<font size="-1">Thats correct. The DHCP Server gets both packages:<br>
<br>
- The original one from the client as broadcast and <br>
- the copied and tagged one from the relay client (in the switch).<br>
<br>
I complained at the manufacturer, that this behavior is not
correct. But the they claimed that it is conform with the standard
and that this configuration would work with their DHCP server.<br>
<br>
Do you know if this issue is exactly described somewhere in the
RFCs? Because then I have something to apply some pressure to the
manufacturer.<br>
<br>
As I understand your last sentence, your relay agents are running
on a router. So therefor the dhcp-server is not in the same
subnet. Or do your relay agents on the APs block the broadcast in
any case?<br>

In the piece of RFC you're quoting the key word is unicast. I
believe it is quite normal behavior for relay agents to leave
unicast packets between the client and server unmodified. However,
I think that you are getting the DHCPDISCOVER both as the original
broadcast from the client and as a unicast from the relay agent.
I don't believe that's normal. Or maybe it is normal for other
products, but at least the relay agents I use here which are
Motorola wireless APs are not behaving that way.
