目前出现的几种情况有点不懂

1.Router(config-if)#ppp authentication pap
AAA: Warning, authentication list "default" is not defined for PPP.

2.用show run每看一次配置，line 33 40下面的speed都会变

3.拨号时能听到拨号音，然后跳出来“正在验证用户名和密码”，然后就有错误出来了

通常是"错误619 指定的设备没有连接"
"错误31 连接到系统上的设备没有发挥作用"
"629的错误，说是被远程计算机断开"

同样的设备，同样的配置重新拨号一次，错误就可能会从31变成619


4.00:49:10: %LINK-3-UPDOWN: Interface Serial1/0, changed state to up
00:49:33: %LINK-5-CHANGED: Interface Serial1/0, changed state to reset
这几行一开始来是再跳的，不知道为什么

---------------------------------------------------------------

（1）如果希望logging保存debug的信息，需要加一行：logg buffer debug。

（2）问题一已经提示了：你需要配置aaa，
aaa authen ppp default local

（3）其实你已经在line上配置了login local，在异步口上，不配置ppp authen，也可以达到使用local进行拨入身份认证的目的。

Router#debug ppp neg
PPP protocol negotiation debugging is on


还是这样，那边还是到了用户名和验证的地方就下不去了，跳出来个629的错误Router#show run

这个是现在的配置

对了，那个speed怎么老是在跳啊

------------------------------------------------------------------------------

1.Router(config-if)#ppp authentication pap
AAA: Warning, authentication list "default" is not defined for PPP.

这个问题解决了


但是用户名和密码验证的问题还是存在


show run 3次，看到的speed都是不一样的。

show line3次，看到的 38 TTY 19200/19200 - inout - - - 0 72 0/0 Se1/

也是不一样的

情况依旧

首先要debug ppp neg
loggin buffered

show loggin后如果能看到lcp的信息，这次我是在能看到LCP的信息后，还是同样的现象，在用户名和密码卡住了，然后修改了

async mode de
为
async mode interactive
然后就可以了


不过有些线路拨不上来，有些可以，但原来有些可以拨不上来的线路有时候也是可以的。
