简单网络管理语言(Simple Network Management Language)是一种类自然语言的脚本语言，它采用snmp、telnet、ping、dns、arp、ssh、tcp、udp、web等协议访问网络设备，内置smtp协议用于告警等邮件的发送，支持excel、mysql、sqlite等3种方式进行网管数据的存取。

简单网络管理语言（snml）支持CLI（命令行接口）和SNMP（简单网络管理协议）两种方式自动化的进行网络设备配置和管理。CLI 是基于telnet、ssh的人机交互界面，用于设备的参数配置和状态的查看。SNMP 是基于通讯协议的管理工具,实现网络设备参数的自动化监控和远程配置。
网络设备的配置和管理的新技术是SDN（Software Defined Netrork）。软件定义网络是2006年斯坦福大学提出的网络设备分层编程控制系统，全新的网络设备自动化配置和管理体系。

第9章、ping
“ping”这个名字源于声纳定位操作。目的是为了测试另一台主机、网络设备是否可达。ping是一个通信协议，是TCP/IP协议的一部分;ping也是Windows、Unix和Linux系统下的一个命令, ping命令可检查网络是否连通，分析和判定网络故障。
1、ping语句分析
ping.ip {220.181.12.207} ttl {64} size {32}
ping测试，主机、设备ip为220.181.12.207，发送报文的ttl值为64，发送报文的长度为32字节
ping语句执行后，系统创建、更新以下变量，示例值如下：
ping.dest_ip=[220.181.12.207]，目的IP
ping.received_responses=[1]，接收到响应报文的个数
ping.roundtrip_time_milliseconds=[56]，响应时间（毫秒）
ping.reply_ip=[220.181.12.207]，应答报文的IP，当ttl减小到0的时候，网络设备应答
ping.reply_ttl=[54]，应答报文的ttl
ping.reply_bytes=[32]，应答报文的长度
ping.status=[IP_SUCCESS]
ping语句执行后，通过检查变量“ping.status”是否为“IP_SUCCESS”来判断ping是否成功。
