Understanding the Command Syntax 4-3
config vlan engineering add port 1-3,6
could use the following shortcut:
config engineering add port 1-3, 6
Numerical Ranges Commands that require you to enter one or more port numbers use
the parameter,
<portlist>,
in the syntax. A portlist can be a range of
numbers, for example:
port 1-3
You can add additional port numbers to the list, separated by a
comma:
port 1-3,6,8
Names All named components of the Switch configuration must have a unique
name. Names must begin with an alphabetical character delimited by
white space, unless enclosed in quotation marks.
Symbols You may see a variety of symbols shown as part of the command
syntax. These symbols explain how to enter the command, and you do
not type them as part of the command itself. Table 4-1 summarizes
command syntax symbols.
Table 4-1 Command Syntax Symbols
Symbol Description
angled brackets < > Enclose a variable or value. You must specify the variable or value. For example, in
the syntax
config vlan <name> ipaddress <ip_address>
you must supply a VLAN name for <name> and an address for <ip_address> when
entering the command. Do not type the angle brackets.
square brackets [ ] Enclose a required value or list of required arguments. One or more values or
arguments can be specified. For example, in the syntax
disable vlan [<name> | all]
you must specify either the VLAN name for <name>, or the keyword “all” when
entering the command. Do not type the square brackets.
