User-Changeable Parameters, On the Port Level

10/100 Fast Ethernet Switch User’s Guide

♦Root Path Cost: The Root Path Cost of a Switch is the sum of the Path Cost of the Root Port and the Root Path Costs of all the Switches that the packet goes through. The Root Path Cost of the Root Bridge is zero.

♦Bridge Priority: This is a parameter that users can set. The smaller the number you set, the higher the Bridge Priority is. the higher the Bridge Priority, the better the chance the Switch will be selected as the Root Bridge.

On the Port Level

♦Root Port: Each Switch has a Root Port. This is the port that has the lowest Path Cost to the Root Bridge. In case there are several such ports, then the one with the lowest Port Identifier is the Root Port.

♦Designated Port: This is the port on each Designated Bridge that is attached to the LAN segment for which the Switch is the Designated Bridge.

♦Port Priority: The smaller this number, the higher the Port Priority is. With higher Port Priority, the higher the probability that the port will be selected as the Root Port.

♦Path Cost: This is a changeable parameter and may be modified according to the STA specification. The 100Mbps segment has an assigned Path Cost of 10, and each 10Mbps segment has an assigned Path Cost of 100, based on the STA specifications.

User-Changeable Parameters

The factory default setting should cover the majority of installations. However, it is advisable to keep the default settings as set at the factory; unless, it is absolutely necessary. The user changeable parameters in the Switch are as follows:

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.
