How to Configure SNMP

SNMP (Simple Network Management Protocol) is protocol for configuring and monitoring network elements. The
protocol controls communication between the monitored devices and the monitoring station (SNMP manage-
ment tool). Information can be read and changed.
SNMP exists in 3 versions, the UTN supports version 1 and 2.
SNMPv1
SNMPv1 is the first and most simple SNMP version. A disadvantage is the insecure access control which is the com-
munity: a community groups monitoring station and monitored devices. This makes their administration easier.
There are two types of communities, read-only and read/write. For both the community name is also the pass-
word used between the monitoring station and the monitored devices. As it is transmitted as clear text, it does
not offer sufficient protection.
SNMPv3
SNMPv3 is the newest SNMP version. It contains enhancements and a new security concept which includes,
amongst other thins, encryption and authentication. Therefore, a SNMP user with name and password must be
created in the monitoring station. This user must then be specified in the UTN server.
Important:
The user accounts are also used to access the utnserver Control Center and thus
are to be defined under SECURITY - Control Center, see 'How to Protect Access to
the utnserver Control Center (User Accounts)'  67.
 SNMPv3 users are created in the monitoring station. (Only for SNMPv3.)
 The SNMPv3 users from the monitoring station are specified on the UTN server  67. (Only for SNMPv3.)
1. Start the utnserver Control Center.
2. Select SECURITY – SNMP.
