簡(jiǎn)單網(wǎng)絡(luò)管理語(yǔ)言(Simple Network Management Language)是一種類自然語(yǔ)言的腳本語(yǔ)言，它采用snmp火本、telnet危队、ping、dns钙畔、arp茫陆、ssh、tcp擎析、udp簿盅、web等協(xié)議訪問(wèn)網(wǎng)絡(luò)設(shè)備挥下，內(nèi)置smtp協(xié)議用于告警等郵件的發(fā)送，支持excel桨醋、mysql棚瘟、sqlite等3種方式進(jìn)行網(wǎng)管數(shù)據(jù)的存取。

第9章喜最、ping

??“ping”這個(gè)名字源于聲納定位操作偎蘸。目的是為了測(cè)試另一臺(tái)主機(jī)、網(wǎng)絡(luò)設(shè)備是否可達(dá)瞬内。ping是一個(gè)通信協(xié)議迷雪，是TCP/IP協(xié)議的一部分;ping也是Windows、Unix和Linux系統(tǒng)下的一個(gè)命令, ping命令可檢查網(wǎng)絡(luò)是否連通虫蝶，分析和判定網(wǎng)絡(luò)故障章咧。

1、ping語(yǔ)句分析

ping.ip {220.181.12.207} ttl {64} size {32}

ping測(cè)試能真，主機(jī)赁严、設(shè)備ip為220.181.12.207，發(fā)送報(bào)文的ttl值為64粉铐，發(fā)送報(bào)文的長(zhǎng)度為32字節(jié)

ping語(yǔ)句執(zhí)行后误澳，系統(tǒng)創(chuàng)建、更新以下變量秦躯，示例值如下：

ping.dest_ip=[220.181.12.207]忆谓，目的IP

ping.received_responses=[1]，接收到響應(yīng)報(bào)文的個(gè)數(shù)

ping.roundtrip_time_milliseconds=[56]踱承，響應(yīng)時(shí)間（毫秒）

ping.reply_ip=[220.181.12.207]倡缠，應(yīng)答報(bào)文的IP，當(dāng)ttl減小到0的時(shí)候茎活，網(wǎng)絡(luò)設(shè)備應(yīng)答

ping.reply_ttl=[54]昙沦，應(yīng)答報(bào)文的ttl

ping.reply_bytes=[32]，應(yīng)答報(bào)文的長(zhǎng)度

ping.status=[IP_SUCCESS]

ping語(yǔ)句執(zhí)行后载荔，通過(guò)檢查變量“ping.status”是否為“IP_SUCCESS”來(lái)判斷ping是否成功盾饮。
