Cara reset password cisco switch
My practice using Cisco switch 2960, connect your console cable to the switch and open up your terminal emulator software, you can use hyperterminal on windows, putty or minicom if you are using Linux.
1. Enter to rommon
Power on the switch while holding the mode button. Release the mode button after you see the screen below in your terminal.
2. Initialize the flash file system
switch:flash_init
3. Find the config file in flash directory
switch:dir flash:
4. Rename or delete config.text
The files that we are looking for in the flash directory is the config.text, the password and configuration saved in config.text, therefore we need to rename or delete file config.text, if you still need config file, then it's better to rename
switch:rename flash:config.text flash:config.text.old
or
switch:delete flash:config.text
Rename or delete the config file so that it will not be loaded when we boot to the switch
5. Reload
switch:boot
After booting, the switch will ask you to enter the "initial configuration dialog" to initially configure the switch. Type the word "no" because we are not re-configuring the switch.
6. Back to rename
the configuration file to it's original filename
#rename flash:config.text.old flash:config.text
7. Copy and save the configuration file into the memory
#copy flash:config.text system:running-config
Now that the config is loaded in to the memory, we can start changing the password.
#conf t
(config)#enable secret newpassword
After changing the password, save the config and done.
#write memory
