A Global DHCP Configuration contains all the settings required to run a service instance as a DHCP server. A DHCP config profile is configured and applied locally to the service instance. All configuration settings are inherited from the Global DHCP Configuration into the DHCP config profile by default. If there are no changes made to the DHCP config profile, it would be an exact copy of the Global DHCP Configuration. For For more information, see Global DHCP Configuration.
However, in some instances, you may need to configure settings that are different from the Global DHCP Configuration. In such instances, you can override the values inherited into the DHCP config profile. There are only two configurations available for inheritance in the DHCP config profile:
Inherit - this is the default setting. The values for the particular setting exactly matches the value provided in the Global DHCP Configuration.
Override - you can toggle the configuration to Override and provide alternate values. Use this setting when you want to provide a value for a setting that is different from the one specified in Global DHCP Configuration.

You cannot delete a DHCP config profile if it is in use by a service instance. A DHCP config profile may be assigned to multiple service instances. |
The DHCP config profile is applied locally to a service instance. The DHCP config profile contains all the settings required for the particular service instance. For example, an organization creates a Global DHCP Configuration at the head office. The branch office can deploy a DHCP server ( service instance) and inherit values from the Global DHCP Configuration. For settings unique to the particular branch office, the organization creates a DHCP config profile to override settings in the Global DHCP Configuration and apply it to the service instance. The following diagram shows the stage at which the DHCP config profile is configured:
...
| hidden | true |

| name | DHCP_Config_Profile.drawio |

An organization may need to configure different values in the Global DHCP Configuration and DHCP config profile. For example, an organization may have long lease times for desktops, laptops, and printers. However, IoT devices like air quality monitoring, electrical panel monitoring, and leak monitoring systems may have short lease times. Although the Global DHCP properties have longer lease times, the DHCP Config profile may need to be configured with shorter lease times. The DHCP Config profile is applied to the service instance that manages the IoT devices. The DHCP config profile and the Global DNS properties are applied together as shown in the diagram:
