SETTING ROUTER BANNER

Router(config)# set banner motd #Welcome to CCNA#
Router(config)# set banner login #Welcome to CCNA#

COPY COMMAND

Copy current active configuration (Running Configuration) from RAM to NVRAM (Startup Configuration). If power outage occur and Router will reboot, then router will check it's NVRAM for configuration file

Router# copy running-config startup-config

RESSETING TO FACTORY DEFAULT

To reset the switch to factory default, issue the erase startup-config or write erase command. This command does not clear the boot variables, such as config-register and boot system settings. You can alter the boot system parameters with the boot command

Router# erase startup-config

or

Router# write erase

Now that we have deleted our configuration lets reload the router. The router notices that you have a configuration and ask you if you would like to save it before you reload. We don't want to save it so we are going to select 'NO'

Router#reload
