Snmp Global Settings; Snmp Traps Settings - D-Link xStack DGS-3420 Series Reference Manual

xStack® DGS-3420 Series Layer 2 Managed Stackable Gigabit Switch Web UI Reference Guide
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
The Switch in the Management Information Base (MIB) stores management and counter information. 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. Specifying the MIB
Object Identifier may also retrieve the proprietary MIB. MIB values can be either read-only or read-write.
The Switch 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 Switch 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.
