2.6 SNMP Interface
Communications between an external Simple Network Management Protocol (SNMP) Manager
and a networked group of multiple Digivance systems is supported by an SNMP interface
capability as shown in Figure 1-6. To support the SNMP interface, a PC-type computer loaded
with both the Digivance Element Management System (EMS) software and the SNMP Proxy
Agent software is required. The EMS and SNMP Proxy Agent software plus the associated
Management Information Base (MIB) provide the various control (Set) and monitoring (Get)
functions required to remotely manage multiple Digivance systems using an SNMP Manager.
A Controller Area Network (CAN) port is provided on each HU. Up to twenty-four HU’s may
be linked together through the CAN interface and controlled by the same EMS computer. All
the networked HU’s and the associated RU’s may be managed by connecting the EMS computer
to one HU. The EMS computer provides an RS-232 port (#1) to support the interface with the
networked HU’s.
The SNMP Manager may be linked with the EMS computer through a Local Area Network
(LAN). The EMS computer provides an Ethernet port to support the interface with the LAN.
The SNMP Proxy Agent supports two versions of the SNMP protocol: SNMPv1 and SNMPv2c.
A facility to Register/Unregister an SNMP Manager for receiving traps is also supported by the
SNMP Proxy Agent. The SNMP Manager is not included with the EMS software and must be
provided separately.
