8.4 SNMP
SNMP (Simple Network Management Protocol) is the most widely-used network management
protocol on TCP/IP-based networks. SNMP provides an easy mechanism for managing a
network using a simple Command-Response protocol defined between the Manager and the
managed entities. The management is performed through MIBs (Management Information Base)
supported by the managed entities. The MIBs contain configuration elements which can be either
Viewed (GET) or Modified (SET) by the Managers.
SNMPv3 is designed mainly to overcome the security shortcomings of SNMPv1/v2. USM (User
based Security Model) is the main feature added as part of the SNMPv3 specification. USM
provides for both encryption and authentication of the SNMP PDUs. With SNMPv3, the SNMP
communication is completely safe and secure.
The configuration of the switch can be accessed and changed directly using SNMP commands.
This section allows you to specify the basic SNMP settings. This switch software supports SNMP
versions 1/2c and 3. You may also enable both versions simultaneously.

Change Password tab
The switch software is password-protected to prevent unauthorized access. The admin password
should consist of at least six characters. The password must always be entered to gain access
to the software.
There are two access levels, which can be chosen from the drop-down list:
Function
Description
Admin
All rights are available.
Guest
All settings and values can only be viewed. It is not possible to alter
the password or other settings.
The system administrator is authorized to alter the valid password for the access levels for the
administrator and guest in this section. The admin password must be specified correctly before
you can change a password. Click
Apply
to confirm your entry. The new password will become
valid when the switch is rebooted.
If the administrator password is forgotten or if it becomes necessary to alter it due to technical
reasons, this process can be carried out using the Multifunction Button. To learn how to use the
Multifunction Button refer to Chapter 5 –
