cnMatrix supports DHCP client, relay, and server. Only client is configurable via the cloud. DHCP relay and server are configurable via CLI/Web (local configuration). However, you can execute similar CLI commands for DHCP relay and server in the Switch Group and Switch User-Defined Overrides on cnMaestro and push the configuration. I can provide example of the User-Defined Overrides for dhcp relay or server.
We will extend more configuration coverage on cnmaestro over times.
Thanks.
