Understanding the Command Syntax 35
Abbreviated Syntax Abbreviated syntax is the shortest, most unambiguous, allowable
abbreviation of a command or parameter. Typically, this is the first three
letters of the command.
When using abbreviated syntax, you must enter enough characters to
make the command unambiguous, and distinguishable to the switch.
Command Shortcuts
All named components of the switch configuration must have a unique
name. Components are named using the
create
command. When you
enter a command to configure a named component, you do not need to
use the keyword of the component. For example, to create a VLAN, you
must enter a unique VLAN name:
create vlan engineering
Once you have created the VLAN with a unique name, you can then
eliminate the keyword
vlan
from all other commands that require the
name to be entered. For example, instead of entering the Switch 9100
command
config vlan engineering delete port 1-3,6
you could enter the following shortcut:
config engineering delete port 1-3,6
Switch 9100
Numerical Ranges
Commands that require you to enter one or more port numbers on a
Switch 9100 use the parameter
<portlist>
in the syntax. A portlist can
be a range of numbers, for example:
ports 1-3
You can add additional port numbers to the list, separated by a comma:
ports 1-3,6,8
Names All named components of the switch configuration must have a unique
name. Names must begin with an alphabetical character and are
delimited by whitespace, unless enclosed in quotation marks.
