I am selecting a router, let's say to be used as a VoIP Gateway (C3945 + PRI ports).If I order the "Security license" included (bundle C3945-VSEC/K9), what is the benefit of getting the security license for a gateway router? Today in the organization we don't see an immediate application for the security license, but I would like some feedback on ways that it could benefit the organization if future security policies are implemented in the future.

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:

How I get it into ROMMON to reset the password on it.
Im trying to get into Rommon, Im reading thats the BREAK button, which im assuming obviously its the pause/break button on my keyboard, im pressing it till my finger turns blue a billion times and still no rommon noodles for me.

I 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 have a problem with 1841 router - It wont't boot up and there is a message
Correcting primary nv_flash
I have a 2621 router, because I want an image of about 21M, I upgraded as follows:
IOS = 32M
RAM = 64M
ROM VERSION = 12.2
However, when I power up my router, it goes into a boot loop, and I see the following messages:
NOT ENOUGH MEMORY IN THE SYSTEM TO RUN THIS IMAGE
***SYSTEM RECEIVED A SOFTWARE FORCED CRASH***
how to overcome this error, and successfully upgrade, so I could load my new image?
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.

View 1 Replies View RelatedI've got a 2621XM that has not been used for a while.Completely stripped of any modules and configuration files, the router will continually cycle the startup process without actually booting from the IOS.
The cycle displays the following :

What I've tried:
1) Downloading another IOS image (c2600-is-mz.123-20.bin) via Xmodem and running "confreg 0x2102" from the rommon. All that did is change the last message to "program load complete, entry point: 0x80008000, size: 0x10fa95c"
2) Running the command "boot flash:c2600-is-mz.123-20.bin". If I enable the diagnostics via rommon, the cycle expands to:

If it wasn't for the lack of error messages, I would assume it was a hardware issue.If the image was corrupted, I would expect a message indicating that the image couldn't be read.
I've had a Belkin N+ wireless router for about 5 months. I reset the router recently (using the reset option on the router itself) and now it doesn't boot up. The lights at the front flash as if its going through its boot sequence but it never stops. I left it for 2 hours while I went out and when I came back it was still going through the boot sequence.

After 17+ minutes the boot is complete with the correct full image.

I know you can get a 24MB upgrade card but they are quite expensive.
I have a 2 computers connected to a Linksys BEFSR41 router which is connected to a Verizon Westell DSL/Cable modem. From time to time the Ethernet link between the modem and the router spontaneously disconnects. I can reconnect the link by going to the setup menu on the router with a browser @ 192.168.1.1 Sometimes I have to do an ipconfig/release and renew to fix the link. Sometimes I have to power cycle the PC and the modem and the router.Currently this disconnect problem has gotten much worse. It occurs about every 15-20 minutes while I'm connected to the net. It also occurs when either computer is booted or turned off (I see the link light on both the modem and the router flash red for a moment).

Since the restart it has never stopped cycling the boot sequence without end. The download lights cycle and the router light flashes constantly. And I am unable to connect to the router page at 192.168.2.1 So I cannot reset the router, the hardware reset button just momentarily pauses the endless booting process.

View 7 Replies View RelatedLast night we had some pretty bad lightning and thunder and our Linksys WAG160N appears to have had a bit of a fright.As I was going round unplugging items in case of a hit (this was after a flash or two, relatively nearby), all the lights on the router were off except for the ethernet light (plugged into a Linksys homeplug adaptor). Now the router doesn't appear to boot. When powered on, the power light doesn't flash or anything to indicate booting up, all you get is the ethernet light (if connected) after a few seconds, but no activity. I'm presuming something has been fried or corrupted? I'm not sure if we did have a power spike either through the mains or phone line as all other equipment seems to be fine, but I'm wondering the the homeplug connection might of had something to do with it after reading a few posts from others on the subject.I've held in the reset button while starting and it doesn't appear to have done anything. I will try the 30/30/30 reset tonight.
