IP Helper Commands
The number of valid messages received from a DHCP client. The count is only
incremented 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.
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.
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.
The number of DHCP server messages relayed to a client.
The number of valid UDP packets received. This count includes DHCP
messages and all other protocols relayed. Conditions are similar to those for the
first statistic in this table.
The number of UDP packets relayed. This count includes DHCP messages
relayed as well as all other protocols. The count is incremented for each server to
which a packet is sent.
The number of DHCP client messages received whose hop count is larger than
the maximum allowed. The maximum hop count is a configurable value listed in
show bootpdhcprelay. A log message is written for each such failure. The DHCP
relay agent does not relay these packets.
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.
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.
The number of packets received with TTL of 0 or 1 that might otherwise have
been relayed.
The number of packets ignored by the relay agent because they match a discard
relay entry.
