PATH:
    Qualifier for a menu or parameter separated by / or \
    .. stands for upper level
    .  stands for current level

VALUE:
    Possible input.
    Use "" to indicate an empty value.
    Use "*" to add/edit a table row with an actual asterisk.

NAME:
    sequence of _ 0..9 A..Z
    first character must not be numeric case does not matter

FILTER:
    Command output filter
    The output generated by some commands can be limited by specifying a filter
    expression. The filtering is not done line by line, but block by block
    depending on the command executed.
    A filter expression begins with a stand-alone '@' character and ends either
    at the end of the line or with a stand-alone ';' character which terminates
    the current command. A filter expression is furthermore composed of one or
    more search patterns separated by space characters. The search patterns can
    be preceded by no operator ('or' pattern), by a '+' operator ('and' pattern)
    or by a '-' operator ('not' pattern). When the command is executed, a block
    of information is outputted if at least one of the 'or' patterns, all of the
    'and' patterns and none of the 'not' patterns match. The search is not case
    sensitive. If a search pattern is to contain characters which otherwise have
    a special meaning in this filter syntax (e. g. the space character), it can
    be quoted as a whole within '"' characters. Alternatively the special
    characters can be escaped by a '\' character. If the '"' and the '\'
    characters are to be searched for themselves they must be escaped with the
    '\' character.

Remark:
    Unique prefix is sufficient to type a command or path.

4. Listing a table entry:

This example shows how to display a single table entry directly as a list. 

The connection parameters of the VPN peer LANCOM-TEST are to be displayed.

root@LANCOM-1780EW-3G:

> cd /Setup/VPN/VPN-Peers/LANCOM-TEST (this command changes the path directly to the VPN peer LANCOM-TEST)

root@LANCOM-1780EW-3G:/Setup/VPN/VPN-Peers/LANCOM-TEST

> ls (this command shows all parameters of this table entry as a list)

Peer                           INFO     : LANCOM-TEST
SH-Time VALUE                     : 9999
Extranet-Address VALUE     : 0.0.0.0
Remote-Gw VALUE               : 8.8.8.8
Rtg-tag VALUE                       : 0
Layer VALUE                          : P-LANCOM-TEST
dynamic VALUE                    : No
IKE-Exchange VALUE           : Main-Mode
Rule-creation VALUE            : manually
DPD-Inact-Timeout VALUE  : 60
IKE-CFG VALUE                      : Off
XAUTH VALUE                        : Off
SSL-Encaps. VALUE               : No

9. Auto-Complete with the tabulator key:

By means of auto-complete via the tabulator key console commands can be entered much quicker.

Pressing the tabulator key twice [Tab][Tab] shows all possible console paths.

root@LANCOM-1781AW:/

> cd /s  [Tab][Tab]

/Status/ /Setup/ (all menus are displayed which begin with S)

Enter  cd /Se [Tab]

root@:/

> cd /Setup/V [Tab][Tab]

Enter V eingeben [Tab][Tab]

VPN/ VLAN/ (all menus are displayed which begin with V)

Enter  P eingeben [Tab] [Enter key]

root@LANCOM-1781AW:/

> cd /Setup/VPN/ (the console path is changed to Setup → VPN)

When using the command passwd without additional parameters first the old password has to be entered and afterwards the new password has to be entered twice. 

With the command passwd -n   [new password] [old password] the device password can be changed without the additional prompt.

root@LANCOM-1781AW:/

> passwd -n lancomnew lancom (the device password is to be changed from "lancom" to "lancomnew")

Password has been changed

By using the arrow keys "up" and "down" it is possible to invoke console commands anew which have already been used within a console session. This is especially useful when changing the console path.
