Re: cisco 857 router
You might need to reset the password. In order to do this, follow these directions:
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.
Then type rommon1>confreg 2142 rommon2>reset
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.

When the router first starts booting you need keep hitting the break sequence which should be crtl+F6 and that should bring you to ROMMON mode. you should get a prompt rommon 1>, that means you did it right. Now you need to change the configuration registers to 0x2142 by typing "confreg 0x2142". then type reset to restart the router. It should now ignore the saved config. hit crtl+c to cancel the initial setup, type "enable" to get to the enable prompt. Next type "copy startup-config running-config" to copy the startup configuration to the running configuration. Next type "configure terminal" to enter global configuration mode. Now you can type "enable secret <password>" to change the password to what you want. Last you need to change the config registers back to 0x2102 by entering the command config-register 0x2102.
Follow these steps in order to recover your password:
Attach a terminal or PC with terminal emulation to the console port of the router. Use these terminal settings:
9600 baud rate
8 data bits
1 stop bit
No flow control
If you can access the router, type show version at the prompt, and record the configuration register setting. Note: The configuration register is usually set to 0x2102 or 0x102. If you can no longer access the router (because of a lost login or TACACS password), you can safely assume that your configuration register is set to 0x2102.
Use the power switch in order to turn off the router, and then turn the router back on. Important Notes:
In order to simulate this step on a Cisco 6400, pull out and then plug in the Node Route Processor (NRP) or Node Switch Processor (NSP) card.
In order to simulate this step on a Cisco 6x00 with NI-2, pull out and then plug in the NI-2 card.
Type confreg 0x2142 at the rommon 1> prompt in order to boot from Flash. This step bypasses the startup configuration where the passwords are stored.
Type reset at the rommon 2> prompt. The router reboots, but ignores the saved configuration.
Type no after each setup question, or press Ctrl-C in order to skip the initial setup procedure.
Type enable at the Router> prompt. You are in enable mode and should see the Router# prompt.
Type configure memory or copy startup-config running-config in order to copy the nonvolatile RAM (NVRAM) into memory. Important: Do not type copy running-config startup-config or write. These commands erase your startup configuration.
Type show running-config. The show running-config command shows the configuration of the router. In this configuration, the shutdown command appears under all interfaces, which indicates all interfaces are currently shut down. In addition, the passwords (enable password, enable secret, vty, console passwords) are in either an encrypted or unencrypted format. You can reuse unencrypted passwords. You must change encrypted passwords to a new password.
Type configure terminal. The hostname(config)# prompt appears.
Type enable secret password
> in order to change the enable secret password. For example: hostname(config)#enable secret cisco
Issue the no shutdown command on every interface that you use. If you issue a show ip interface brief command in privilege EXEC mode, every interface that you want to use should display up up. For example: Router#show ip interface brief
Type config-register configuration_register_setting>. Where configuration_register_settingis either the value you recorded in step 2 or0x2102. For example: hostname(config)#config-register 0x2102
Press Ctrl-z or end in order to leave the configuration mode. The hostname# prompt appears.
Type write memory or copy running-config startup-config in order to commit the changes.
connect the blue cisco cable to the console port of the router concerned. Then using a pc based terminal emulator such has hyperterminal or putty (download using a google search), login into the router. when in privileged exec mode, type the following command, show running-config, or wr term or sh run and you will get to view the configuration.
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.
hey you are saying that you want to configure the router,, but rommon mode is for breaking the password....do u forget the password of the router......can you explain why u need to log in through rommon mode
You can access the user manual for your router by going to:
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")
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"
