Bootdhcprelay and Vlans 6224
Hi, I have searched this forum and found a lot of help regarding this problem. I have 3 Vlans configured on my PowerConnect 6224 and a DHCP server Windows Server 2000 with different subnet scopes, as far as I know I need to set-up a bootdhcprelay server and enable bootdhcprelay which I have done, but when I try to get a dhcp address from my client pc I don't get an address. When I configure the client with a manual IP I can communicate as expected.
Here is my running-config, is there anything wrong?
!Current Configuration:
!System Description "Dell 24 Port Gigabit Ethernet, 2.0.0.12, VxWorks5.5.1"

you are correct that all you should have to do is the bootpdhcp servern enable and teh bootpdhcp server ip address
Why are all the ip helper addresses set up, not necessarily wrong, but ...
I see your ports are created as general, and mixed as far as access and vlan overlapping.
so what are g1,2,3, and 24? are they supposed to be access ports not carrying tagged traffic or are they supposed to be 802.1q ports?
where does the dhcp server reside, local to the switch?

Would I dare say that "ip dhcp filtering" in your config has something to do with this?
Use the "ip dhcp filtering trust" interface configuration command to exclude specific ports.
