Starting from QTS 5.2.4 and QuTS hero h5.2.4, the DHCP server configuration in Network & Virtual Switch has been enhanced to provide more flexibility and control. Key updates include:

• Support for configuring network adapters with DHCP-assigned IP addresses as DHCP servers, enabling more dynamic and adaptable IP management.
• Ability to reserve and unreserve IP addresses for client devices, with the option to assign reserved IP addresses during DHCP server setup.
• Simplified DHCP server configuration steps, making the DHCP server configuration and management more straightforward and user-friendly.

Create a DHCP server

1. Log in to your NAS as a NAS administrator or a user with the "System management" delegated role.
   Note

   For details on delegated roles, see "Privilege Settings > Delegated administration" in the QTS User Guide or the QuTS hero User Guide.

Network & Virtual Switch creates the DHCP server.

Note

• When editing DHCP server settings, the interface IP address cannot be modified.
• The Enable DHCP Server option can be configured during the edit process but is not available when creating a new DHCP server.
• You can assign the current DHCP IP address of a client device as a reserved IP address to ensure it always receives the same address from the DHCP server.
