network devices. The SNMP agent decodes the incoming SNMP messages and responds to requests with MIB
objects stored in the database. The SNMP agent updates the MIB objects to generate statistics and counters.
D-Link provides a professional network management software package, called
D-View 6.0 that uses SNMP to connect,
configure, manage and monitor this switch. The D-View
®
6.0 SNMP Network Management System is a software tool
that facilitates the central administration of a network with various SNMP-enabled devices.

software, go to http://dview.dlink.com.tw/ and download the software and manual.
Managed devices that support SNMP include software (referred to as an agent), which runs locally on the device. A
defined set of variables (managed objects) is maintained by the SNMP agent and used to manage the device. These
objects are defined in a Management Information Base (MIB), which provides a standard presentation of the
information controlled by the on-board SNMP agent. SNMP defines both the format of the MIB specifications and the
protocol used to access this information over the network.
This switch supports
SNMPv1 , SNMPv2c and SNMPv3 . The administrator may specify which version of SNMP to use
to monitor and control the switch. The three versions of SNMP vary in the level of security provided between the
management station and the network device.
In SNMPv1 and SNMPv2c, user authentication is accomplished using 'community strings', which function like
passwords. The remote user SNMP application and the Switch’s SNMP must use the same community string. SNMP
packets from any station that has not been authenticated are ignored (dropped).
The
default community strings
for the Switch used for SNMPv1 and SNMPv2c are:
 public - Allows authorized management stations to retrieve MIB objects.
 private - Allows authorized management stations to retrieve and modify MIB objects
