DHCP Relay on 6024

I have followed the instructions from this article to enable DHCP relay, but cannot get it to work. I have two vlans created on a 5224 with a port channel trunk to a 6224.


http://www.dell.com/downloads/global/products/pwcnt/en/app_note_38.pdf


My config is on 5224

Port 5-8 Vlan 2, Port 9-12 Vlan 3,

ports 23+24 in port channel 1 trunk which allows Vlan 2+3 tagged


6024

Port 2 Vlan 2, port 3 Vlan 3


Ports 23+24 in port channel 1 trunk which allows Vlan 2+3 tagged


Vlan 2 ip address 10.0.2.1, Vlan 3 ip address 10.0.3.1


ip dhcp server 10.0.2.10   (Which is on Vlan 2)


ip dhcp server enable


 


Clients on Vlan 3 can ping DHCP server when given correct ip and gateway, but ipconfig /renew does not obtain address.


The only difference between this and the documented config I can see is that the DHCP server is on a remote subnet.

Any help would be greatly appreciated!

Double check you have:

(config)#ip dhcp relay enable
(config)#ip dhcp relay address 10.0.2.10

If that checks out, take a look at your DHCP server and verify you have a scope properly setup for the VLAN 3 subnet.

Thanks Greg

The issue was with the setup of the scopes. Your help was much appreciated.
