Cisco Infrastructure :: 3825 / ROMmon Password Recovery Not Working Properly?
Oct 30, 2011
We were unable to login to a 3825 with a known good password, so we used Cisco's Password Recovery Procedure for that device. We were successful in resetting the password, and had access to the CLI. However, when we logged out of the router, then attempted to log back in, the 'Invalid Password' prompt again came up.We have to use password recovery each and every time we need to access the CLI. Might this be an NVRAM problem?
Show version for this device is: C3825-advsecurityk9-m 12.4(3a).

I need to recover the passwords for my 3750 stack (2 switches), I have the password recovery documentation but it seems to be referring to recovery for one switch. How do I go about recovery when in a stack, should I remove the links on the switches and recover each one separately?Alternatively can I do a factory reset on them

I have a 4404 running firmware 7.0 and something happened (don't think it was a hack), but all of a sudden I can't login to the box via web or ssh or even telnet.
In trying the recovery procedure, I get a lot of messages scrolling through and cannot do the Restore-Password command on the CLI.
I'm attaching the whole capture, but here's a truncated capture from the procedure:
*fp_main_task: Nov 21 10:39:46.501: sshpmGetCID: comparing to row 0, CA cert >bsnOldDefaultCaCert<
*fp_main_task: Nov 21 10:39:46.501: sshpmGetCID: comparing to row 1, CA cert >bsnDefaultRootCaCert<
[Code].....
So as you can see, my prompt to enter the command is taken up by this fp_main message and it uses up the first and only time I can enter this in. I'm trying everything I can to not have to go back to factory defaults.

I have a Cisco 2960S-48FPD that someone was trying to do an upgrade, loaded c2960-lanbasek9-mz.150-2.SE2.bin instead of c2960-universalk9-mz.150-2.SE2.bin. To try and fix it they deleted both but before they could put the proper ios on, another person dropped power. Now the switch will boot into rommon, HOWEVER it won't respond to any keystrokes. It's stuck at "..... flash_init boot " and the switch: prompt. I have tried using both putty and SecureCRT, the settings are correct, the usb-serial works on another c2960S. I can read the output when it goes into rommon so it's not a baud rate issue.

We have a Cisco 3825 router which does not work well with a DSL modem(ISP provided). I have configured the Gi0/0 port of the router to plug into this DSL modem but it does not ping to the ISP gateway. If we do a shut/no shut on the interface then it work fine for about 30 secs. Sometimes even for 1 hr. Then the packets drop and we cannot pass any traffic through this interface.Now, if the ISP connection is terminated on a computer it works fine. It works fine without dropping any packet. I have tried various options like using a straight/cross cable. I have tried to configure the interface negotiation for 100/full, 100/half, auto/auto and almost all the options. I have also tried to interconnect the devices using a L2 device like a HUB. Nothing works.

I just bought one of these in and it was in production and I have no way of getting a hold of the login information. Is there a way to wipe these to factory defaults? I have been looking everywhere with no such luck.

I am a student pursuing a CCNA certification currently. I recently came across a lot of 3548 xl switches. They power up fine, post with out problem and load flash. The problem I am running into is that the console is password protected. I have found the password recovery procedure for this switch, but it requires the use of the mode button. I have tried this process several times and the flash file is loaded with the startup config file. How do I perform a password recovery on a switch with a broken mode button?

To configure my Cisco, I use the console cable but as I have no serial port on my PC, I use a USB to serial cable which I plug the console. I had lost this USB cable -> serial but I found another one. So I started to configure my Cisco by copying from an existing config. I found out that a prior the converter is defective and copy the wrong config.
I had copied the enable secret password and it badly copied! No luck, I made a copy run start. Therefore more accessible to Cisco! When I start the Cisco, I see what activated "the Mechanism password-recovery is enabled". so I followed the procedure Cisco
I go flash_init: OK but when I type "load_helper" Unknown command it say to me .... I'm stuck!
The model is my Cisco: Cisco WS-C2960G-24TS-S
SW Version 12.2(55)SE3
Sw image C2960S-UNIVERSALK9-M

I have a couple of 877s which have "no service password recovery" set and something has happened to the flash or the IOS has been lost for one reason or another.
When trying to boot the routers, they all display similar to this, which then repeats:
[code]....
Or words to the effect of there being no IOS at all, unable to boot, but the result is the same, it just loops and there's nothing I can do to break the sequence!
I've tried taking the flash from a working 877 and replacing the card but this doesn't work and unfortunately, putting the once working strataflash card back in the working 877, it gets the same problem!

I have a cisco 515e pix but where I bought it from did not get the machine back to default. I boot it up and get to the user prompt, type enable and it asks for a username and then a password. I am new to this and am have no problems with router and switch password recoverys but when I look at the cisco documentation it is a bit overwhelming and I am not quite sure what it is that they want me to do to fix this. I have downloaded all the password recovery software loads and have the one I need for 6.x which is what the box is running I am just not sure what it is that I need to do. Can I use that recovery software from directly from my pc using a tftp server?

I need to recover switch enable password, i have already configured AAA also, when i am tryig to follow below proceedure finally saying Authorization failed. how can i recover enable password,If I try to recover password like this description says [URL]
Step 1 Connect a terminal or PC with terminal-emulation software to the switch console port.
Step 2 Set the line speed on the emulation software to 9600 baud.
Step 3 Power off the switch. Reconnect the power cord to the switch and, within 15 seconds, press the Mode button while the System LED is still flashing green.
Base ethernet MAC Address: 00:0x:xx:xx:xx:xx
Xmodem file system is available.
The password-recovery mechanism is enabled.
The system has been interrupted prior to initializing the flash filesystem. The following commands will initialize the flash filesystem, and finish loading the operating system software:
flash_init
load_helper
boot
[code]....

I was just configured a 3800 router with this command. I cannot get to the ROMMON mode anymore. Cisco says you should press Break key within 5 seconds after the image decompresses during the boot. But mine is ignoring it and going to load running config directly.

I wanted to do with my Cisco 2800, a password recovery. I have read the instructions and Cisco just came up at six.
Complete these steps in order to recover your password:
Shut down the router. Remove the compact flash that is at the back of the router. Power on the router. Once the Rommon1> prompt appears, enter this command:
confreg 0x2142Insert the compact flash. Type reset.
BUT I had forgotten to plug the flash card. And now comes via console hieroglyphics only

I'm having problem on my 1841 it won't boot. No response on console but the led lights seems to be normal.I tried removing the CF then turn it on again to see if the router will go to rommon but didn't happen. I did try using another pc thinking the com1 is faulty but still no response on console nor rommon not showing up.

I am studying for the CCNA and have my own lab. Several months ago I setup the lab and hand things running well, and decided to put it all away for a while. Alas, now that I have brought it all out again, I don't remember the passwords I used and have since destroyed my documentation, so this is perfect practice at password recovery/config maintenance type of stuff.
I am working on a 2610XM. When I power on the router, I see all the information pasted below. I have tried the password recovery processes described in the cisco knowledge base where we use the rommon prompt to load 0x2142, reset, then enable secret <password> and followed the remainder of the instructions, but when I reload the router after the process, the new password I've set still does not work.
Some things that are not consistent from the documentation that I am seeing are the messages Slot is empty and WIC is empty.
I am wondering if my router does not use 0x2102 for it's load, but it will not show what it is using and I can't run show version because of the password. I am connecting through the console port and using putty to access and configure. Below is a paste of the startup messages after the router decompresses it's image.
Processor board ID JAD070709N9 (1997350087)
M860 processor: part number 5, mask 2
Bridging software.

I am trying to use the password recovery for an NME-16 and am having trouble. I am unable to look at my files in dir to so I can rename them. I can get the switch to bypass the config and come with the switch: prompt, but can not do anything more. I am trying the password recovery guide, but cant get to the text file to rename. I am using a 2811 router.

I purchased a Cisco 851 router from ebay a few weeks ago that has the "no service password-recovery" option enabled. I've tried every "break" option i could find, and this thing does not seem to let me get in. I asked the seller for the password, and they refused (though i cant even get to a prompt to enter a password) or ROMMON. The unit comes up and reports its trying to connect to "Translating "stipp.srv.hcvlny.cv.net"...domain server" once it comes up, and thats it. [code]

Recently I have bought a 2821 router from an auction. The router did have some configuration and password on it. I tried to break into it by restating it and pressing control and pause break signal. Old cisco method. Now when I try this method on my 2821. It does say that password recovery is disabled on the router. After this message router proceed with normal boot process. How to break the password ? Even if I loose the configuration.

I'm trying to do password recovery on a Catalyst 3850 switch..I've read the section in this: url...where it says that I need to have physical access to the switch (I do), and that I reset the password if I issue a break command and interrupt the boot procedure. I've tried to do that... it gives me the "switch:" prompt, so I think I've interrupted the boot procedure successfully, but, what do I do next?I've successfully done recoveries on Catalyst 2950s, 3550s & 3560s, but the procedure for this one, if I'm reading the link above right, sounds like it's completely different.
