Hi !

Reading Wendel Odom book Official excam certification guide ICND1.

In chapert 8 it's about erasing and copying config files., page 221 states "..To clear out running-config file, simply erase the startup-config file, and then reload the switch".

My question is what happens then ? Does the switch have a IOS to load anymore, if so, where is it stored ?

when it starts again i guess it reads ROM and goes to Setup mode ?

You are confusing the IOS with the running config. The IOS is the operating system for the router. The running config is the current configuration for the router.

If you erase the startup config file and reload the router will still load the IOS ,usually stored in flash on the router or on an external flash card, and then it will go into initial configuration mode ie. it will ask if you want to configure it.

If you say yes it will run you through some basic questions such as interfaces to enable, IP addresses for interfaces, hostname etc.

If you say no it just puts you into line mode. Type "enable" and it will take you into enable mode and you can configure the router from there.
