Cisco :: Recovering From ROMMON On ASA?
Jun 11, 2012
I cleared the flash (disk0) on my ASA and now I'm unable to restore it with an IOS.
When I attempt to load it with an IOS, it appears to load just fine. It even proceeds to restart, but when it boots back up it displays the error "No images in / Error 15: File not found. unable to boot an image" and goes to ROMMON.
My computer's IP is 10.0.0.1. I'm assigning the ASA 10.0.0.254. The image filename is asa724-k8.bin. Here's the output of the environmental variables and the attempted loading of the IOS:

Here iis a diagram of my current lab where I am using IP SLA to automatically switch from ISP 1 to ISP 2 should the connection go down (and vice versa)
My switches are C3550 Layer 3 switches. Both ISP's do work so connectivity is not the problem.
If I shutdown the fa0/19 port on SW1 the SLA kicks in and changes my defualt route out 10.0.1.0 without a problem. And when I do a no shut it comes back to tge 192.168.10.0 netowrk just as we would expect. No problem there.
When I disconnect the ISP 1 cell phone the SLA does switch the defualt route to the 10.0.1.0 netowrk. Okay, just fine so far. Here isthe problem, when i reconnect the cell phone the SLA does not come back to the 192.168.10.0 netowrk without first having to delete the SLA and then recresting it (both switches).

Recovering the password for a protected network.It can be difficult sometimes to recover a password for a home wireless network or a small to large business. There are several ways to recover such sensitive data and I would trust you to recover in all honesty for the sake and security of the business you work for or even your home network.So how do I recover the key if I don't know the gateway login to my router? the end user will likely default their router to recover the sensitive data but after defaulting they then realize that the SSID key has now been wiped out. The problem now is that all other trusted devices will be disconnected and the set up for the router; well that's just common sense, you would need to set up your static all over again (if applies) and your security as well. Use other devices in your house, trusted devices that have already been able to connect. Windows 7 is the protagonist in this role. Windows 7 enables the use of wireless profiles to be saved for faster connections to be made within the broadcasted range of the SSID. Btw SSID is the network name you see appear in your Wireless Manager. I.e.Bat_Cave; Starbucks; Barnes & Noble Wifi etc.
TIP #!
SSID - service set identification; two categories apply to SSID
SSID - basic service set identification
This applies to ad hoc wireless networks that do not have access points
SSID - extended service set identification
An infrastructure wireless network that has an access point; however this term can be used either SSID or eSSID. You will see eSSID with Point to Point; backhauls, switches, subscriber modules or comtrols; there are tons others but I won't stress other device types. Rarely will you connect to an AP, likely the type of service you receive depends on what you connect to, radio equipment like Canopy, Ubiquiti and Motorola are technologies you will see that are wireless based. What you are seeing is coming from a smaller device within your home or office network. If you use a Verizon air card, it's likely connecting to a nearby AP or a nearby radio which is pointing to an AP.Back to reality now, in order to locate profiles used in Windows 7 we head to the location by two categories of view in the control panel:
Small Icons Start > Control Panel > Network and Sharing > Manage Wireless Networks (This can be found in the left navigation within the vertical blue strip.)
Category Start > Control Panel > Network and Internet > Network and Sharing > Manage Wireless Networks (This can be found in the left navigation within the vertical blue strip.)
What you will see here may be a small list or a large list of every network you have connected to since you purchased the notebook. Now certificate trusted networks will appear here however they may not contain a key. The company I work for requires certificate of authentication and then the use of password linked to Active Directory as long as my computer is on the domain controller. Each wireless profile you see appear here has its own configuration and each configuration is bound to the SSID or network name. It's like the title of a book with its own story. You can have two (2) books with the same name but a different story. When I say different story, I am referring to a different encryption standard; cipher and wireless password. You can see below I have two (2) wireless networks with the same name but notice the different settings.
Bat_Cave
Standard: WPA2 Personal
Cipher: TKIP
Key: -pass51-
Bat_Cave
Standard: WPA Personal
Cipher: AES
Key: #Off5id35!
The reason I am showing you two (2) configurations is because when you are recovering a key for a network, you want to make sure the configuration is the same or else the door will always be locked until you correct your errors. The network name we have is Bat_Cave and we need to recover the key for the SSID that has a Cipher of TKIP.Right click the profile name and click properties. This will allow you to change SSID configuration on the notebook ONLY; in case changes have been made to the router or a buddy changed his encryption standard on his home network. Yeah it's easy enough just to remove the profile and reconnect; but that would be too easy, you wouldn't learn anything.Once you are in the properties of the wireless profile, click the [Security Tab] up top and you will see: encryption standard, cipher and the key; and as a plus, a check box to show you what the key is. Show the hidden contents and copy or write down the key.By using other trusted device on your network or business, you can utilize the resources that you have, to recover a password on your home or business network so long you have the permission from your superior and a good heart for positive intent.

it seems that i made a mistake when typing the BAUD rate of a 2960-Switch in rommon.I can't start the switch now, because there is no image on it (because I deleted it before) and the baud-rate has wrong settings. When connecting via console cable i can't see anything (except some strange hieroglyphics) when starting. I tried all the speeds in teraterm... without success.what can i do, to recover the switch back?

I'm trying to access the web setup page and I'm being asked for the user name and password. I have the password from the initial setup written down but apparently didn't also record the (changed) user name. It's not "admin" (tried that - and just leaving it blank - already).
Is there any way to recover the correct user name short of resetting the router and setting it up again from scratch?

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.

ASR 1004, has a image, which is on the harddrive, not bootflash and we have no boot commands in the configuration…We are running the ROMMON version ‘15_01rs’ The ASR boots into Rommon, as it cannot find a image (as expected), as the configuration has no boot commands.Trying to TFTP or getting an IOS back into bootflash is proving problematic.Follow all TFTP commands..
rommon 1 > IP_ADDRESS=10.1.1.1
rommon 2 > IP_SUBNET_MASK=255.255.255.0
rommon 3 > DEFAULT_GATEWAY=10.1.1.1

I'm having a little trouble with a router I have got my hands on to practice for my CCNA.Im connected via serial>USB adapter and via XP HT on Win7. Router boots and I then break the boot sequence with ctrl-break. But then it does not go into ROMMON mode. It simply says this:
-System Bootstrap, Version 5.2(8a), RELEASE SOFTWARE
-Copyright (c) 1986-1995 by cisco Systems
-2500 processor with 2048 Kbytes of main memory
How I get it into ROMMON to reset the password on it.

This question is about a Cisco 871, which has no bootable image in flash.The device is currently in rommon, and i am attempting to copy the correct .bin file over from usbflash0: but recieve the following error:unable to stat usbflash0:/: permission denied ?i get the same error if i try to boot from usb, or even try to view the directory.Config register is currently set to 0x2102? Typically in this scenario, i just boot from usb, and copy everything over in enable mode, but the lack of permission on this particular router has me stumped.

I'm trying to upgrade the ASR 1002 we just purchased and am having some issues (this is a new device and is not in service). I first tried upgrading the ROMMON using the upgrade rom-monitor filename bootflash:asr1000-rommon.150-1r.S.pkg all command, but the upgrade didn't seem to work completely. When I do a sh platform I get the below output showing 15.0(1r)S: [code]
no valid BOOT image foundFinal autoboot attempt from default boot device...Rommon upgrade requestedMaximum upgrade attempts exceeded, continuing with old Rommon...
I've also tried upgrading the IOS, but that is not working either. I tried "boot system flash:asr1000rp1-advipservicesk9.03.02.00.S.151-1.S.bin" command, but that did not work. I made sure the image was good using the "verify" command and made sure to set "config-register 0x2102". After I do a wr me and reload the router I get the below errors. [code]

Im trying to upgrade my IOS. It wasnt at ROMMON before but I thought I can upload the IOS on the xmodem so i did a
en
conf t
config 0x0
reset / reload
Now that I am in the ROMMON. If i type CONFREG to change the BAUD, nothing shows up. Usually it gives options but this time, nothing.
>confreg

So I tried to go back to the normal CLI

I turned on the router manually and turn it back on hoping that it will work but it brought me back to rommon.

I do not have a cross over cable and have to use xmodem. I set the baud rate to 115200 and I can see everything fine. Using Tera Term when you send the file via xmodem it freezes and closes on packet #3 or about 384 bits. When simply clicking the send file button you get the error-
*** Reserved LVL 7 Interrupt ***
PC = 0xfff0bc98, Vector = 0x500, SP = 0x80004c4c
Not sure what to do from here. I have tried everything.Error you get when you boot the router:

I have a Cat6506. There were 2 Sup 720 in it for redundancy. They told me they had problems with this thing in the past needing to go out and reboot the machine. I need to go out periodically because it goes into ROMMON. I type boot and it comes back up. One time though neither one would reboot. I had to take a third one out there and reconfigure it. Now it is starting to do the same thing. One thing I did notice is they never connected it to an UPS. It is plugged strait into the wall with power going to two outlets. I am beginning to think there are spikes in the power occurring and this is sending it into ROMMON.

we have 55 of the 1841 routers here, and one of them always boots to ROMMON from a very cold (down 1 hour or more) start. The image on all 55 is c1841-ipbasek9-mz.124-24.T4.bin. 32 MB Cisco brand flash. Here's what's been done thus far:In ROMMON changed to 0x2102. Then 'reset' and the image boots fine. Change config-reg to 0x2102. Save config. Reload and image boots fine again. Wait an hour or more and boots to ROMMON.Boot from ROMMON to USBflash0: Format the CF then copy over the bin file. Change to 0x2102 and save. Reload and image boots fine again. Wait an hour or more and boots to ROMMON.Swapped CF with another unit. Again, works fine to reload, but shut down and restart an hour or more later and boots to ROMMON. Format this CF and copy over image while on router. Image boots fine. Wait an hour or more and boots to ROMMON.In each case of very cold start the configuration register has reverted to 0x0 {why it boots to ROMMON}Tried dx mode with 0x8001. Nothing seen that is unusual to me, but I'm not an expert by any means.It doesn't seem to a CF card problem, but could be a connection to the CF card and then something behind that.
Here is the output of diagnostic boot mode:
Cisco 1841 (revision 7.0) with 116736K/14336K bytes of memory.
Processor board ID FTX1231W0JA
2 FastEthernet interfaces

DRAM configuration is 64 bits wide with parity disabled.

On new 1841 Testing Router, I deleted the flash & did the reload. After reloading, instantly I entered into the Rommon mode. I have a backup of the flash in my TFTP Server, which is connected to the 1841 Router. how can I restore my flash file into my 1841 Router. I can not get myself out of Rommon mode. I also now even can not ping the TFTP Server as well. Do I have to configure in the Rommon mode ?

I upgraded four 3560E, 12.2(44) to 12.2(55)SEThree 3560 works fine, the last one stops after 17-18 seconds with a solid green LED. I cant get into ROMmon, the switch doesn't boot up. its like "dead but still alive"
My TS:
1: Removed all SFPs.
2: Reset PSU and fan modules.
3: Replace PSU and fan modules.
4: Try to get into ROMmon.(pushing mode button and break seq.)
Startup LED:0-1 seconds: SYST: Amber RPS: Amber STAT: Green DUPLEX: Green SPEED: Green
1-17 seconds SYST: Blinking Green RPS: OFF STAT: OFF DUPLEX: OFF SPEED: OFF
18 s--> (only testet up to one hour) SYST: Solid Green RPS: OFF STAT: OFF DUPLEX: OFF SPEED: OFF
A working 3560EStartup LED information. If I compare a working switch with the faulty switch I can see about 18 seconds into bootingSYST change very fast from green to amber and continues with booting,this doesnt happened on the faulty switch (solid green 18 seconds). Pushing MODE button, doesn't get me in to ROMmon, this works for all the other switches.On a normal 3560 it takes around 40 seconds before I get in to ROMmon. With this faulty switch it stops after 18 seconds(solid green) and it doesnt respond.

I have a rare case. switch 6500 make crash and go to rommon. when review the crash appear that the switch charge the configuration from nvram, but, at the ending there are a few line command, that make the switch go to crash.. then I have to booting from rommon and start again. I use the version 12.2.33.sxi9 and 12.2.sxi3 and the configregister is 0x2102
I think that the switch get the startup-config file from other file-system.
