This section describes how to enter CLI commands.

RGUMENTS
A CLI command is a series of keywords and arguments. Keywords identify
a command, and arguments specify configuration parameters. For
example, in the command “show interfaces status ethernet 1/5,”
show
interfaces and status are keywords, ethernet is an argument that
specifies the interface type, and 1/5 specifies the unit/port.
You can enter commands as follows:
◆
To enter a simple command, enter the command keyword.
◆
To enter multiple commands, enter each command in the required
order. For example, to enable Privileged Exec command mode, and
display the startup configuration, enter:
Console> enable
Console# show startup-config
◆
To enter commands that require parameters, enter the required
parameters after the command keyword. For example, to set a
password for the administrator, enter:
Console(config)# username admin password 0 smith

a command. For example, the command “configure” can be entered as

OMPLETION
If you terminate input with a Tab key, the CLI will print the remaining
characters of a partial keyword up to the point of ambiguity. In the “logging
history” example, typing
log followed by a tab will result in printing the
command up to “ logging .”
