Entering Commands in the CLI
The GigaVUE CLI provides several conventions that make it easy to identify
available commands and enter them quickly:
Command-Line Syntax – Entering Commands
You enter configuration commands for the GigaVUE node in the
command-line interface by typing enough characters to uniquely identify the
command and pressing
<Enter> .
Technique Description
Context-Sensitive Help
The ? symbol is the key to receiving help wherever you are in
the CLI:
• Type the
?
by itself to see a list of all available commands.
• Word Help – Type a partial word with a ? mark immediately
following the partially-typed word to see a list of all possible
commands using the word entered so far.
For example, if you typed i? in Configure mode, the CLI
would return the following possible commands based on
what you’ve entered so far:
image interface ip
• Command Help – Type a command followed by a question
mark to see all possible arguments for the command as
entered. If the system returns
<cr> , that means the
command can be entered as-is.
For example, if you entered gigastream ? , you would see
alias . You can build your way through the entire command
tree by entering ? after each new argument. For example,
after entering gigastream alias myalias ? , you would see
the next valid argument – port-list .

OTE
:
Typing ? accesses the help system immediately – you do
not need to press <Enter> .
Partial Command
Entry
For all GigaVUE commands and arguments, you only need to
enter enough characters to distinguish the command from all
other available commands. So, for example, you do not have to
enter the full command
username – there is only one
command starting with the letter u , so you only have to enter u .
Command Completion
If you have partially typed a command, you can press Tab and
the CLI will attempt to complete the command for you based on
what’s been entered so far.
It is helpful to use the Command Completion feature together
with partial command entry – you can press Tab while entering
a command to see a list of all available commands matching
what you’ve entered so far. For example, you can press
p<Tab>
and the system will return:
pass-all ping port port-pair
Based on this information, you know that you only need to enter
the letter
pa to uniquely identify what you’ve entered as
pass-all.
