When an S series switch functions as a DHCP server, what are precautions for configuring Option3 in the response message sent by the DHCP server

In V100R003, V100R006, V200R001, and later versions, when an S series switch (excluding the S1700) serves as the DHCP server, if a client is not connected to the server through a relay agent, the content in Option3 of the response message sent by the server is the address of the VLANIF interface on the switch. However, the content in Option3 should be another address in some scenarios. Configure Option3 based on the following rules:
1. Configure the global address pool mode.
2. Set gateway-list ip-address to be the configured address in the address pool view. This address must be located on the same network segment as the address of the DHCP server.
