Trouble trying to reset a 2501 Router

veritas_libertas

Well I am now into the router programming section of the CCENT. I turned on one of the 2501s that I bought on eBay and was greeted to a locked down router that appears to be looking for a configuration file that it cannot find. I have tried this link on Cisco's web site and it is not helping me. Frustrating since I usually don't have trouble figuring out how to program other devices. Here is what I get when I first power it on. Any suggestions are readily welcomed.

If you're asking about disabling the autoinstall, then no service config in global config mode should do it.

Well, I am just trying to figure out reset the switch so I can get access to programming the router. I can't use the enable command because I don't know the password.

Then it sounds like you need the link to The Sun Source of ALL Cisco Password Recovery Links

Password Recovery Procedures - Cisco Systems

Well, I just figured it out. I was getting frustrated because I kept pressing tab to try and bypass the default configuration. I still don't know what the correct key would have been for Putty, but it doesn't matter. I used Hyperterminal with CTRL+Break.

Another question: I turned off my 2501 and came back to it today only to find that my configuration settings had defaulted to back to like new settings with the cheerful "would you like to..."

I figured I must have not written the image in so I ran through the whole thing again and made sure I typed in 'write' at the end. Much to my dismay this didn't work after I typed in 'reload'. I am hoping I am only making a mistake.

For password recovery you change the configuration register to bypass the startup configuration (0x2142) -- so when you're done you need to put it back.....

Is that enough of a hint?

I understand what you are saying, I am just not sure how to do that.

[Edit] I figured it out :embarrassed:

Router# config t
Router(config)#config-register 0x2142

Hope this help.

Actually no, the config-register 0x2142 will ignore the startup-config as mikej412 pointed out, when you are done with the password recovery, you need the default which is 0x2102.

Another good link to know more about the config-register:

Thanks, I was looking for write up on this whole config-register thing.

Hi,

I got it wrong, i though he want this one (0x2142) not 0x2102.

Looks like you figured this out anyway... But in PuTTY to do a BREAK you click on the upper-left icon and select Special Command > Break. I don't think there's a key sequence for it though.

I uploaded a pic, hopefully that explains it.

Thanks! I actually prefer PuTTY and was wondering how to do that.
