36CHAPTER 3: ACCESSING THE SWITCH

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 7 summarizes command syntax symbols.

Table 7 Command Syntax Symbols

Symbol	Description
angle 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
	use image [primary secondary]
	you must specify either the primary or secondary image when entering the
	command. Do not type the square brackets.
vertical bar	Separates mutually exclusive items in a list, one of which must be entered. For
	example, in the syntax
	config snmp community [readonly readwrite] <string>
	you must specify either the read or write community string in the command.
	Do not type the vertical bar.
braces { }	Enclose an optional value or a list of optional arguments. One or more values
	or arguments can be specified. For example, in the syntax
	reboot {<date> <time> cancel}
	you can specify either a particular date and time combination, or the keyword
	cancel to cancel a previously scheduled reboot. If you do not specify an
	argument, the command will prompt, asking if you want to reboot the switch
	now. Do not type the braces.
