Password / SNMPv3 access

This dialog gives you the option of changing the read and read/write passwords for access to the device via the graphical user interface, via the CLI, and via SNMPv3 (SNMP version 3).
Set different passwords for the read password and the read/write password so that a user that only has read access (user name “user”) does not know, or cannot guess, the password for read/write access (user name “admin”).
If you set identical passwords, when you attempt to write this data the device reports a general error.

The graphical user interface and the command line interface (CLI) use the same passwords as SNMPv3 for the users “admin” and “user”.

Note: Passwords are case-sensitive.
Note: As the graphical user interface displays the communities readably in the dialog for SNMPv1/v2, this dialog can only be accessed by a user who has logged in with the user name “admin” and the correct read/write password.
Note: When you change the SNMPv3 password for the user name with which you have logged in to the graphical user interface, log in again so that you can access the graphical user interface of the device again. Otherwise you will get a general error message when you attempt to access it.
Note: If you do not know a password with “read/write” access, you will not have write access to the device.
Note: For security reasons, the device does not display the passwords. Make a note of every change. You cannot access the device without a valid password.
Note: For security reasons, SNMPv3 encrypts the password. With the “SNMPv1” or “SNMPv2” setting in the dialog Security:SNMPv1/v2 access, the device transfers the password unencrypted, so that this can also be read.
Note: Use between 5 and 32 characters for the password in SNMPv3, since many applications do not accept shorter passwords.

You can block access via a Web browser, SSH or Telnet client in a separate dialog.

Access at IP address level is restricted in a separate dialog.
