# Cisco reset : 以 3750G 為例 ### [設定]: 1. 接上 Console 線啦,COM1 or COM2 看你自己的機器囉... ``` Terminal 設定如下: 9600 baud rate, No parity, 8 data bits, 1 stop bit, No flow control ``` 2. 拔掉電源線,並長按 "**mode**" button, 然後開機. 3. Type **flash_init** 4. Type **load_helper** 5. Type **dir flash:** #### 要確定 dir flash 後面有加 ":" 接下來應該會看到像下面的: ``` Directory of flash: 2 -rwx 843947 Mar 01 1993 00:02:18 C2900XL-h-mz-112.8-SA 4 drwx 3776 Mar 01 1993 01:23:24 html 66 -rwx 130 Jan 01 1970 00:01:19 env_vars 68 -rwx 1296 Mar 01 1993 06:55:51 config.text 1728000 bytes total (456704 bytes free) ``` 6. Type rename flash:config.text flash:config.old 將原來的 configuration file改名,如果接下來要乾淨的重新設定這台 switch 的話,那就直接把檔案殺了就好。 7. Type boot to boot the system. 8. Enter N at the prompt to start the Setup program, Continue with the configuration dialog? [yes/no] : N 9. At the switch prompt type en 進入特權模式( enable mode). 10. Type rename flash:config.old flash:config.text 將 configuration file 改回原始檔名. (如果還需要保留舊的設定時才需這個動作) 11. Copy the configuration file into memory: ``` Switch# copy flash:config.text system:running-config Source filename [config.text]? (press Return) Destination filename [running-config]? (press Return) The configuration file is now reloaded. ``` 12. 接下來就是重頭戲了,改密碼: ``` switch#configure terminal switch(config)#enable secret ooxx123 (其中 ooxx123 就是密碼啦,改成你要的) !-- This step is necessary if the switch had an enable secret password switch#(config)#^Z !--Control/Z ``` 13. Write the running configuration to the configuration file: ``` switch#write memory ``` 接下來就是做其他的基本設定 設備名稱、建立其他使用者、vlan、ssh、介面 ip 開啟 ssh 設定介面 一個對外 ip
