1721 router help!

Unanswered Question

Hi, and thanks in advance for your help!

I bought a 1721 router from pac bell "staged" and bundled with aT1. If i change the en password and do "write mem", "reload", the password goes back to the old one, why?. Does reload mean reload from a stored image? can this router store an image? If i do show config i get "no such command". In fact the show command is tottaly unreconagized. is this normal, or did pac bell load an image and disable some commands? If they loaded an image can i kill it (do i want to kill it)? They did not include a configuration guide like what came with my pix, or i would not be asking such dumb questions! I searched cisco online.. after 2 hours of searching and testing im here writing to you! thanks for the help

Hi Anthony,

After changing the enable password, write mem should update the saved config in NVRAM. You could try 'copy run start' as well in case 'write mem' isn't working for some reason. Reload will reload the router and load the config stored in NVRAM usually, unless the config-register is set to not load the config from NVRAM. At the bottom of the 'show version' output there will be a line that saids what the config-register is. What does that say? If it's something other then 0x2102 change it to 0x2102 and see if it comes up fine.

On reload, does the router perform like it was 'staged' to function or not?

What is the prompt on the router? If it's router-boot or rommon then the config-register may be incorrect.

What version of IOS does the 1721 have?

Regards, Erick

Erick, thanks for the help.

Here is a show version, the show command only works from the en, and not after config t is entered. How can i get rid of the "image" looks like script at the end of the config appears to be what i thought was the image.

Glad to hear you got it fixed. Enable secret will override the regular enable password.
