28.4 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 “
configuration” automatically displays. 
 Each interface refers to a switch Ethernet port. 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.
