Term Definition
DHCP client
messages received
The number of valid messages received from a DHCP client. The count is
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
messages relayed
The number of DHCP client messages relayed to a server. If a message is relayed
to multiple servers, the count is incremented once for each server.
