incremented only if IP helper is enabled globally, the ingress routing interface is up,
and the packet passes a number of validity checks, such as having a TTL>1 and
having valid source and destination IP addresses.
DHCP client
The number of DHCP client messages relayed to a server. If a message is relayed
messages relayed
to multiple servers, the count is incremented once for each server.

DHCP message with
The number of DHCP client messages received whose secs field is less than the
secs field below min
minimum value. The minimum secs value is a configurable value and is displayed in

giaddr set to local
already set to an IP address configured on one of the relay agent's own IP
