Yess,
First I'd go
[router]# copy running-config startup-config
then write the memory by
[router]# write memory
It said, OK, DONE, etc..
I rebooted again, and here we go again. Everything from the begining.
By the way When I say "restarting server" I literally mean it, meanwhile, I'm powering off from its button and make it online again. Is there any simpler way?
Sorry I'm too newbie to this.
