Router- Rommon
Hi
I have router stuck in Rommon, i tried to upload new image, but show to me message
"all existing data in all partitions on flash will be lost"
So, should i proceed, or is there any other method be more safe i can use..
Thank you
Hi
Router is 2800 series, it is 64 MB it was stuck to rommon suddenly, for that reason i tried to upload image steps like following:-
rommon 16 > IP_ADDRESS=171.68.171.0
rommon 17 > IP_SUBNET_MASK=255.255.254.0
rommon 18 > DEFAULT_GATEWAY=171.68.170.3
rommon 19 > TFTP_SERVER=171.69.1.129
rommon 20 > TFTP_FILE=c2600-is-mz.113-2.0.3.Q
rommon 21 > tftpdnld
IP_ADDRESS: 171.68.171.0

TFTP_SERVER: 171.69.1.129
TFTP_FILE: c2600-is-mz.113-2.0.3.Q
Invoke this command for disaster recovery only.
WARNING: all existing data in all partitions on flash will be lost!
I do not know if there other method than this?
Thank you

Router ROMMON upgrade - your opinions
Hello,
I've read in several documents that there is only a need to upgrade ROMMON if there are new features in new ROMMON versions.But, e.g. the ROMMON upgrades for the Cisco 2800 platform, the changelog for 12.4(13r)T5 says "Enhancement for device access in certain Cisco routers.",
12.4(13r)T6 says "DRAM access optimization" and 12.4(13r)T11 says "write/erase timeout increase + status read changes".
Or with the Cisco 2900 platform, the changelog for 15.0(1r)M10 says:
Saving of IOS config sometimes fails on some 2900s (Fix in ROMMON)
- Bootflash access timing parameter change.
Compact Flash timing parameter changes (ROMMON)
- Compact flash access timing parameter change.
I think the bug "Saving of IOS config sometimes fails" is not a small one. And I don't know what "DRAM access optimization" or "write/erase timeout increase + status read changes" exactly does.
Is it still true to upgrade ROMMON just in case there are new features which are needed. Or should the ROMMON be upgraded just as the IOS if a new version with fixes is available?

Just like with IOS upgrades, generally most would upgrade if there's a new feature or bug fix that pertains to you. When neither is true, most prefer to not upgrade; "it ain't broke, don't fix it".
Consider many software releases are for bug fixes, so although you might not have bumped into a known defect, you may. This would argue for upgrading all maintenance fixes. However, sometimes, maintenance for defects introduces other defects. This argues only do an upgrade if operationally necessary.
So, whether it's an IOS or ROMMON upgrade, it's really what you think is best.
PS:
BTW, for some platforms like the 2800, I recall an effective ROMMON update would force an immediate reload, unlike a IOS upgrade which can be loaded onto flash and the reload scheduled for later. (Suspect this is why Leo insures there's a new IOS on the 2800 before he does the ROMMON upgrade.) -

Trying to Download a Software Image to Cisco 2800 series router through TFTP Using the tftpdnld ROMmon Command
and I am getting an Error , I cant figure out what I am doing wrong. I have also pasted my display down here can someone help me out, thanks in advance, I am still new to this utility.
My questions are How do you direct this utility to point to the desktop or the TFTP folder
does FE_PORT: Fast Ethernet 0 imply or point to Fa0/0 on my router
My router is suppose to have 10.0.0.3 255.0.0.0
Gateway of 10.0.0.1 255.0.0.0
My TFTP Server 10.0.0.2 255.0.0.0
How do I get the MAC address of the Router or the TFTP Server and which one is required?
my Ethernet port is 100Mb/Sec I cant tell whether it is full duplex or not so How do i set this FE_SPEED_MODE: Auto???

which says that the router is looking for the 10.0.0.2 server but not getting response to its arp request. Can the original poster clarify for us how the device that has the image file is connected to the router that has the problem? Also what kind of device is 10.0.0.2? Is it a PC running TFTP server software or is it something else?

Cisco 1760 router stays in rommon modus
I am having problems with a cisco 1760 router. When I turn the router on I am getting stuck in rommon mode. When I enter the command: "boot flash:c1700-sv8y7-mz.123-11.T3.bin" , the router will boot the ios image. But when i turn the router off and on, it will return to rommon mode. I have tried the following commands in rommon mode:
rommon 1 > confreg 0x2102
rommon 2 > reset
or
rommon 1 > confreg 0x142
rommon 2 > reset
without results. I get the following errors:

Thanks,
PieterI would recommend posting in the netpro forums about this.
http://www.cisco.com/go/netpro
This site is for the Cisco Small Business Pro routers.
For your problem though, you might try looking at your boot system command in your running config to make sure that it is accurate. -
I have a 7606-s router, it is stuck in rommon, it can't find the ios, i can't even download ios to it via xmodem.can anyone help? please...
Thanks Leo for replay
Following RP crash info taken from bootflash, it is very helpful if we can find the related bug details.

ROMMON Password Recovery for 803 Router
Hello Netpros.
Whilst attempting to perform a standard enable password recovery on an 803 router, I discovered that a ROMMON password had been set. This had the significant disadvantage in that I could not set the config register to bypass the configuration on startup using the set command.
I've browsed Google and this site and there seems to be some reference to a cookie and/or priv command that may assist with resetting a ROMMON password but this particular router does not seem to understand either of these commands whilst in disable mode.
Excerpt follows:

AdrianHi,
Yes, if you get this boot prompt with the ">" and not "#" that means some joker set a ROMMON password without reading the documentation what is the impact of that (and not documenting it as well). You have to contact Cisco TAC to clear that password, it's not written in any documentation how to clear it.

Router opens ONLY ROMMON??!!
Hello,
I have a problem i need help with, i got i cisco 2600 series router recently which is used,when i first started it ,the console screen goes only to ROMMON and can't boot from the IOS image, this is what iam getting : and i also wanna make sure that this is not because this is no flash and/or NVRAM in the device installed so i looked up a picture for the back of it online and it looks just like mine so i thought this is normal i attched this picture here with this message...Any ideas?
Thank you.

Router 2600 & stacked in ROMMON option !
Hello every one,
I have got 2 cisco routers 2600 series and I am only using them for practicing my CCNA, when I changed the passwords on them, after a few days I didn't log in to one of them and as a result I forgot the password whcih resulted me ending in "rommon" option, after following the password recovery procedures but I was not able to get through of the complete process of the steps in recovering the password and when I was in half way through the recovery process it was suddenly stopped and then I had to turn it off and back again because it was jamed and I had not any other option. I was advised by some friends that I had to reload my router the operating system.
Now, my problem is that I have not been able to install the IOS image from my other router to this router that I have problem with. I have never done it before and I would appreciate your help and assistance if you could explain to me in some easy and clear steps of how to instal it.
Note: The router that I have got problem with is in it's rommon option only and it does not accept any sort of command.This time it reloaded it as I did the below but still could not change the password:
rommon 3 > confreg 0x2102
You must reset or power cycle for new config to take effect
rommon 4 > reset

2851 Router will not boot from CF, after reload goes into rommon
I recently obtained a 2851 and have been battling this issue for a week now. An odd set of circumstances happen with the bootstrap startup process. If the router has loss of power or when reloaded; it fails to read the CF card and boots to rommon. I can tftp an image to it (tftpdnld -r) and IOS CAN read the flash card along with any saved configuration.
In fact once in IOS, I can wr mem and print the hardware details of the CF card. Once I reload the router it goes to rommon, fails to open the flash, then sits until i tftp the image back. When the router load IOS, it also loads the startup config.
I don't think it's a problem with the CF card as IOS can read it. I've tried formatting the card from IOS and from my pc as FAT, FAT16, FAT32, and NTFS - it didn't make a different. I updated the ROMMON to allow for USB booting but haven't purchased a USB Drive yet for testing. The upgrade didn't resolve this issue either. It almost seems like a firmware problem with the EPROM.
I've played with the config register to see what, if any, impact it had. Currently it's set to 0x2102, putting it in the diag register didn't produce any other errors than what's listed below.
I'm stumped and out of ideas. Hoping somebody has some insight on what could be causing this to happen.
Apprecite your time reading my question.

I added boot system statements to the config to cf, then usb0, then usb1 to see if perhaps one would read. It looks like it doesn't bother after the first device fails. This is only for my studies and I can deal with "tftpdnld -r" every time I boot it. Just was trying to nail down any other possibilies.

just seems to always boot back to the original file and not the one i just tftp'd up. could it be that this router requires additional ram to support this ios?
file that i tftp'd to flash was
c181x-adventerprisek9-mz.151-4.M3.binJohnathan,
When you say your are "telling" your router to boot to the new file and it is not, when it does boot do you see any errors listed during the boot-up sequence?
Based on your comments can I assume you have a command in your configuration file that looks something like the following:
boot system flash:c181x-adventerprisek9-mz.151-4.M3.bin or at least something along these lines?
If you have two bin files in your flash, the router will boot to the first one it sees listed consistantly. if the new bin file is the last in line, it will never be called to load.
If you are concerned about not having a working bin file to fall back onto, then save your working bin file to a tftp location. As a minimum if the router has issues with your new bin file, it will boot to rommon and you can get the working bin file back into the router from there. If you had memory limitations, you would have received an error of some sort during the tftp'ing of the new bin file that there was not enough room. Have you done an MD5 check to see if the bin file did infact transfer sucessfully?

CTRL+break doesn't work, cannot boot on Rommon.
GoodDay to All,
Im using a 1750 router, and then i upgrade it to higher version, after
then i reload it, the problem it does not goes to start-up mode or
even the rommon mode,not enough memory to load the image, it always
rebooted after the self-decompressing image,
I try to stop it using the CTRL+Break, but it doesn't work.
Here are the error message.
Smart Init is disabled. IOMEM set to: 20
Memory required: 31637548 bytes, Memory available: 25165824 bytes
INSUFFICIENT MEMORY TO LOAD IMAGE!
The difference between Memory required and Memory available is the additional
memory you need to run the router. Alternately, use a smaller image; this
may cause the memory requirement to decrease, and may allow you to at least
use the router with reduced functionality until you get more memory.

Thanks,
LesterHi Lester,
After trying all the above suggestions, if you still are facing issues then open the router's box and take out the Flash SIMM... it will try to look for an IOS file thrice and then will fall into rommon automatically
You can use the following link for hardware installation:
http://www.cisco.com/en/US/customer/products/hw/routers/ps221/prod_configuration_guide09186a0080099429.html#wp1077820
After you are in rommon, issue the command "confreg 0x2100" and "reset" the router, you will again go into rommon
Then insert the FLash once again in the chassis and then bootup again, because of config-register 0x2100, the router will go to rommon and then you should check the new IOS that you are trying to install.
Your router should have sufficient amount of DRAM to load that IOS, infact it'll help if you post the exact file names of the previous IOS and the new IOS along with your routers DRAM and Flash Capacity (But this is a secondary task which we can think of once you are able to go into rommon)

hi!
i dont know if it's the correct forum but i got a simple question that i would like to be answered.
Recently i brought a 877 adsl router with the advance security ios. I thought this ios supported 802.1q, but i don't think so. So i upgraded to advance ip services ios. This ios support 802.1q and vlan implementation. The router seems to work fine. Everything was configured through CLI.
My question: This upgrade can cause some kind of problem with router functionality? if so, which ones?
The configuration is very simple: no vpns and basic firewall configuration.
Thanks for your help.Hi there,
IOS Upgrades Dont affect Router Functionality BUT the features available on the Device.
Min Flash Requirement is There as BackUp Images are Recommended. In case The New Image is Corrupt or things dont go as planned, We can Manually boot the Router from Rommon.
Its a Standard Practice in Production Environment so as to Maximize Uptime.
Regarding the Features Required the best Pactice is to Use Cisco Feature Navigator
