27.4 Command Syntax Conventions
The rules of the commands are listed next.
• The command keywords are in
courier new font.
• The required fields in a command are enclosed in angle brackets <>, for instance,
ping
<ip>
means that you must specify an IP number for this command.
• The optional fields in a command are enclosed in square brackets [], for instance,
configure snmp-server [contact <system contact>] [location
<system location>]
means that the contact and location fields are optional.
• “Command” refers to a command used in the command line interface (CI command).
•The | symbol means “or”.
•The entry
<cr> in the command lines refers to carriage return. Press [ENTER] or carriage
return after a command to execute the command.
• Use the up (y) or down (z) arrow key to scroll through the command history list.
• The CLI does not accept partial or incomplete commands. You may enter a unique part of
a command and press
[TAB] to have the switch automatically display the full command.
For example, if you enter “
config” and press [TAB], the full command of “configure”
automatically displays.
• Each interface refers to an Ethernet port on the switch. Commands configured after the
interface command correspond to those ports.
• Type multiple ports or port ranges separated by a comma. Ranges of port numbers are
typed separated by a dash.
