Question

is it neccessary to erase startup-config when configuring an cisco 1841 router (out of box)

Asked by: jomfra

Hello expert,

I have a new cisco 1841 router.

I about to configure same for frame-relay .

I was looking at a cbt  cisco learning video and the instructor

was saying you need to issue either of the following commands.

ERASE STARTUP-CONFIG   OR RELOAD to erase the current config and start

with a default configuration .

The router will then prompt you for all the information to relevant to your desire

Setup.

I am confused because this is a out of box router.

Can any expert share there experience and provide the correct way to

Start this configuration.

Regards

Jomo

If it's a brand new router (never used) then it will not have any configuration. When you power it up with no config, it will run the "setup dialog" which will prompt you for SOME configuration info. It will not prompt you for frame-relay information.

If when you power it up, it does not ask if you want to run the setup dialog, then there is an existing configuration. You must then issue an "erase start" and then "reload" (without saving the config) to reset the router to an unconfigured state.

The 1841's i get from cisco (still has cisco tape sealed over the box) has a simple config on it and does not ask if you want to run the setup wizard.
It just has no passwords and allows you to login and enable. It also has SDM enabled and fa0/0 has the address of 10.10.10.1 and DHCP server enabled for that range and an access list of that local network for the vty and SDM. I just console in, remove or change the config i don't want and put on the config i want, write mem, and all is good

That's a new one to me. It sounds like Cisco is trying to make the router more "user friendly" for SDM purposes.

So if you want it wiped clean just get in and do a "erase start" followed by a "reload".
