Operating modes and functions
This section is an introduction to the functions and operating modes of your device. It
includes information on the following points:
Security for your configuration
Security for your LAN
IP routing
Bridging
DHCP server
Along with the description of the individual points, we will also give you information to
support you as you configure your device.
Detailed sample configurations can be found in the Workshop.
Please refer to the electronic documentation for a detailed description of all parameters
and menus.
Security for your configuration
A number of important parameters for the exchange of data are established in the
configuration of the device. These include the security of your network, monitoring of
costs and the authorizations for the individual network users.
Needless to say, the parameters that you have set should not be modified by
unauthorized persons. The
ELSA MicroLink Cable
thus offers a variety of options to
protect die configuration.
Password protection
The simplest option for the protection of the configuration is the establishment of a
password. As long as a password hasn't been set, anyone can change the configuration
of the device.
The password input field can be found in the configuration tool
ELSA LANconfig
in the
'Management' configuration section on the 'Security' tab. The password prompt can be
activated in a terminal or telnet session in the
/Setup/Config-Module/
passw.prompt
menu. In this case, the password itself is set with the command
passwd
.

ELSA MicroLink Cable
is protected against “brute force attacks“
by barring logins. A brute-force attack is the attempt of an unauthorized person to crack
