User EXEC
Users first logging in to the CMTS are assigned non-privileged status. The command line prompt will be the machine name
followed by a greater-than sign (>). There are two levels of User EXEC, signified by a 0 (zero) or 1 (one). The 0 commands
are associated with logging in, changing privilege levels, and logging out as shown in the following list:
disable exit [all]
enable no logout
enable [<int>] quit [all]
end
The level 1 commands are only a subset of the CLI commands, the ones that display non-privileged information. You are
not able to enter commands to change configuration or display privileged information until you become a privileged user.
Privileged EXEC
To become a privileged user, enter the enable command. Normally, you must enter a password to enter Privileged EXEC
mode. You are permitted three unsuccessful attempts to enter a password before the connection attempt is refused. If the
password is accepted, the end of the prompt changes to a pound sign (#).
From Privileged EXEC mode, you may access global configuration mode. In this mode, you can enter commands that
configure general system characteristics. You can also use global configuration mode to enter specific configuration
modes.
CLI Command Modes
The CMTS supports hundreds of CLI commands. They are grouped into different functional modes. The first set of
commands is available to all users including those with non-privileged access. Most of these commands are used to show
system status. They are available when the CMTS is in User EXEC mode or any other mode.
The other modes are available only to users with privileged access. These commands are more powerful and can be used
to reconfigure the system or to adjust system performance. This command reference manual lists the CLI commands in
straight alphabetical order.
The following table lists some of the command modes and some of the commands needed to change from one mode to
another:
