T1600G-18TS 上的 DHCP 服务器不响应请求

我最近购买了一个 T1600G-18TS TP-Link 智能交换机，但无法让 DHCP 服务器在其上工作。

我尝试过

  1. 使用/24网络掩码代替/26
  2. 使用不同的网络类
  3. 保存配置并重启
  4. 禁用然后重新启用 dhcp 服务
  5. 恢复出厂设置并重新配置

我还发现当前固件版本不在TP-Link 支持页面，我的交换机有版本2.0.5但页面上的最新版本是2.0.3。

设备信息

固件版本： 2.0.5 版本 20200304 Rel.33762
硬件版本： T1600G-18TS 2.0

（该gigabitEthernet 1/0/14接口用于配置。）
