X440 DHCP Set up

X440 DHCP Set up

I have 9 X440 in a network, with one acting as the "main switch", and have Unifi access points attached to the various switches.   I am trying to make it so the "Main Switch" is the DHCP server for each of our vlans on all switches.   I have configured DHCP etc on each VLAN, and assigned the trunk ports to the dhcp.   In unifi controller, I have created networks that correspond with each vlan, but when I connect via wifi, I still get a self assigned IP.   What am I missing here?

Hi!

I don't think we have enough information to give you an exact answer, but here is a helpful guide with all needed commands:
https://extreme-networks.my.site.com/ExtrArticleDetail?an=000082555

Be sure that the DHCP components are not only configured, but also DHCP is enabled on the relevant port/VLAN with the 'enable dhcp port ...> command.

As a test, if you give the client a static IP/Subnet mask, can it ping the switch IP in the same VLAN?
If not, you may have a layer 2 issue, or an issue with IP configuration.

Hope that helps!

I have everything set up as stated in the guide you posted - only difference is I set it up via the web UI and not the CLI.
