Windows 2003 Server DHCP Option 82

Dear all,

I have configured the option 82 on my MS 2003 server standard edition SP1,in
order to permit at the clinents that are on a layer 3 switch to obtain the
right ip address when move from a Vlan to another Vlan.

The network appliences are just configurated to use the option 82 providing
the "Vlan id" information to the MS Server 2003, I have try to move one
client from the "Vlan A" to the "Vlan B" and the MS DHCP server continue to
assign the "Vlan A" ip address instead to assign a "Vlan B" ip address.(both
VlanA and ValnB scope are configured and active on the server).

How I can configure the DHCP server to fix this problem ?

Thanks & Regards

Igor.

Hi

I'm not familiar with the use of option 82, but if I'm understanding your
question correctly, you are using port-based VLANs and have one subnet per
VLAN. You want clients to get the right IP address for the VLAN they're on.

If I'm interpreting your question correctly, you can almost certainly set a
bootp relay (RFC 1542) option on your layer 3 switch. This may also be
referred to as an IP helper. How you configure this will depend on your
switch, but on the HP ProCurve switches, it is the "ip helper-address"
command.

The following link has some more info on DHCP/BOOTP relay.

Hope this helps
