Since you are learning Cisco CLI, I strongly recommend using "exit" and "end" and do not use any shortcuts until u become CLI master.
this is just in case exam asks u question about config mode, like what config mode "ip address x.x.x" belongs to?
exam sim software may not support shortcuts like wr, en, do, config t, and so on
tab and ? and other commands maybe disabled for purpose of testing knowledge,
use exit to step out of current config mode;
use end when u done configuring device,
Hello Martin, If I got you well it means everytime I configure and interface I would have to exit before Configuring another one ? Is that correct? and also another question let's assume I'm in an interface mode and after that I want to be in a global mode to configure an Ip route l, should I Exit the interface mode or end it before configuring an IP route? Thank you
No, u do not have to exit as pointed out by Steven. For purpose of learning and passing CCENT exam, you should know different config modes and where u need to be to configure things.
If u in wrong place, CLI will let u know by not accepting command. CLI may accept command that does not belong there but it will kick you out and place u in correct mode. it's automatically place you in correct spot but you just do not see that.
for example, u added ip address under interface, then u add ip route x.x.x.x xx.x.x.x, you are now in global config mode. u were moved out of interface mode and ended up in global config mode. CLI did "exit" for you. Just be aware of this CLI behavior.
it seems that you already know various config modes and where to configure things. Do not worry too much about it. you will learn this by configuring things. Kudos!
Note: Ctrl + Z is the key shortcut for 'End' command.
