Accessing the Switch
3
The value part of the command specifies how you want the parameter to be set. Values include
numerics, strings, or addresses, depending on the parameter.
4 After entering the complete command, press [Return].
NOTE
If an asterisk (*) appears in front of the command-line prompt, it indicates that you have outstanding
configuration changes that have not been saved. For more information on saving configuration changes,
see Appendix B.
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]. 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 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 might be very long, the syntax helper will list only one line of
names, followed by an ellipses to indicate that there are more names than 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
All named components of the switch configuration must have a unique name. Components are typically
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
command:
configure vlan engineering delete port 1-3,6
you could enter the following shortcut:
configure engineering delete port 1-3,6
