In a demo environment I have setup a DHCP service (IPv4 only right now) and specified the correct interfaces I want it to run on, I can see in the run command being generated it’s including those, but when I plugin to one of those interfaces I am presented with the following error:
No subnet declaration for swp2 (no IPv4 addresses).
Feb 14 10:15:14 leaf3-1 dhcpd[23323]: ** Ignoring requests on swp2. If this is not what
Feb 14 10:15:14 leaf3-1 dhcpd[23323]: you want, please write a subnet declaration
Feb 14 10:15:14 leaf3-1 dhcpd[23323]: in your dhcpd.conf file for the network segment
Feb 14 10:15:14 leaf3-1 dhcpd[23323]: to which interface swp2 is attached. **
You can see my config here that’s auto generated by NVUE:

I am unsure why DHCPd is asking for interface specific declarations. Based on the docs, by specifying the interfaces via NVUE it would be my hope that NVUE would edit the configs so that those powers have any required declarations needed to work.
