DHCP message
with giaddr set to
local address
The number of DHCP client messages received whose gateway
address, giaddr, is already set to an IP address configured on one
of the relay agent's own IP addresses. In this case, another device
is attempting to spoof the relay agent's address. The relay agent
does not relay such packets. A log message gives details for each
occurrence.
Packets with
expired TTL
The number of packets received with TTL of 0 or 1 that might
otherwise have been relayed.
Packets that
matched a discard
entry
The number of packets ignored by the relay agent because they
match a discard relay entry.
