Accessing the CLI online help
The CLI online help is context sensitive. You can enter a question mark at any prompt or in any position
of a command to display all available options.
To access the CLI online help, use one of the following methods:
• Enter a question mark at a view prompt to display the first keyword of every command available in
the view. For example:
?
User view commands:
archive Specify archive settings
backup Backup next startup-configuration file to TFTP server
boot-loader Set boot loader
bootrom Update/read/backup/restore bootrom
cd Change current directory
…
• Enter a space and a question mark after a command keyword to display all available, subsequent
keywords and arguments.
{
If you type a question mark in place of a keyword, the CLI displays all possible keyword
matches with a brief description for each keyword. For example:
terminal ?
debugging Send debug information to terminal
logging Send log information to terminal
monitor Send information output to current terminal
trapping Send trap information to terminal
{
If you type a question mark in place of an argument, the CLI displays the description of this
argument. For example:
system-view
[Sysname] interface vlan-interface ?
<1-4094> VLAN interface number
[Sysname] interface vlan-interface 1 ?
[Sysname] interface vlan-interface 1
The string 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 the string. For example:
f?
fdisk
fixdisk
format
free
ftp
display ftp?
ftp
ftp-server
ftp-user
