Online Help

When configuring the switch, you can use the online help to get related help information. The CLI
provides two types of online help: complete and partial.
Complete online help

view and their brief descriptions. The following takes user view as an example.

User view commands:

cd
clock
cluster
copy
debugging
delete
dir
display
<Other information is omitted>
2) Enter a command, a space, and a question mark (?).
If the question mark "?" is at a keyword position in the command, all available keywords at the position
and their descriptions will be displayed on your terminal.
<Sysname> clock ?
datetime
summer-time
timezone
If the question mark "?" is at an argument position in the command, the description of the argument will
be displayed on your terminal.
[Sysname] interface vlan-interface ?

If only <cr> is displayed after you enter "?", it means no parameter is available at the "?" position, and
you can enter and execute the command directly.
