I have found in my limited travels on this earth that different approaches work for different people. The key is to reach as many people as possible. Here's a further logical extension of the analogy: Routers are like people too :-) You can extend the analogy to the startup-config. It is similar to your conscience/morality. You get it initially with a clear slate (router of the box). From there you can be programmed by others to do good (or not), depending upon how you are raised/configured. Unlike humans however, we cannot do an "erase startup-config" for those with bad programming ;-) HTH, Paul Werner Get your own "800" number - Free Free voicemail, fax, email, and a lot more http://www.ureach.com/reg/tag _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
RE: Router w/o any brains
Paul, This really makes my week. I love analogy and the one you have written is totally awesome. I would like to use it if you do not mind. Have a great weekend...

Is this true? Boot mode is what he called it. Any help is much appreciated in advance.< While I am reasonably confident that this issue has been addressed at least one hundred times in the archives, I am going to take a new and innovative approach on this issue. Here goes... Consider your router to be like a little kid. It generally has no intelligence until you take the time to educate it. It will function without education, but it does so much better with a little bit of intelligence turned on. Consider that you have the ability to influence the intelligence of this router and restrict whether it will remain at the fifth grade level, or advance on to doctoral studies in network engineering 8-) First, you will need to turn on the "proper" learning environment. You do this by going to the proper mode on this device and first determine if it has a brain. Sadly alas, not all routers have brains installed! Some of them have lost their brains along the way due to maliciousness on the part of others, abandonment, or neglect. Sometimes, they have to get their brains every time they wake up (it's a difficult life for a router). If they can't find their brains, they wander aimlessly through router life as an uneducated router. To check to see if the router has any brains, do a "show flash" command when you log in at priviledge mode. If there is a valid brain installed, it will have a cryptic name such as c2500-js-l_120-3.bin. Once you have determined that you have the correct brain for your given router, you need to see if somebody turned on the learning settings for this device. The learning settings will govern how much knowledge the device can attain. There are three levels generally. They are as follows: Rock Stupid (also called rommon mode, less than helpful mode, 0x2100 mode) - at this level, the router will never really amount to much in life. This is what your mom warned you about when she brought up the topic of getting a good education! The good news is that you can rapidly advance to a more educated station in life by going to the next educational level. See grade school mode below. Grade School mode (also called Rxboot mode, or the baby IOS mode,boot mode, or 0x2101 mode)- In this mode, you router is in a good position to learn a lot. It will not actually perform any useful work however, because it needs more intelligence to function. It can do the basics, such as find its way around its environment, ask others for directions, and so on. Of course, it will never rise to its full potential until it gets a good education and completes the final education portal (where all future learning takes place). See High Scool diploma mode below. High School diploma mode (also known as Full boot mode, normal boot, 0x2102 mode and other names). This is the full level of educational awareness. This is the mode where all forms of advanced learning take place. It is an absolutely essential prerequisite to have the high school diploma mode before going on to advanced educational pursuits such as BS/BA mode, Masters mode, or PHD mode. We can get to these more advanced modes simply by swapping out our existing brain (IOS) for a better brain (More advanced feature set IOS). Of course, you will have to pay tuition (licensing fees) for that higher education;-) So, to recap, first you need to see if you have a brain installed. Do a "show flash" command at user or priviledged mode to see that a valid operating system exists. Check what you have against the chart on this page to see if it is correct: http://www.cisco.com/warp/public/620/4.html or, http://www.cisco.com/warp/public/620/1.html or, http://www.cisco.com/warp/public/620/5.shtml#identifiers Once you know you have the correct brain for your router, then see if it is set to the proper leaning mode listed above. This is done very simply by inspecting the learning index indicator (also called the configuration register) with the following command: "show version" Look for the output at the bottom (after pressing the space bar once) for the configuration register setting. If it is anything other than high school mode (0x2102), you may need to change it. Go into your device and get to the following prompt: Router(boot)# configure terminal Router(boot)(config)#configuration-register 0x2102 Finally

That will be a matter
