% 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.

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

這次工程中主要是和以前不一樣的,他的光端機收發都是用一根光纖,這個在以前就沒有遇見過的,用一根光纖還是用兩根光纖收發,我的看法是完全取決於:1.如果光端機支持收發一根光纖。2.看電信工程師怎麽調和客戶的需求了。還有一個就這個光端機和協議轉器就集成在一塊的,並且出來的是快速以太網口,一般咱們見到的是光端機和協議轉器是分開的,而且是光端機出來都是串口。
這個城市政府網主要是想新加設備讓內網走專線,也就是走這次新加的設備組成的網
而他們上外網還是走以前的線路,通過ADSL上外網。
這次工程還算是順利吧,就是電信的人等時間有點長,不過等的過程中,我們都老大一在的確定是不是的自己的設備或者是線纜出問題了,我們一在的確定,把我們去的時候帶的兩根網線都用上了,反復測試確定自己的設備沒有問題才做在哪裏等電信的人。
我們在做工程的時候時候一定要把自己的責任和自己負責的設備搞清楚
比如這次我們反復確定自己的設備沒有問題,憑自己做工程的經驗感覺是電信的設備問題
即使我們知道是電信設備哪裏出了問題,我的建議我們還是不要亂動他們的設備
即使動的時候也得他們的人在場,而且是經他們的允許後,我們再做,不然的話這個設備出了故障壞了,責任就是我們的了。
所以大家要慎重考慮好。
就談這麽些吧,看著老大在哪裏設備上敲命令,他比打印機打字都快。我自愧不如啊!
