Cisco 3925 Router Password Recovery


The Cisco 3925 router is part of a family of networking equipment produced by Cisco, which has been a network equipment giant for many years. Used 3925 routers are available on the Internet at reasonable prices, so acquiring one is not difficult. However, if the password is unknown or lost, reconfiguration is impossible until the password is reset or recovered. Cisco has built in a procedure for rescuing lost or forgotten passwords or entering new passwords.

Things You'll Need: Serial to RJ-45 cable; Terminal emulation software

Instructions
1. Connect your computer to the router with the blue serial-to-RJ-45 cable that came with the router. The 9-pin D-shell end connects to your computer's serial port, while the RJ-45 end connects to the console jack on the router. The RJ-45 end resembles a slightly larger telephone jack connector.

2. Turn on your computer and establish a terminal session to the cisco 3825. You can use any terminal emulator, and many are freely available on the Internet. Configure the session settings as follows:
9600 baud
8 data bits
No parity
1 stop bit
No flow control

Plug the router's power cable into an electrical outlet, and as the cisco 3945 boots, you should see the Cisco boot messages. If you don't see any output on your computer's terminal session, check your settings on the session and restart it if necessary. Press "Break" within 30 seconds of powering on the router to enter rommon (rom monitor) mode.

3. Type "confreg 0x2142" and press "Enter" at the "rommon 1" prompt. This will cause the router to boot from its internal flash memory without loading the configuration into memory. At the following "rommon 2" prompt, router cisco type "reset" and press "Enter." This will cause the router to reload and ignore the previously saved configuration file.

4. Respond "no" and press "Enter" when prompted for responses to enter the initial dialog or basic management setup. Type "enable" and press "Enter" at the following "Router>" prompt. This will put you into enable mode and display the "Router#" prompts. Copy the non-volatile memory into memory with the "copy startup-config running-config" command, followed by the "Enter" key. buy cisco router Type "sho run" at the prompt and press "Enter" to display the current configuration, including the passwords, some of which may be encrypted.

5. Type "config t" at the prompt and press "Enter." At the "Router(config)#" prompt, type "enable secret <pswd>" -- where "pswd" is the password -- and press "Enter." At this point, your enable password is reset. Press "Ctrl" + "z" to return to the "Router#" prompt.

6. Type "config t" at the "Router#" prompts and presses "Enter." At the "Router(config)#" prompt, type "config-register 0x02102" and press "Enter" to reset the boot register to its normal setting. buy cisco routers Press "Ctrl" + "z" to leave configuration mode. Type "copy running-config startup-config" and press "Enter" to save your changes. Reboot the router and you should be able to login with your password.
