Abbreviating Commands
You can abbreviate most commands down to the fewest unique characters for a command; for example,
you can enter
wr t to view the configuration instead of entering the full command write terminal, or
you can enter
en to start privileged mode and con te to start configuration mode. In addition, you can
enter
0 to represent 0.0.0.0.
