below min
The number of DHCP client messages received with secs fields
that are less than the minimum value. The minimum secs value
is a configurable value and is displayed in show bootpdhcprelay.
A log message is written for each such failure. The DHCP relay
agent does not relay these packets.
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.
