10.5.3
Administration port
Access to the web interface of the device can be blocked on certain ports in order
to limit device access.
This can be configured in the web interface under
Configuration > Admin Inter-
faces.
Deactivated ports cannot be configured for administration. This shall
avoid that the user locks out himself.
It is recommended to deactivate all unused ports, because the
management functions cannnot be reached any more under high
network load.
10.5.4
Password change
The password can be changed via the web interface or using an USB flash drive.
10.5.4.1
Web interface
The password can be configured under
Maintaining > Change Password
. The new
password must be entered twice for this due to reasons of security. Then, the pass-
word can be changed using the "change password" button.
10.5.4.2
USB
Alternatively, the password can also be chamged via USB. An USB flash drive is
necessary for this. It has to be prepared as described in the following section.
In order to change the password, an authentication file is required. This file must
have the name "newpassword.pass", the content is the new user name and new
password. The format requirements are described in the next section.
The following conventions apply for the password:
•
at least 5 characters
•
max. 16 characters
•
no special characters, no umlauts
After plugging in the USB flash drive, the password will be changed automatically
without restart. If a web interface session is still active, the session becomes invalid
and the user will be logged out automatically.
