3.10.3 Simple Network Management Protocol (SNMP)
The Simple Network Management Protocol (SNMP) serves to monitor and control network elements by a
central station. It permits the reading and writing of system variables.
Community
SNMP queries are sent by the management station with a so-called community string that represents a
simple access restriction. Community strings can be created or deleted in the SNMP menu (Figure ). The
overview table displays the currently defined community strings and access permissions. The following
entries are required for creating a community string:

Community string : Define a community string here. By default, the string public is used for
read/write access and the string private for read-only access.

Mode : Select whether the user can only read data from the device (read-only) or can also edit data
(read/write).

Trap setting
If an alarm is triggered, the PROmesh P20 can sent alarms to one or several management stations via
SNMP. You can save the receiver addresses in this menu. Additionally, the community that you have
created in the Community menu has to be entered.
