DHCP Server Conflicts Information
DHCP Server Conflicts Information Fields
Description
The IP address that has been detected as a duplicate.
The method used to detect the conflict, which is one of the following:
• Gratuitous ARP The DHCP client detected the conflict by broadcasting an ARP request to the
address specified in the DHCP offer message sent by the server. If the client receives a reply to the
ARP request, it declines the offer and reports the conflict.
• Ping The server detected the conflict by sending an ICMP echo message (ping) to the IP address
before offering it to the DHCP client. If the server receives a response to the ping, the address is
considered to be in conflict and is removed from the pool.
• Host Declined The server received a DHCPDECLINE message from the host. A DHCPDECLINE
message indicates that the host has discovered that the IP address is already in use on the
network.
The time when the conflict was detected in days, hours, minutes, and seconds since the system was
last reset (i.e., system up time).
