思科路由器恢復(fù)IOS方法及開(kāi)啟多用戶(hù)Telnet權(quán)限方法
今天小編就給大家介紹下思科路由器交換機(jī)簡(jiǎn)單的X-MODEM恢復(fù)IOS的方法以及開(kāi)啟多用戶(hù)Telnet權(quán)限和Logo查看方法。
首先小編就給大家介紹思科路由交換機(jī)簡(jiǎn)單的X-Modem恢復(fù)IOS方法:
1、用控制線(xiàn)連接思科路由交換機(jī)console口與計(jì)算機(jī)串口1,用帶有xmodem功能的終端軟件連接(win2000 and xp的超級(jí)終端就帶這功能)。
2、設(shè)置連接方式為串口1(如果連接的是其他串口就選擇其他串口),速率9600,無(wú)校驗(yàn),無(wú)流控,停止位1?;蛘唿c(diǎn)擊默認(rèn)設(shè)置也可以。
3、連接以后計(jì)算機(jī)回車(chē)出現(xiàn)思科路由交換機(jī)無(wú)ios的界面,一般的提示符是:switch:
4、拔掉思科路由交換機(jī)后的電源線(xiàn)重新啟動(dòng)交換機(jī)。
5、在超級(jí)終端輸入:switch:flash_init,會(huì)出現(xiàn)如下提示:Initializing Flash...
6、輸入拷貝指令:switch:copy xmodem: flash:image_filename.bin,出現(xiàn)如下提示:Begin the Xmodem or Xmodem-1K transfer now...
7、系統(tǒng)提示不斷出現(xiàn)C這個(gè)字母就可以開(kāi)始傳文件了。
8、點(diǎn)擊超級(jí)終端菜單:傳送---發(fā)送文件,在協(xié)議選項(xiàng)中選擇Xmodem或者Xmodem-1K協(xié)議,然后選擇ios的影像文件(*.bin),開(kāi)始傳送。
9、因?yàn)椴荒芨乃俾剩詡魉偷煤苈?,我的大概傳送?0分鐘左右,請(qǐng)耐心等待。
10、傳送完畢后提示:File "xmodem:" successfully copied to ....,switch:
11、在提示符下輸入switch:boot,啟用新的ios系統(tǒng)。
12、重新加電完成恢復(fù)工作。
Cisco 路由器 使用Xmodem恢復(fù)IOS方法
在沒(méi)有IOS的情況下 系統(tǒng)只能進(jìn)入Rommon狀態(tài),在這個(gè)狀態(tài)下只能見(jiàn)到如下命令:
rommon 8 > ?
alias set and display aliases command
boot boot up an external process
break set/show/clear the breakpoint
confreg configuration register utility
cont continue executing a downloaded image
context display the context of a loaded image
cookie display contents of cookie PROM in hex
dev list the device table
dir list files in file system
dis display instruction stream
dnld serial download a program module
frame print out a selected stack frame
help monitor builtin command help
history monitor command history
meminfo main memory information
repeat repeat a monitor command
reset system reset
set display the monitor variables
stack produce a stack trace
sync write monitor environment to NVRAM
sysret print out info from last system return
tftpdnld tftp image download
unalias unset an alias
unset unset a monitor variable
xmodem x/ymodem image download
在這個(gè)模式下,輸入Xmodem
rommon 9 > xmodem
會(huì)提示如下警告:
WARNING: All existing data in bootflash will be lost!
Invoke this application only for disaster recovery.
Do you wish to continue? y/n [n]: y
Ready to receive file ? …
然后在超級(jí)終端的傳送欄目=> 選擇發(fā)送選項(xiàng) => 再選擇Xmodem 并指明IOS所在的路徑即開(kāi)始上傳IOS,等待時(shí)間很長(zhǎng),視IOS的大小和傳輸速度。對(duì)于初次做IOS上傳,建議不要去修改什么傳輸速率。傳完以后 對(duì)整個(gè)系統(tǒng)初始化 界面如下: [nextpage]
