2. Enter part of a command and a ? separated by a space.
If ? is at the position of a keyword, the CLI displays all possible keywords with a brief description for
each keyword. For example:
<sysname> terminal ?

logging Send log information to terminal
monitor Send information output to current terminal
trapping Send trap information to terminal
If ? is at the position of an argument, the CLI displays a description about this argument. For example:
<sysname> system-view
[sysname] interface vlan-interface ?
<1-4094> VLAN interface
[sysname] interface vlan-interface 1 ?
<cr>
[sysname] interface vlan-interface 1
The string <cr> indicates that the command is a complete command. Execute the command by pressing
Enter.
