address is not specified, all conflict addresses are shown.
Otherwise, only the conflict address for the specified address is displayed. The
IP address, Detection Method and Detection Time will be included in the
displayed format. If a duplicate IP address is detected by the DHCP server, the
Detection Method will be marked as "ping" and if the duplicate IP address is
detected by the DHCP client, the Detection Method will be marked as "Gratuitous
ARP".
The following example shows the conflict status of IP address 10.1.1.1.
