24-port NWay Ethernet Switch User’s Guide

Figure 6-13. Port Configuration screen

Items in the above window are defined as follows:

♦Port Specifies the port (1-22,all) that will be configured. When all is chosen, the settings you configure will be applied to all UTP ports.

♦State Enables or disables the port. This amounts to turning the port on or off.

♦Speed/Duplex Selects the desired Speed and Duplex fort the port. Possible settings include: Auto, 100M/Full, 100M/Half, 10M/Full, or 10M/Half. Choosing Auto enables NWay auto-configuration on the port.

♦Flow Control Toggles flow control On or Off. Flow control can only be used with other IEEE 802.3x-compliant devices and in a full-duplex connection. It is useful during periods of heavy network activity when the Switch’s buffers can receive too much traffic and fill up faster than the Switch can forward the information. In such cases, the Switch will intervene and tell the transmitting device to pause to allow the information in the port buffer to be sent. When Auto-Negotiation is enabled in the Speed/Duplex field above, flow control will only be enabled if the connected device can Auto-negotiate flow control. Confirm that Flow Control is in force by checking the Status field.

♦Priority Selects Normal, High or Low. The Switch has two packet queues where incoming packets wait to be processed for forwarding; a high priority and low priority queue. The high priority queue should only be used for data in which latency can have adverse affects on the function of an application, such as video or audio data, where latency can produce distorted sounds and images. Packets in the low priority queue will not be processed unless the High priority queue is empty. Setting the port priority to high will deliver all packets arriving at the port to the high priority queue, a low setting will send them all to the low priority queue. The Normal settings causes the port to examine the packet for an IEEE 802.1p/Q priority tag. If no tag exists, the packet will be sent to the low priority queue. If the priority tag field in the packet header contains a value of 0-3, the packet will be placed in the low priority queue; a value of 4-7 causes the packet to be placed in the high priority queue.

DES-3225G specifications

The D-Link DES-3225GF and DES-3225G are both robust Ethernet switches designed to meet the networking needs of small to medium-sized enterprises and organizations. These devices are part of D-Link's comprehensive range of unmanaged layer 2 switches, known for their reliability and ease of use.

The DES-3225GF features a total of 25 Ethernet ports, including 24 10/100Base-TX ports and 1 Gigabit SFP slot, while the DES-3225G also comes with 25 ports but includes 24 10/100/1000 Mbps copper ports. Both models support Auto-MDI/MDI-X for seamless connection setup without the need for crossover cables, simplifying the deployment process.

One of the standout features of these switches is their wire-speed performance that enables high-speed data transfers and efficient traffic management. Each port is designed to provide non-blocking switching, which ensures that the bandwidth is fully utilized without any packet loss. The switches support IEEE 802.3x flow control, which helps to manage data flow and prevent overflow during heavy traffic periods.

The DES-3225GF and DES-3225G offer users a simple yet efficient way to expand their network. With a plug-and-play design, they require minimal configuration, allowing for quick integration into existing network infrastructures. These switches are equipped with a durable chassis, ensuring they can withstand the rigors of a busy IT environment.

Both models boast energy-efficient technologies that comply with IEEE 802.3az, which helps in reducing power consumption during periods of inactivity. By detecting link status and adjusting power accordingly, these switches contribute to a more sustainable networking solution.

In terms of form factor, the DES-3225GF and DES-3225G are rack-mounted, making them suitable for integration into standard network cabinets. This design ensures that the devices can be efficiently managed alongside other network equipment.

For management and security, the switches support features such as VLAN tagging and port security, allowing network administrators to segment traffic and protect the network from unauthorized access. With their sturdy build, innovative features, and straightforward implementation, the D-Link DES-3225GF and DES-3225G are ideal choices for organizations looking to enhance their network performance while keeping costs manageable.
