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. Command Syntax Symbols summarizes command syntax symbols you may see throughout this guide.

Note

ExtremeXOS software does not support the ampersand (&), left angle bracket (<), or right angle bracket (>), because they are reserved characters with special meaning in XML.

Table 1. Command Syntax Symbols
Symbol	Description
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 port [port_list \| all] you must specify either specific ports or all for all ports 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 configure snmp add community [readonly \| readwrite] alphanumeric_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 {time month day year hour min sec } {cancel} {msm slot_id} {slot slot-number \| node-address node-address \| stack-topology {as-standby} } You can specify either a particular date and time combination, or the keyword cancel to cancel a previously scheduled reboot. (In this command, 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.
