ip-helper: client not getting an IP

[dips00]

Hi,
I am running into an issue where a laptop connected to a switch that has ip-helper configured is not able to get an IP from the dhcp server.
The switch can ping the DHCP server and vice versa. I also tried to setup a separate DHCP server to rule out the dhcp server being the cause but no luck.

Config:
VLan 2 is the vlan for the laptop.

Does the next hop to 10.11.44.3 have a helper-address, or is it directly connected?

10.11.44.3 is the DHCP connected directly to the switch.

 

[burtsbees]

I know. But does the next hop TO this have the ip helper-address command, or is the DHCP server directly connected to the next hop?

You may have to post the rest of the config as nothing for the 10.11.44. subnet is included in your post. Make sure all your layer 2 vlans are created , verify with the show vlan command.

Burtsbees,
correct, the vlan and dhcp server are on the same switch.
