網(wǎng)絡(luò)工程師成長(zhǎng)日記365-IBIS西安工程回憶錄

這是我的第365篇原創(chuàng)文章，記錄網(wǎng)絡(luò)工程師行業(yè)的點(diǎn)點(diǎn)滴滴，結(jié)交IT行業(yè)有緣之人

我的第一次真實(shí)工程經(jīng)歷
5.26日這一天我的心情是格外的興奮，激動(dòng)。
因?yàn)槲医K于有機(jī)會(huì)去體驗(yàn)真實(shí)的工程操作，這是我盼望已久的。
早上我起的比平常早一個(gè)多小時(shí)，準(zhǔn)備了許久才滿懷希望的走出家門坐上公交車，不知道怎么搞得平時(shí)堵的不能動(dòng)彈的馬路，那天格外的順暢。到了陽(yáng)明國(guó)際，我看了看表時(shí)間不到七點(diǎn)（哈哈，來(lái)得真早）干脆就坐在門口等老大，一邊等我就一邊想會(huì)不會(huì)讓我親自上手操作呢，越想越興奮時(shí)間不知不覺(jué)已經(jīng)過(guò)去半個(gè)小時(shí)了。
剛好老大也來(lái)了，七點(diǎn)半（也挺早）因?yàn)槟沁呉笪覀儼它c(diǎn)五十就要到達(dá)目的地，所以我倆不敢耽擱時(shí)間。

檢查好應(yīng)該帶的東西，consle線，筆記本，交叉線等等，我，老大，楊工就急急忙忙的出發(fā)了，坐上車我們心里總想著讓車走快點(diǎn)恨不得車能飛起來(lái)，結(jié)果我們都傻眼了--堵車。
沒(méi)辦法我們只能祈禱路快點(diǎn)通，借著這個(gè)機(jī)會(huì)，老大讓我們看了上海聯(lián)通公司給我們發(fā)過(guò)來(lái)的工程需求，哇塞全是英文，
還好有老大他簡(jiǎn)單給我們介紹了這次工程概況---為西安ibis酒店裝配一臺(tái)cisco的2811路由器，以及三個(gè)模塊（）并且在上邊配置MPLS ×××（這可是我第一次聽(tīng)說(shuō)，長(zhǎng)了見(jiàn)識(shí)了，呵呵）。
聽(tīng)著聽(tīng)著已經(jīng)到了大差市，下了車我們就開(kāi)始找地方，還好我對(duì)西安比較熟悉（嘿嘿），大概走了不到500米我突然看見(jiàn)一個(gè)大大牌子西安宜必思酒店。
我們到了，時(shí)間八點(diǎn)半剛剛好，想著馬上就能見(jiàn)到各式各樣的網(wǎng)絡(luò)設(shè)備及拓?fù)湫睦砭鸵魂嚫`喜。
這時(shí)老大給酒店網(wǎng)絡(luò)管理員打電話，結(jié)果我們就更傻眼了，原來(lái)人家也堵車，哎呀?jīng)]辦法等吧。
九點(diǎn)十分，網(wǎng)管終于到了，再他的指引下我們來(lái)到ibis的機(jī)房。
進(jìn)去以后，好冷（給設(shè)備降溫用的空調(diào)），機(jī)房不大但是很整齊，各式設(shè)備擺放的井井有條，經(jīng)過(guò)和網(wǎng)管的交談得知人家用的設(shè)備是一樣兩臺(tái).......好有錢呀。
其中設(shè)備主要有cisco的2950交換機(jī)，電話交換機(jī)，以及中國(guó)電信贈(zèng)送的華為交換機(jī)，協(xié)議轉(zhuǎn)換器，其中最引人注目的就是一臺(tái)和印度連接的juneper防火墻--這是我以前見(jiàn)都沒(méi)見(jiàn)過(guò)的東西，真是大飽了眼福。
接下來(lái)，我們從網(wǎng)管那里得知現(xiàn)在酒店通過(guò)網(wǎng)通的光纖和上海的總部進(jìn)行直接的通信，這就是要用到2811路由器，還有聯(lián)通的協(xié)議轉(zhuǎn)換器（V.35接口）

工程正式開(kāi)始，首先酒店方的網(wǎng)管打開(kāi)了2811路由器的包裝箱，終于現(xiàn)出廬山真面目了。
拿到設(shè)備后老大讓我們檢查了設(shè)備數(shù)目和收貨單上是不是匹配（這是很重要的），其中包括三個(gè)模塊，兩根直通線，一根（一端是串行口一端是V.35）。
正當(dāng)我們要裝模塊的時(shí)候，發(fā)現(xiàn)模塊已經(jīng)裝配好了（真是爽，可是又覺(jué)得遺憾少了親自裝配模塊的經(jīng)歷）。
打開(kāi)筆記本電腦連上consle線，連上路由器的串行口，另一端接到了聯(lián)通光纖的協(xié)議轉(zhuǎn)換器上，一切準(zhǔn)備妥當(dāng)。
打開(kāi)電源后，機(jī)器運(yùn)行正常，登陸到超級(jí)終端后，show running 后發(fā)現(xiàn)路由器的基本配置已經(jīng)被上海的工程師刷到上邊了，并且運(yùn)行了MPLS ××× ，show ip int brief后發(fā)現(xiàn)物理鏈路狀態(tài)已經(jīng)是UP了，可是我們發(fā)現(xiàn)二層協(xié)議是down的，因?yàn)槭嵌訁f(xié)議所以不存在路由協(xié)議，ip地址之類的問(wèn)題。
那是什么原因呢，我們手動(dòng)激活端口后，狀態(tài)up了之后又跳轉(zhuǎn)到down，經(jīng)過(guò)思考會(huì)不會(huì)是封裝格式不對(duì)，封裝成ppp后還是沒(méi)反應(yīng)。

我們陷入了沉思，突然楊工說(shuō)能不能把寄存器的值修改成0x2142，結(jié)果還是不行。
接下來(lái)，老大給上海的工程師打電話，對(duì)方說(shuō)是兩端的速率不一致，要打電話和西安聯(lián)通線路工程師核實(shí)一下（因?yàn)榫频暧玫氖?12k，擔(dān)心ce端把線接到了2m的口上），很快人家回復(fù)沒(méi)問(wèn)題。
我們排除了路由器的問(wèn)題，物理連接的問(wèn)題，后來(lái)老大說(shuō)是要做打環(huán)測(cè)試，可是我們沒(méi)有現(xiàn)成的工具做不成的，這下可難住我們了，后經(jīng)過(guò)聯(lián)系聯(lián)通的線路工程師，說(shuō)可能是線路出了問(wèn)題。
不一會(huì)人家就過(guò)來(lái)了，經(jīng)過(guò)打環(huán)確認(rèn)線路沒(méi)有問(wèn)題，那會(huì)是什么問(wèn)題呢，我都快崩潰了。
老大再次打電話給上海工程師，對(duì)方回復(fù)說(shuō)是讓西安聯(lián)通數(shù)據(jù)部門ping一下pe到ce，我們想了二層協(xié)議沒(méi)up怎么會(huì)ping通。
又一次失敗了，已經(jīng)12點(diǎn)了，人家都去吃飯了可我們沒(méi)心思吃（其實(shí)我已經(jīng)餓得不行了）。
這時(shí)，聯(lián)通工程師建議我們先去吃飯，他再找找協(xié)轉(zhuǎn)的問(wèn)題。

匆匆吃完飯，回到ibis酒店繼續(xù)討論，我都有點(diǎn)退縮的想法，就在這時(shí)聯(lián)通工程師帶來(lái)了好消息，說(shuō)是協(xié)轉(zhuǎn)的速率跳線開(kāi)關(guān)可能設(shè)置不對(duì)，拆下協(xié)轉(zhuǎn)我們驚奇的發(fā)現(xiàn)協(xié)轉(zhuǎn)背后還有幾組微小的跳線開(kāi)關(guān)，我的天，經(jīng)過(guò)正確的設(shè)置后（調(diào)成512k），安轉(zhuǎn)好協(xié)轉(zhuǎn)后，二層協(xié)議立刻就up，show ip bgp ，show ip route后發(fā)現(xiàn)出現(xiàn)bgp路由信息，ping 對(duì)方的ip地址是通的。
我們高興得都蹦了起來(lái)，接下來(lái)進(jìn)行了調(diào)試，一切正常，這時(shí)已經(jīng)是下午四點(diǎn)了。我們終于長(zhǎng)舒了一口氣
這次工程經(jīng)歷，我不僅學(xué)到在學(xué)校學(xué)不到的知識(shí)，而且見(jiàn)到很多以前沒(méi)見(jiàn)過(guò)的設(shè)備。在
實(shí)際的工程中，我們會(huì)遇到一些非常棘手的問(wèn)題，只要我們頭腦清醒的去回憶我們?cè)?jīng)學(xué)到的知識(shí)，我相信沒(méi)有處理不了的問(wèn)題。
這次工程經(jīng)歷使我認(rèn)識(shí)到我自身知識(shí)的不足，再接下來(lái)的學(xué)習(xí)中，我要踏踏實(shí)實(shí)的掌握每一個(gè)知識(shí)點(diǎn)，原理。
只有這樣，才會(huì)在今后真正的工作中得心應(yīng)手。

不能泄露商業(yè)信息，所以我就把不重要的配置給大家看看

banner exec ^C
% Password expiration warning.

Cisco Router and Security Device Manager (SDM) is installed on this device and
it provides the default username "cisco" for one-time use. If you have already
used the username "cisco" to login to the router and your IOS image supports the
"one-time" user option, then this username has already expired. You will not be
able to login to the router with this username after you exit this session.

It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.

username <myuser> privilege 15 secret 0 <mypassword>

Replace <myuser> and <mypassword> with the username and password you want to
use.
