How to enter a command
Basics
You can enter a command by logging in to a CLI via the EM serial console or telnet/SSH.
How to enter a command
Enter a command defined in this document after a prompt is displayed.
When a command is correctly entered, the CLI executes a process according to the command.
Only one command can be specified in a line at the same time. Multiple commands cannot be specified at
the same time.
Depending on a command, you can specify multiple arguments. You have to insert at least one blank space
between a command and an argument.
Command syntax
<command> <the first argument> <the second argument> … <the Nth argument>
Command:
Specify behavior for the argument(s) to follow
Argument:
Specify an object for the behavior mentioned above.
Multiple arguments can be specified. You can specify static parameter, variable parameter (e.g.
address, time), and URL, for argument.
A CLI checks a specified command from the top of lines. When conditions to execute a command/an
argument are satisfied, a CLI processes a command.
Numeric value specification
Specify in decimal (0-9).
Character string specification
Specify with alphanumeric characters and some symbols (to be specific, a-zA-Z, 0-9, space, '-' (dash),
'_' (underscore)) in any combination.
The first character must be always an alphabet (a-zA-Z). You can specify alphanumeric characters for
the following characters.
For specifying a URL, you can use '@' (at sign), ':' (colon), '/' (slash mark), and '.' (dot).
When you specify a character string that contains any space, enclose the character string with double
quotations.
IP address specification
Some commands require IP address to be specified.
Specify an IP address as follows.
Format: ###.###.###.###
###: Specify in one through three digits in decimal.
