Cisco 1921 Router, Initial config (running-config cleared) after reload

Erik Hennerfors

Hi

I've configured my Cisco 1921 Router and saved the running-config to startup-config but when I cut the power or reboot(reload) the router I get the following:

"Would you like to enter the initial configuration dialog? [yes/no]:"

And the running config is cleared, why? I write "wr" after every change and copy the config to startup-config.¨

Regards

Erik

Hi Eirk,

Check the "show version" command and verify what is the configuration register set to. To boot with saved running configuration it should as below.

Configuration register is 0x2102

Hi,

Now the config sticks after a reload but the router spamms:

%Error opening tftp://255.255.255.255/router.cfg (Timed out)

%Error opening tftp://255.255.255.255/network-confg (Timed out)

%Error opening tftp://255.255.255.255/cisconet.fg (Timed out)

%Error opening tftp://255.255.255.255/router-confg (Timed out)

How come?

Never mind, found out why
