專用ADSL在CISCO 1721上如何配置

yanglinyu

大蝦，我公司申請(qǐng)了一條專用ADSL，IP：218.19.174.8；網(wǎng)關(guān)：218.19.174.1 。DNS：202.96.128.68，請(qǐng)問(wèn)在CISCO 1721上如何配置

zujuhu

是專線就直接配。

yanglinyu

樓上的大蝦，具體點(diǎn)如何？。虛擬ADSL的配置方式我知道。那些有變動(dòng)。

yanglinyu

直接用電話線連接還是要是用ADSL MODEM再與路由器連接。

zujuhu

在專線接入方式中，ＡＤＳＬ設(shè)備提供透明的ＡＴＭ ＰＶＣ通路,ＡＤＳＬ－Ｍｏｄｅｍ采用１４８３－Ｂｒｉｄｇｅ協(xié)議,在路由器上配ip地址,局域網(wǎng)要上internet要做nat就行了.

以下是我根據(jù)具體情況配置的請(qǐng)樓上的大蝦指點(diǎn):

你是專線還是pppoa方式接入
專線方式

　　在專線接入方式中，ＡＤＳＬ設(shè)備提供透明的ＡＴＭ ＰＶＣ通路，ＡＤＳＬ－Ｍｏｄｅｍ采用１４８３－Ｂｒｉｄｇｅ協(xié)議，而業(yè)務(wù)提供點(diǎn)需要專線接入服務(wù)器提供支持，單用戶ＰＣ的ＩＰ地址和接入服務(wù)器接入端口設(shè)在同一網(wǎng)段上。局域網(wǎng)接入時(shí)，為保證用戶數(shù)據(jù)安全以及減少局端路由設(shè)備的操作，需在用戶接入端加路由設(shè)備。

　　專線接入方式可以應(yīng)用于各種數(shù)據(jù)通信場(chǎng)合，特別是企業(yè)專線上網(wǎng)，它具有開通安裝簡(jiǎn)單等特點(diǎn)，但缺乏對(duì)用戶的管理手段。

ＰＰＰｏＡ方式

　　ＰＰＰｏＡ方式中，ＰＰＰ可以由用戶端ＰＣ發(fā)起，也可以由ＡＤＳＬ－Ｍｏｄｅｍ發(fā)起，ＰＰＰｏＡ方式需要有寬帶的接入服務(wù)器支持。

　　ＰＰＰ由用戶ＰＣ發(fā)起時(shí)，ＡＤＳＬ－Ｍｏｄｅｍ需用２５Ｍｂｉｔ／ｓ ＡＴＭ端口通過(guò)５類線用ＲＪ４５頭和用戶ＰＣ相連，用戶ＰＣ需插ＡＴＭ網(wǎng)卡，并安裝客戶端軟件，在ＡＴＭ網(wǎng)卡和寬帶接入服務(wù)器之間建立ＰＶＣ連接。ＰＰＰ由ＡＤＳＬ－Ｍｏｄｅｍ發(fā)起時(shí)，ＡＤＳＬ－Ｍｏｄｅｍ需支持ＰＰＰｏＡ，用戶ＰＣ可以通過(guò)１０ ＢａｓｅＴ以太網(wǎng)口和ＡＤＳＬ－Ｍｏｄｅｍ相連，在ＡＤＳＬ－Ｍｏｄｅｍ和寬帶接入服務(wù)器之間建立ＰＶＣ連接，此時(shí)ＡＤＳＬ－Ｍｏｄｅｍ實(shí)際起到了ＰＰＰ代理的作用。

　　由于ＡＴＭ到桌面存在ＡＴＭ網(wǎng)卡價(jià)格高等局限性，且沒有以太網(wǎng)接入方式普及，因此下面主要討論用戶通過(guò)以太網(wǎng)口接入方式。ＡＤＳＬ－Ｍｏｄｅｍ發(fā)起ＰＰＰ方式時(shí)，用戶ＰＣ不必安裝客戶端軟件，像專線一樣可直接使用瀏覽器軟件上網(wǎng)。ＡＤＳＬ－Ｍｏｄｅｍ在接收到來(lái)自用戶端的數(shù)據(jù)時(shí)，會(huì)向?qū)拵Ы尤敕��?wù)器發(fā)起ＰＰＰ連接；接入服務(wù)器在接收到ＰＰＰ連接后，可以對(duì)ＡＤＳＬ－Ｍｏｄｅｍ進(jìn)行合法性確認(rèn)，向ＡＤＳＬ－Ｍｏｄｅｍ分配ＩＰ地址；ＡＤＳＬ－ Ｍｏｄｅｍ通過(guò)ＮＡＴ功能允許用戶ＰＣ接入。此時(shí)需要ＡＤＳＬ－Ｍｏｄｅｍ支持認(rèn)證功能，并在ＰＰＰｏＡ配置時(shí)，在ＡＤＳＬ－Ｍｏｄｅｍ上設(shè)賬號(hào)及口令；也可以在ＡＤＳＬ－Ｍｏｄｅｍ和接入服務(wù)器只是建立ＰＰＰ連接而不做任何事情�？梢钥闯�，使用ＰＰＰｏＡ?xí)r，用戶端ＰＣ并沒有進(jìn)行ＰＰＰ的認(rèn)證，也無(wú)法通過(guò)ＰＰＰ協(xié)議從接入服務(wù)器獲得ＩＰ地址，而需通過(guò)靜態(tài)分配獲得ＩＰ地址。因此從用戶端看，ＰＰＰｏＡ方式和專線接入方式?jīng)]有任何差別。

　　ＰＰＰｏＡ方式具有用戶接入簡(jiǎn)單的特點(diǎn)，但由于它在接入速率上沒有比專線接入更特別的優(yōu)勢(shì)，且ＡＤＳＬ－Ｍｏｄｅｍ必須支持ＰＰＰｏＡ，因此這種方式在實(shí)際應(yīng)用中很少使用。

問(wèn)題：1.在控制界面里不能PING到ATM0端口。但是在DOS環(huán)境里可以；
          2.PING不到網(wǎng)關(guān)218.19.174.1 ，在以上兩種環(huán)境里。
請(qǐng)大蝦幫助，并提出具體的補(bǔ)充配置。萬(wàn)分感謝！！

你輸入這個(gè)看能不能通,不行的話打開debug atm event把信息抓下來(lái).
