View 3 RepliesI'm currently pursuing to take my CCNA and am currently studying for it, but have recently encountered a problem with one of my 1760 routers that I can not solve.Yesterday I went to boot up my router like normal, however when I went into hyperterminal I noticed the router was in Rommon mode. Thinking I could change the configuration registry, I tried to bypass the NVRAM by using confreg 0x2142. However this still causes the router to go into Rommon mode. I am getting an error that states that there is insufficient memory to load the IOS image. [code]
I have used the dir flash: command and can see the IOS image, and try to boot from it (boot flash:iosimagename) but it will still go back into rommon mode. I also just swapped the RAM from my other 1760 into this 1760 and it booted up and went into normal configuraiton mode without any issues. However, the other router now will not load it's IOS image and I get the exact same error.I'm at a loss here, and have searched to figure out where or how I can just wipe the router clean to try and start fresh, but cannot get out or Rommon mode. The only thing I can think of is that the RAM went bad since it wont boot up either machine.
I have 6509 E. Actually what happen it last 3-4 times it reload its self and got stuck in rommon mode, i tried to boot it with boot by connecting a console cable on supervisor 720 2b. What and where is problem and why is stuck in rommon after reload.

The problem is the switches interface never comes up so try to connect to the tftp server. I read on google it can't be done on a switch to copy from tftp to flash in rommon mode on a switch and to use XMODEM. My problem is I do not have access to it, I ssh into a 3640 which is an access server for all devices and that is how I have console to it, how to use XMODEM over ssh.
But I'm fairly certain that there has to be a way to just copy it from tftp? I have a 3550 local and when I put it in rommon mode it stops the port check at port, port 1 goes from green when you plug it in to off then port 2 changes to amber and the rest green. So just by the look of this I would believe tftp would work; you just need to use port 1.
We have a cisco catalyst 6509 with Supervisor Engine . After power outage, the switch always start in Rommon mode. Configuration register is 0X2102, we want to it always start in normal mode. What should i do?

View 1 Replies View RelatedI have an issue with a customers 6503 with Sup-2T cards, where we are locked out of the console due to an authentication configuration error. So tried several times to get the card into rommon, with no success.
Checking through the various documents on CCO I dont find any reference to rommon on this card, but do find information on using the CMP to support the supervisor. I logged into the CMP but couldn't find a way from there to do a password reccovery either.So, is the `normal' IOS rommon/password recovery method supported.
My company has a Cisco IAD 2400 which is handling our phones and the internet (from Service Provider). We are adding a second router, a Cisco 1921, to our network,I think I have everything set up correctly. One department is using the 192.168.2.0/27 subnet. I can ping each computer within that subnet. Also, within this subnet, I can ping the router interface at 192.168.2.1. I can ping 192.168.1.2 successfully as well. This is the interface on the 1921 that goes to the 2400. However, if I try to ping 192.168.1.1 (interface on 2400), I get "Reply From 192.168.1.236: Destination Host Unreachable" I get the same thing if I ping 8.8.8.8.Within the 1921, I can ping 192.168.1.1 and 74.125.224.72 (random google ip) successfully.

And the same message is prompted.
I try to recover password by following the recovery procedure. After the boot command, I never see the message "Continue with the configuration dialog? [yes/no]: ".
I have 2691 router with following config

When i remove the login local from the line console i connect to console port and press enter it shows router prompt 2691Router> but i am unable to go to enable mode.If i telnet to router then i put username and pw then it goes straight to enable mode.
vty config is

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 ?
how to restore the flash image via TFTP Server on my 1841 Router.
I upgrade to a Flash 32mbs memory stick, as I reboot the 2600 Cisco router, it appear in the ROMMON mode, nonetheless, I followed some wrong procedure by changing components on the ROMMON command line. however now the router reboot or start with symbol only V2V2v2a, and I can no longer enter the ROMMON Mode or key anything in. I have a copy of the IOS on my TFTP server.

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.

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.

Is it possible to use the mgmt port when in rommon mode? I use the Mgmt port when IOS is loaded and it works fine.

i try to recover cisco ASA 5505 IOS in Rommon mode but i have this message : [code]
View 1 Replies View RelatedI have one problem in my Client end router cisco 1841.
Everyday we switch on the router it will automatically goes to ROMMON mode.
So i take remotly and check wheather the IOS is corrupted or not.
So i use the command dir flash: to check IOS is available or not. i found the IOS is there.But it is not boot from IOS.
So i use the coomand boot xxxx.bin to boot from IOS.and finally it booted.
They told to use the coomand confreg in the ROMMON mode.
I am facing a problem with a cisco 6509 that goes into rommon every time i restart. If i give the command
rommon 1> boot
it will pick up the IOS on the sup-bootdisk: or bootdisk: and boots up but i dont understand why on reboot it wont pick up this IOS and boot itself and why do i have to write boot command everytime on rommon.
I have also explicitly given the command "boot system bootdisk:IOSNAME.bin" in the startup config file but still no luck.
An ASA 5505. Device boots to rommon #0> and stays there. The complete boot record follows:

How can i Upgrade Catalyst 2960 switch software in Rommon mode (switch:)
Right now flash is empty.
Yesterday I tried to install c2960-lanbasek9.mz.12.55.SE4.bin onto my router. When I changed the boot commands, I did not leave the 2nd option in there and the old firmware has an .ex3 extension. After trying to boot to this new image, we receive a looping error message that continues to reboot and go through the same process.Basically the error is "ERROR: firmware not supported by hardware"I have power cycled it a few times but durning bootup, I never see the ################## which would allow me to BREAK sequence and get into rommon. The device simply waits about 30-40 seconds after boot and goes right back to the looping reboot sequence and the error message. Is there any hyper term or putty settings to change on this?
View 1 Replies View RelatedWe have some 4510R+E with dual sup 7e that have experienced problems recently. One of the sup 7e's crashed with a "critical software exception":
#show verCisco IOS Software, IOS-XE Software, Catalyst 4500 L3 Switch Software (cat4500e-UNIVERSALK9-M), Version 03.01.01.SG RELEASE SOFTWARE (fc1)
<snip>
ROM: 15.0(1r)SG1
<snip> Last reload reason: Critical software exception, check bootflash:crashinfo_iosd
So I thought I'd upgrade to IOS-XE 3.2.0SG to hopefully resolve the issue. I was reading the software release notes and it says:
If you are upgrading to 3.2.0SG, you must upgrade your ROMMON to 15.0(1r)SG2.If they have dual supervisors, first upgrade your software to 3.2.0SG, then upgrade your ROMMON to15.0(1r)SG2 to avoid the resets uplinks issue (CSCtj54375).
And from the ROMMON release notes it says:
Download the cat4500+e-promupgrade-150_1r_SG2 program from Cisco.com, and place it on a TFTPserver in a directory that is accessible from the switch that is upgraded.The cat4500+e-promupgrade-150_1r_SG2 program is available on Cisco.com at the same location from which Catalyst 4500 system images are downloaded.
So I have several questions:
The only promupgrade file I can find is cat4500-e-ios-promupgrade-150-1r-SG2 (which doesn't appear to be the same as cat4500+e-promupgrade-150_1r_SG2 ). Where the correct file is?Since I have dual supervisors, it says I should upgrade the software, then the ROMMON. If I can do that (run the new software with the old ROMMON) why am I bothering to upgrade the ROMMON in the first place? (update, ok, I see the new ROMMON gives me enhanced crash info and will allow future upgrades without bringing down both supervisors at the same time).When these were ordered/installed, the licenses were all mixed up (I wasn't involved with that ). So the MDFs have dual sup 7e with ipbase and the IDFs have single sup 7e with enterprise services. Obviously, we want the enterprise services in the MDF so we can run OSPF and the ipbase in the IDF. But, OSPF seems to be running just fine in the MDF on ipbase. Are the licenses not enforced on these platforms? The release notes for 3.2.0 say ipbase doesn't support OSPF. So if I upgrade the MDF switches, will OSPF suddenly stop working?
The IP Base image does not support enhanced routing features such as Nonstop Forwarding (NSF) , BGP, Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), Intermediate System-to-Intermediate System (IS-IS), Virtual Routing Forwarding (VRF-lite) and policy-based routing (PBR).
