SNMP
SNMP Settings
Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed specifically for managing
and monitoring network devices. SNMP enables network management stations to read and modify the settings of gateways,
routers, switches, and other network devices. Use SNMP to configure system features for proper operation, monitor
performance and detect potential problems in the Switch, switch group or network.
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.
The DGS-3312SR supports the SNMP versions 1, 2c, and 3. You can specify which version of the SNMP you want 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 SNMP v.1 and v.2, user authentication is accomplished using 'community strings', which function like passwords. The
remote user SNMP application and the Switch 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 SNMP v.1 and v.2 management access are:
public - Allows authorized management stations to retrieve MIB objects.
private - Allows authorized management stations to retrieve and modify MIB objects.
