Agent SNMP Configuration

How SNMP works
Using SNMP (Simple Network Management Protocol), a network management station can
configure and monitor SNMP-compliant nodes, such as a SCALANCE X-200RNA. To allow
this, a management agent is installed on the SCALANCE X-200RNA with which the
management station exchanges data. There are three frame types:
● Read (management station fetches values from a SCALANCE X-200RNA)
● Write (management station writes values to a SCALANCE X-200RNA)
● Send events to registered nodes (traps). The agent sends messages to registered
management stations.
Access permissions with SNMP
When using the SNMP protocol, you specify access permissions by means of the community
string. A community string contains information about the user name and password in a string.
Different community strings are defined for read and write permissions. More complex and
more secure authentications are possible only in some SNMPv2 variants and in SNMPv3.
Note
To preserve security, you should not use the default values "public" or "private".
Configuration of SNMP with a SCALANCE X-200RNA
The "Agent SNMP Configuration" dialog box appears if you click the "SNMP" folder icon.
In the "Agent SNMP Configuration" dialog box, you make the basic settings for SNMP. Enable
the check boxes according to the SNMP functionality you want to use. For detailed settings
(for example traps), there are separate menu items in WBM.
