• Enter a question mark at a view prompt to display the first keyword of every command available in

the view. For example:

<Sysname> ?

User view commands:

…

• Enter a space and a question mark after a command keyword to display all available, subsequent

keywords and arguments.

with a brief description. For example:

<Sysname> terminal ?

debugging Enable to display debugging logs on the current terminal

logging Display logs on the current terminal

monitor Enable to display logs on the current terminal

tracing Display traces on the current terminal

{ If the question mark is in the place of an argument, the CLI displays the description of the

argument. For example:

<Sysname> system-view

[Sysname] interface vlan-interface ?

<1-4094> Vlan-interface interface number

[Sysname] interface vlan-interface 1 ?

<cr>

[Sysname] interface vlan-interface 1

<1-4094> is the value range for the argument. <cr> indicates that the command is complete

and you can press Enter to execute the command.

• Enter an incomplete keyword string followed by a question mark to display all keywords starting

with that string. For example:

<Sysname> f?
