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 4 summarizes
command syntax symbols.
Limits
The command line can process up to 512 characters, including spaces. If you attempt to enter more than
512 characters, the switch emits an audible “beep” and will not accept any further input. The first 512
characters are processed, however.
Line-Editing Keys
Table 5 describes the line-editing keys available using the CLI.
Table 4: Command syntax symbols
Symbol Description
angle brackets < > Enclose a variable or value. You must specify the variable or value. For example, in the
syntax
configure vlan <vlan> ipaddress <ipaddress>
you must supply a VLAN name for <vlan name> and an address for <ipaddress> 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 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> {msm <slotid>}
| cancel {msm <slotid>}| {msm <slotid>}
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.
