10/100 Fast Ethernet Switch User’s Guide

discarding unwanted addresses from the Forwarding Table; furthermore, you can use it for explicit forwarding by speeding up the process of packet forwarding.

Dynamic Filtering and Static Filtering are among the two important features of the Custom Filtering Table. They are defined here briefly as follows. Dynamic Filtering is defined when a dynamic entry is created by the Learning Process as a result of observation of network traffic in the Filtering Database. Static Filtering is defined as static entries that may be added and removed from the Filtering Database by the user. They are not automatically removed by any timeout mechanism.

The Source Address heading displays a total of ten (10) addresses at a time; while a total of 40 MAC addresses may be inputted for all of the ports. The Source Port heading displays the respective port you would like associate with an inputted Source Address.

Occasionally you may want to manually add entries to the switch’s forwarding table. To add an entry for a station,

1.Choose Spanning Tree Algorithm Parameters from the main menu.

2.Choose Custom Filtering Table.

DES-3208 specifications

The D-Link DES-3208 is a robust and reliable Layer 2 Fast Ethernet unmanaged switch designed to enhance networking capabilities in both small and medium-sized businesses. With a compact and efficient design, the DES-3208 offers seamless connectivity for various devices, ensuring speedy data transfers and enhanced network performance.

One of the key features of the DES-3208 is its 8 Fast Ethernet (10/100 Mbps) ports, which allow for easy expansion of network infrastructure. The switch operates on a non-blocking architecture, which means it can handle multiple data streams simultaneously without compromising performance. This is particularly beneficial in environments where high traffic and data-intensive applications are commonplace.

The DES-3208 supports auto-MDI/MDIX functionality, which eliminates the need for crossover cables as the switch automatically detects the cable type connected. This feature simplifies network setup and allows for flexible configurations, enhancing usability for IT managers and system administrators.

Power-saving technologies are also a hallmark of the D-Link DES-3208. It features innovative Green Ethernet technology that reduces power consumption by detecting inactive ports and adjusting power usage accordingly. This not only contributes to environmental initiatives but also provides cost savings on energy bills over time.

Additionally, the switch supports a variety of network protocols to ensure compatibility with different network environments. These features include IEEE 802.3x flow control, which helps prevent packet loss during data transmissions, and IEEE 802.1p prioritization, ensuring critical traffic is processed in a timely manner.

The fanless design of the DES-3208 contributes to silent operation, making it an ideal choice for office environments where minimal noise is preferred. The compact form factor further allows for easy placement either on a desk or in a rack mount.

Overall, the D-Link DES-3208 is a versatile and efficient solution for businesses seeking an unmanaged switch that balances performance, energy efficiency, and ease of use. It adeptly meets the needs of growing networks while providing essential features that promote reliability and connectivity.
