Figure 4.4.5.33-1 SNMP Attribute
The screen shows that SNMP Attributes are divided into three categories: SNMP Agent, SNMP Security, and
SNMP Trap. The SNMP Service field enables the SNMP agent to run in the iPECS call server. The SNMP port
field defines the UDP port used for communications from the iPECS system for SNMP messages. This port
should not be changed.
In SNMP Security are the Read Only and Read Write SNMP Community fields, 4 to 16 characters. The SNMP
community designates an SNMP communication group to which an SNMP message belongs and is a logical
relationship between the SNMP agent (iPECS system) and SNMP manager (iPECS NMS). The SNMP
community settings must be the same for the iPECS system and the iPECS NMS server.
Read Only Community (default=Public)—Defines a community string used when theiPECS NMS
reads data from the iPECS system.
Read Write Community (default=Private)—Defines the community string used wheniPECS NMS reads
or writes data to iPECS system.
Although the iPECS system can accept packets from any SNMP manager such as iPECS NMS, for improved
security, the IP address of specific servers can be defined and allowed Read-only or Read-Write access. It is
recommended that the system be assigned the IP address of a specific NMS server with reading Write
access.
The SNMP Trap configuration defines the Trap Community and the Trap Destination, which includes the IP
Address of the SNMP manager, iPECS NMS, and the .message type. The Trap Community designates a
communication group to which a Trap message belongs and is a logical relationship between the SNMP agent
(iPECS system) and SNMP manager (iPECS NMS).
