Hot Keys and Shortcuts

• Tab - Completes the remainder of the command or

keyword

• Ctrl-R - Redisplays a line

• Ctrl-Z - Exits configuration mode and returns to the EXEC

• Down Arrow - Allows user to scroll forward through former

• Ctrl-Shift-6 - Allows the user to interrupt an IOS process

such as ping or traceroute

• Ctrl-C - Aborts the current command and exits the

configuration mode

IOS Configuration mode

• Interface mode - to configure one of the network

interfaces (Fa0/0, S0/0/0, )

• Line mode - to configure one of the lines (physical or

virtual) (console, AUX, VTY, )

• Router mode - to configure the parameters for one of the

routing protocols
