Figure 9-27. IP Helper Statistics
The IP Helper Statistics page contains the following fields:
•
DHCP Client Messages Received
— The number of valid messages received from a DHCP client.
The count is only increased 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 increased once for each server.
•
DHCP Server Messages Received
— The number of DHCP responses received from the DHCP server.
This count only includes messages that the DHCP server unicasts to the relay agent for relay to the
client.
•
DHCP Server Messages Relayed
— Specifies the number of DHCP server messages relayed to a client.
•
UDP Client Messages Received

DHCP messages and all other protocols relayed. Conditions are similar to those for the first statistic in
this table.
•
UDP Client Messages Relayed
— The number of UDP packets relayed. This count includes DHCP
messages relayed as well as all other protocols. The count is increased for each server to which a packet
is sent.
