1.1.2.2 Configuration Syntax
Switch provides various configuration commands. Although all the commands are
different, they all abide by the syntax for Switch configuration commands. The general
commands format of Switch is shown below:
cmdtxt <variable> {enum1 | … | enumN } [option1 | … | optionN]
Conventions: cmdtxt in bold font indicates a command keyword; <variable> indicates a
variable parameter; {enum1 | … | enumN } indicates a mandatory parameter that should
be selected from the parameter set enum1~enumN; and the square bracket ([ ]) in
[option1 | … | optionN] indicate an optional parameter. There may be combinations of
“< >“, “{ }” and “[ ]” in the command line, such as [<variable>], {enum1 <variable>|
enum2}, [option1 [option2]], etc.
Here are examples for some actual configuration commands:
show version, no parameters required. This is a command with only a keyword and
no parameter, just type in the command to run.
vlan <vlan-id>, parameter values are required after the keyword.
firewall {enable | disable}, user can enter firewall enable or firewall disable for this
command.
snmp-server community {ro | rw} <string>, the followings are possible:
snmp-server community ro <string>
snmp-server community rw <string>
1.1.2.3 Shortcut Key Support
Switch provides several shortcut keys to facilitate user configuration, such as up,
down, left, right and Blank Space. If the terminal does not recognize Up and Down keys,
