Getting Context-Sensitive Help
In any command mode, you can get a list of available commands by entering a question
mark (?).
Router> ?
To obtain a list of commands that begin with a particular character sequence, type in those
characters followed immediately by the question mark (?). Do not include a space. This
form of help is called word help, because it completes a word for you.
Router# co?
configure
To list keywords or arguments, enter a question mark in place of a keyword or argument.
Include a space before the question mark. This form of help is called command syntax help
because it reminds you which keywords or arguments are applicable based on the
command, keywords, and arguments you have already entered.
Router# configure ?
memory
network
terminal
<cr>
You can also abbreviate commands and keywords by entering just enough characters to
make the command unique from other commands. For example, you can abbreviate the
show command to sh.
Saving Configuration Changes
Any time you make changes to the router configuration, you must save the changes to
memory because if you do not they will be lost if there is a system reload or power outage.
There are two types of configuration files: the running (current operating) configuration and
the startup configuration. The running configuration is stored in RAM; the startup
configuration is stored in NVRAM.
