Bootup Router and then nothing

Hi,

I have a CISCO 1720 router, when I bootup the router my HyperTerminal Session runs through the system bootstrap and then goes to a rommon command line.

Here's a copy of the session output:

System Bootstrap Version 12.0(3)T, Release Software (fc1)
Copyright (c) 1999 by cisco Systems, Inc
C1700 platform with 32768 Kbytes of main memory

rommon 1 >

Has something happened to the memory on this thing? Maybe a power surge has knocked it out?

Can anyone shed any light on this or provide me with a solution?
All this on the very day that I am to have static IP's installed in my new house and utilise my CISCO Router...

Thanks!

Hi,
Your router is in the wrong mode. You need to change this by changing the conf-register to 0x2102

at the rommon prompt type in

config-reg 0x2102

reboot

If there are any errors you can get the correct syntax by typing ? at the rommon prompt the line number will go up on every line.

The way to get into rommon mode is by pressing the break key from Hyperterminal as the router is rebooting. So make sure you don't do this by accident. If you do just reboot by power cycling.

Your Startup Config should be unchanged, but you need to be very careful what you do in rommon mode it is easy to blat stuff.

Any changes you make once you get into the command (enable) mode should be saved by
copy running-config startup-config

Any problems just let me know.

good feed back would be much appreciated.

Carrie

The router starts and finish POST then decompress image file from flash memory then shows this message: System Bootstrap, Version 12.3(8r)T8, RELEASE SOFTWARE (fc1) Technical Support:...


I don't really know what your asking but i guess you want to know why your startup-config doesn't load. What your router is displaying is normal. You need to change the configuration register.
1.Let the router load then if asked select Yes to abandon autoinstall, then select No to skip initial setup. Press return (enter button) when asked.
2. Now type the following at the prompts. (you type the bold stuff press enter after each command)
router>enable
router#conf t
router(config)#config-register 0x2102
router(config)#exit
router#reload
........save changes blah blah blah.. type NO
continue with reload Yes
providing you have a startup-config, the router will now load it on bootup.

Hope this helps

I need to connect cisco 2800 router to my pc through hyperlink


I think you mean hyperterminal? you need a cisco serial cable (blue) and a serial port on your PC, maybe a USB to serial adapter if there isn't one. Set hyperterminal to use the COM port you have plugged in to, speed 9600 8 bit no parity. (8N1).
Without the serial cable you need to know the router IP and password.

Cisco 857 router


You might need to reset the password. In order to do this, follow these directions:

  1. Console into the router, then power cycle it. As its rebooting hit the "break | pause" button on your keyboard, and you get to the rommon1> prompt.
  2. Then type rommon1>confreg 2142 rommon2>reset
  3. The router comes back on as if it were new---answer no to the first question, and sometimes it asks a second question (do you want to terminate autoinstall, or something...)---answer yes to the secondquestion if it asks. Then hit enter and you get router> in a few seconds.
  4. Then router>en router#copy start run

create a new account:
  1. router#conf t
  2. router(config)#username bob priv 15 password bob
set register back:
  1. router(config)#confreg 0x2102
  2. router(config)#exit
  3. router#wr
  4. router#reboot

and that should let you login with bob/bob

I have cisco router 857 and dont know how to configure


Hi!
You can access the user manual for your router by going to:  http://www.cisco.com/en/US/docs/routers/access/800/850/software/configuration/guide/857sg_bk.pdf

But simply put,  - You have to enable the web interface in Hyperterminal/Telnet/Terminal - To connect to your router this way, open your Terminal and type the following commands in order:
1) enable (enter password if necc.) 2.) config term 3.) ip http server (this command might also be set to "no ip http server") 4.) exit
After doing the above: 1.) Press Cntrl+Z 2.) Go to Copy, Run, Start 3.) Open your browser and go to "10.10.10.1"
Good luck! -TJ

Cisco Router Boot Loop


you need to follow the steps to perform a password recovery on the router.
don'y actually perform the password recovery step, but you need to get a uncorrupted copy of the isos installed.

then try again.

I have assumed that when you power on the device you are able to see the boot process in hyperterminal, then just befor you get to type anything the unit reboots.

Boot Loop


you may have to reload the OS of the router.
i dont suppose you can kick it into romon mode can you? (usually done by hitting the pause break button on boot.)

if you can you should be able to use Xmodem to reload the OS (as long as you have a copy of it located on your computer)
