please configure dhcp select interface first

这是一个命令行提示，意思是在配置 DHCP 服务之前需要先选择接口（interface）。接口通常是指网络设备上的物理或逻辑接口，例如网卡或 VLAN 接口。您需要先使用类似于 `select interface <interface-name>` 的命令来选择要配置 DHCP 服务的接口，然后才能继续进行 DHCP 配置。

[Huawei-GigabitEthernet0/0/0]dhcp server dns-list 192.168.1.100 Error:Please configure dhcp select interface first.

这个错误提示表明在配置DHCP服务器的DNS列表之前，需要先配置DHCP服务器选择的接口。因此，你需要先配置DHCP服务器选择的接口，然后再配置DNS列表。可以按照以下步骤进行配置：

1. 进入接口视图：`[Huawei] interface GigabitEthernet 0/0/0`

2. 配置接口为DHCP服务器选择的接口：`[Huawei-GigabitEthernet0/0/0] dhcp select interface`

3. 返回DHCP服务器视图：`[Huawei-GigabitEthernet0/0/0] quit`

4. 配置DNS列表：`[Huawei] dhcp server dns-list 192.168.1.100`

完成以上步骤后，DHCP服务器的DNS列表就配置成功了。

dhcp select interface

As an AI language model, I do not have access to your specific network configuration. However, I can provide a general answer to your question.

When configuring DHCP on a network device, you may need to specify the interface that will be used to distribute IP addresses to clients. This is typically done by using the "dhcp select interface" command.

For example, if you have a router with multiple interfaces (e.g., LAN, WAN, DMZ), you may want to configure DHCP to only distribute IP addresses on the LAN interface. To do this, you would use the following command:

dhcp select interface lan

This would tell the router to only distribute IP addresses on the LAN interface, and not on the other interfaces.

Note that the exact syntax of the command may vary depending on the device and operating system you are using. It is always best to consult the documentation for your specific device to ensure you are using the correct command.
