1.6.4 Entering a ? in a Command
Typing a ? (question mark) usually displays help information. However, some commands allow you to
input a ?, for example as part of a string. Press [CTRL+V] on your keyboard to enter a ? without the Zyxel
Device treating it as a help query.
1.6.5 Command History
The Zyxel Device keeps a list of commands you have entered for the current CLI session. You can use
any commands in the history again by pressing the up () or down () arrow key to scroll through the
previously used commands and press
[ENTER].
1.6.6 Navigation
Press [CTRL]+A to move the cursor to the beginning of the line. Press [CTRL]+E to move the cursor to the
end of the line.
1.6.7 Erase Current Command
Press [CTRL]+U to erase whatever you have currently typed at the prompt (before pressing [ENTER]).
1.6.8 The no Commands
When entering the no commands described in this document, you may not need to type the whole
command. For example, with the “[no] mss <536..1452>” command, you use “mss 536” to specify
the MSS value. But to disable the MSS setting, you only need to type “no mss” instead of “no mss 536”.
1.7 Input Values
You can use the ? or [TAB] to get more information about the next input value that is required for a
command. In some cases, the next input value is a string whose length and allowable characters may
