Dell n2048 Switch not passing dhcp

I am trying to add a switch in between my modem and my firewall.  The modem is trying to give the firewall a DHCP IP address but it will not pass.  If I plug in a Fortinet switch it works.  I tried resetting the switch to factory and it didn't work.  I then tried spanning-tree portfast and it still isn't working.  Below is the config.  I was using port 45 and port 46.

 

!Current Configuration:

Hello littleclimate,

 

Are you getting a connection?

'#show interfaces status'

'#show interfaces configuration'

 

May try '# no shutdown' on the ports you are using.

 

In not sure if this could help some more - Page 1173 Configuring the DHCP Server (Web)

https://dell.to/3TvTNfJ

Please note we are unable assist directly in making new configurations, but we do have professional services which can help you to deploy the configuration you need. You may consider contacting Dell Sales department for a professional deployment if needed. 

I hope the resources I am able to supply will be helpful for you.

Hi @littleclimate,

 

Based on your first post comment, I notice, there is no VLAN 2 configuration done. Looks like you only configured interfaces in VLAN 2. You might want to look at the user guide for VLAN configuration on IP Helper and DHCP Relay.
