Secondary SNTP Server Address (次要 SNTP 伺服器位址) 鍵入伺服器位址 (最多 64 個字元)。 次要SNTP 伺服器位址用作主要 SNTP 伺服器位址的備份。如果主要伺服器無法使用,機器將聯絡次要 SNTP 伺服器。 Primary SNTP Server Port (主要 SNTP 伺服器連接埠) Secondary SNTP Server Port (次要 SNTP 伺服...
勾选“SNTP Client”,在“Time Zone中填入所在地时区,中国是+08:00。在“SNTP Mode”下拉框中选择“Poll”,然后点击“Set Value”按钮生效后出现“SNTP Server IP Address”对话框,在其中输入SNTP服务器地址,即为步骤一中工控机的的IP地址。SNTP服务器端口号“SNTPServer Port”保持123不变。在“Poll Interval”...
Specifies the broadcast address or the multicast group address. The SNTP server will send the broadcast packet or the multicast packet to it. By default, it's "255.255.255.255". Target port Specifies the number of port that the NTP/SNTP broadcast or multicast packet will be sent to. By def...

检查你的SNTP客户端配置,确保配置的SNTP服务器地址和端口是正确的。 示例配置(假设使用NTP协议,端口通常为123): python # 伪代码示例,实际配置可能因客户端而异 sntp_server = "time.google.com" sntp_port = 123 测试与SNTP服务器的连通性: 使用telnet或nc(netcat)工具测试与SNTP服务器的连通性。 例如,使...

SNTP (简单网络时间协议)是NTP的简化版本,在实现时,计算时间用了简单的算法,性能较高。而精确度一般也能达到 1 秒左右,也能基本满足绝大多数场合的需要。...由于SNTP 的报文和NTP 的报文是完全一致的,所以设备实现的SNTP Client 能完全兼容 NTP Server 1、基础路由
