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

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.

banner login ^C

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

Cisco Router and Security Device Manager (SDM) is installed on this device.

This feature requires the one-time use of the username "cisco"

with the password "cisco". The default username and password have a privilege le

vel of 15.

Please change these publicly known initial credentials using SDM or the IOS CLI.

Here are the Cisco IOS commands.

username <myuser> privilege 15 secret 0 <mypassword>

no username cisco

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

For more information about SDM please follow the instructions in the QUICK START

GUIDE for your router or go to http://www.cisco.com/go/sdm

这次工程中主要是和以前不一样的，他的光端机收发都是用一根光纤，这个在以前就没有遇见过的，用一根光纤还是用两根光纤收发，我的看法是完全取决于：1.如果光端机支持收发一根光纤。2.看电信工程师怎么调和客户的需求了。还有一个就这个光端机和协议转器就集成在一块的，并且出来的是快速以太网口，一般咱们见到的是光端机和协议转器是分开的，而且是光端机出来都是串口。

这个城市政府网主要是想新加设备让内网走专线，也就是走这次新加的设备组成的网

而他们上外网还是走以前的线路，通过ADSL上外网。

这次工程还算是顺利吧，就是电信的人等时间有点长，不过等的过程中，我们都老大一在的确定是不是的自己的设备或者是线缆出问题了，我们一在的确定，把我们去的时候带的两根网线都用上了，反复测试确定自己的设备没有问题才做在哪里等电信的人。

我们在做工程的时候时候一定要把自己的责任和自己负责的设备搞清楚

比如这次我们反复确定自己的设备没有问题，凭自己做工程的经验感觉是电信的设备问题

即使我们知道是电信设备哪里出了问题，我的建议我们还是不要乱动他们的设备

即使动的时候也得他们的人在场，而且是经他们的允许后，我们再做，不然的话这个设备出了故障坏了，责任就是我们的了。

所以大家要慎重考虑好。
