Syntax Helper; Command Shortcuts - Extreme Networks ExtremeWare XOS Guide Manual

Accessing the Switch

Syntax Helper

The CLI has a built-in syntax helper. If you are unsure of the complete syntax for a particular command,
enter as much of the command as possible and press [Tab] or [?]. The syntax helper provides a list of
options for the remainder of the command and places the cursor at the end of the command you have
entered so far, ready for the next option.
If you enter an invalid command, the syntax helper notifies you of your error and indicates where the
error is located.
If the command is one where the next option is a named component (such as a VLAN, access profile, or
route map), the syntax helper will also list any currently configured names that might be used as the
next option. In situations where this list is very long, the syntax helper lists only one line of names,
followed by an ellipses (...) to indicate that there are more names that can be displayed.
The syntax helper also provides assistance if you have entered an incorrect command.
Abbreviated Syntax
Abbreviated syntax is the shortest unambiguous allowable abbreviation of a command or parameter.
Typically, this is the first three letters of the command. If you do not enter enough letters to allow the
switch to determine which command you mean, the syntax helper will provide a list of the options
based on the portion of the command you have entered.
NOTE
When using abbreviated syntax, you must enter enough characters to make the command unambiguous and
distinguishable to the switch.

Command Shortcuts

Components are typically named using the command. When you enter a command to configure
create
a named component, you do not need to use the keyword of the component. For example, to create a
VLAN, enter a VLAN name:
create vlan engineering
After you have created the name for the VLAN, you can then eliminate the keyword from all other
vlan
commands that require the name to be entered. For example, instead of entering the modular switch
command:
configure vlan engineering delete port 1:3,4:6
you could enter the following shortcut:
configure engineering delete port 1:3,4:6
Although it is helpful to have unique names for system components, this is not a requirement. If
ExtremeWare XOS encounters any ambiguity in the components within your command, it generates a
message requesting that you clarify the object you specified.
