Traps; Mibs; Snmp User Table - D-Link DGS-3324SR User Manual

D-Link DGS-3324SR Layer 3 Stackable Gigabit Ethernet Switch

Traps

Traps are messages that alert network personnel of events that occur on the Switch. The events can be as serious
as a reboot (someone accidentally turned OFF the Switch), or less serious like a port status change. The Switch
generates traps and sends them to the trap recipient (or network manager). Typical traps include trap messages
for Authentication Failure, Topology Change and Broadcast\Multicast Storm.

MIBs

Management and counter information are stored by the switch in the Management Information Base (MIB). The
Switch uses the standard MIB-II Management Information Base module. Consequently, values for MIB objects
can be retrieved from any SNMP-based network management software. In addition to the standard MIB-II, the
Switch also supports its own proprietary enterprise MIB as an extended Management Information Base. The
proprietary MIB may also be retrieved by specifying the MIB Object Identifier. MIB values can be either read-
only or read-write.
The DGS-3324SR incorporates a flexible SNMP management for the switching environment. SNMP
management can be customized to suit the needs of the networks and the preferences of the network
administrator. Use the SNMP V3 menus to select the SNMP version used for specific tasks.
The DGS-3324SR supports the Simple Network Management Protocol (SNMP) versions 1, 2c, and 3. The
administrator can specify the SNMP version used 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.
SNMP settings are configured using the menus located on the SNMP V3 folder of the web manager.
Workstations on the network that are allowed SNMP privileged access to the switch can be restricted with the
Management Station IP Address menu.

SNMP User Table

The SNMP User Table displays all of the SNMP User's currently configured on the Switch.
In the SNMP Manager folder, click on the SNMP User Table link. This will open the SNMP User Table, as
