I have a 3Com Router, Model 3030. What are the router commands used in that Router. I cannot use the following Commands: 1. sho version 2. sho interface 3. sho dsl int atm 0 4. sho ip route Are the commands in 3Com is different than Cisco Routers?

There are two main methods to return a Cisco router to its original factory defaults. These two methods are described below.
Method 1
1. uses the config-register 0x2102 command in global configuration mode.
2. Check the configuration register on the router by issuing the show version command.
3. The configuration register setting is displayed in the last line of the show version command output and should be set to 0x2102. If this is not the case, enter the config-register 0x2102 command once in global configuration mode.
router#configure terminal
router(config)#config-register 0x2102
router(config)#end
router#
4. If the show version command is issued again, the same line in the command output will have '(will be 0x2102 at next reload)' appended to the current register setting.
5. Erase the current start-up configuration on the router with the write erase command.
Reload the router with the reload command. When prompted to save the configuration, DO NOT save.
router#reload
System configuration has been modified. Save? [yes/no]: n
Proceed with reload? [confirm]
Once the router reloads, the System Configuration Dialog appears.
--- System Configuration Dialog ---
Would you like to enter the initial configuration dialog? [yes/no]:
The router is now reset to the original factory defaults.
Method 2
1. uses the config-register 0x2142 command in global configuration mode.
2. Enter the config-register 0x2142 command in global configuration mode.
router(config)#config-register 0x2142
This causes the router to ignore the start-up configuration on the next reload. If a show version is issued, the last line in the command output will have '(will be 0x2142 at next reload)' appended to the current configuration register setting.
3. Reload the router using the reload command in enable mode. It is not necessary to save when prompted to save the system configuration.
router#reload
System configuration has been modified. Save? [yes/no]: n
Proceed with reload? [confirm]
After the router has reloaded, the System Configuration Dialog appears.
4. Enter no to the question "Would you like to enter initial configuration dialog?"
5. Change the configuration register setting to 0x2102 by entering the config-register 0x2102 command once in global configuration mode.
6. Issue the write memory command in enable mode to overwrite the existing start-up configuration with the current running configuration.
7. Reload the router with the reload command in enable mode.
Once the router reloads, the System configuration Dialog appears.
--- System Configuration Dialog ---
Would you like to enter the initial configuration dialog? [yes/no]:
The router is now reset to the original factory defaults.
Note: The configurations below are stored in ROMMON, and cannot be reset to Factory Default Settings by the write erase or config-register 0x2142 commands.

Assigns a bridge group to the subinterface.
Note When the bridge-group command is
enabled, the following commands are
automatically enabled, and cannot be
disabled. If you disable these commands
you may experience an interruption in
wireless device communication.

bridge-group 1

Usually the software version of routers is called a firmware. You will need to download the latest frimware version from there website and upload it to your router through its configuration page.
You get to the configuration page through the routers ip address, usually its 192.168.1.1 or 192.168.0.1, you will need to type this into a web browser.

3. Configuring your Cisco Router If you have just turned on the router, it will be completely unconfigured. If it is already configured, you may want to view its current configuration. Even if it has not been previously configured, you should familiarize yourself with the show commands before beginning to configure the router. Enter privileged mode by issuing the command enable, then issue several show commands to see what they display. Remember, the command show ? will display all the showcommands aavailable in the current mode. Definately try out the following commands:
Router#show interfaces
Router#show ip protocols
Router#show ip route
Router#show ip arp When you enter privileged mode by using the command enable, you are in the top-level mode of privileged mode, also known in this document as "parent mode." It is in this top-level or parent mode that you can display most of the information about the router. As you now know, you do this with the show commands. Here you can learn the configuration of interfaces and whether they are up or down. You can display what IP protocols are in use, such as dynamic routing protocols. You can view the route and ARP tables, and these are just a few of the more important options.
As you configure the router, you will enter various sub-modes to set options, then return to the parent mode to display the results of your commands. You also return to the parent mode to enter other sub-modes. To return to the parent mode, you hit ctrl-z. This puts any commands you have just issued into affect, and returns you to parent mode.

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

Question mark is your best friend if you don't know when what commands you can type, but learning how to configure a cisco router is not a 2 minutes thing and 1 post is far not enough to tell you all about it. A list of commands won't do too much good for you anyway because there are 3 different modes and each has it's own commands and there are lots of commands.
If you want to learn the basics I suggest you to read their most basic book "CCENT/CCNA ICND 1"
Or try out their SDM, that way you can configure the router with good old fashion pushbuttons and check out the commands what it's sending to the router.

Here's a little bit of showaround about SDM:
If this isn't going to help you out I suggest you to post another question where you are specifically telling what you'd like to do and some expert will write down the commands, but you need to be very specific with the details of the network and the requirements and the services you need, wich routing protocol you'd like to use, etc...

from the login:
enable
configure terminal
router rip
version 2
network xxx.xxx.xxx.xxx

Hope this works for you.

you go to start, run, type cmd. and then type ipconfig. locate the ip for default gate way. Use the ip to go to your browser.

Here's a short summary of the steps to view the configuration. For lot's more details and other methods, refer to this online manual.
1. - Connect to router with computer using serial console cable
2. - Use Hyperterminal or other terminal program to communicate with the router
3. - Once you have access to the Command Line Interface, type in "display current-configuration" to view the configuration information text.
4. - Now you can copy and paste the configuration text to Word or Notepad to save or print.
