12.2.3 SNMP
Simple Network Management Protocol (SNMP) is used in network management systems to
configure and monitor network-attached devices. SNMP is an IETF standard defined by
RFC 1157, 1441 and additional RFCs for specific Management Information Base (MIBs).
MP-20x contains an embedded SNMP agent and supports SNMPv1, SNMPv2 and partially
supports SNMPv3. For monitoring of the network interfaces, the standard SNMP MIB-II
(RFC 1213) is supported. For more options, a proprietary MIB, AC-MP20X-MIB includes
the following sections:
„ acMP20xConfig: for changing MP-20x's configuration
„ acMP20xStatus: for monitoring MP-20x's status
„ acMP20xAlarms: for receiving notifications (alarms) from MP-20x
The figure below shows the SNMP network architecture:

12.2.3.1 Configuring MP-20x via SNMP
The acMP20xConfig MIB section is structured in a similar hierarchy as MP-20x's Web GUI.
Each parameter in the MIB has a matching parameter in the Web GUI and a matching
parameter in the gateway’s configuration file. The MIB file defines the valid range and the
default value for each parameter. Typically, the customer integrates the MP20x MIB into
the customer's Network Management System (NMS) to automate the configuration
process.
Note:
A special MIB object is defined to allow MP-20x firmware upgrade triggered by
SNMP. The object acMP20xRemoteUpdate triggers a remote upgrade from
the SNMP-configured URL.
