What is dhcpStatusTotalNoOfNacks?
A running count of DHCPNAK messages received, sent when the server rejects a client's request for a specific address (e.g. because it's already in use or out of the client's valid range). A rising count here often points to clients holding stale leases from a network that has since been renumbered.
