SNMP

SNMP is an acronym for Simple Network Management Protocol. This network protocol is used to

manage TCP/IP networks by using “Traps” sent from devices compliant with SNMP and collected by

one or more servers. Devices that comply with SNMP correspond with management applications by

sending alerts and updates, as well as allowing configuration changes.

The DGE-530T’s SNMP agent will take event notices from the adapter, translate and then forward

them to specified SNMP management stations.

Before installing the SNMP agent, you must install SNMP on your computer. Consult the operating

system documentation of your computer for additional information.

To install SNMP on the DGE–530T, simply click Install SNMP Agent on the Introduction page and

complete the steps of the Installation Wizard.

This utility should only be used by experienced network administrators. Additional software or services

may need to be previously installed or configured prior to installation of the SNMP protocol.

D-Link Corporation Network Control

Installed automatically with the driver is the D-Link Network Control program, which may be opened

on the Control Panel of your computer. The configuration and settings information for this program

may be found by clicking the Help button of the current screen. This should provide you with any

information you should need.

The D-Link Network Control Program is supported by Microsoft Windows Server 2003 x86, Microsoft

Windows Server 2003 x64, Microsoft Windows XP x86, Microsoft Windows XP x64, Microsoft Windows

Vista x86, Microsoft Windows Vista x64, Microsoft Windows Server 2008 x86, and Microsoft Windows

Server 2008 x64.

IEEE802.1p Priority Tagging

With the growing number of network applications, local area networks (LANs) must deliver data for a

wide variety of applications. Email, file transfers, database queries, voice over IP (VoIP), video-

conferencing and multimedia must all be delivered to the end-users. Some of the traffic, such as video-

conferencing, is of a higher priority, with a slight delay of packets resulting in noticeable degeneration

of video and audio quality, while other traffic, such as email will not be noticeably affected by tiny

delays. The large number of programs that run over today’s networks serves to impede the ability to

deliver time-critical data. Even if bandwidth is not usually a problem on your network, during peak

hours bursts in network traffic can result in the delay of time-critical traffic.

IEEE802.1p defines seven levels of prioritization for Ethernet packets. High priority packets will be

sent through a network using 802.1p-compliant switches first. Lower priority packets will be
