24-port NWay Ethernet Switch User’s Guide

The first setting allows you to enable or disable port auto-partitioning by the Port Auto-Partition Capability on All ports function. If you enable auto-partitioning on all ports, when more than 63 collisions occur while a port is transmitting data, the port automatically stops transmissions. The second setting allows you to enable or disable the Head of Line (HOL) Blocking Prevention function, which is designed to prevent forwarding a packet to a “blocking” port. Click Apply to let your changes take effect.

The information in the window is described as follows:

♦Port Auto-Partition Capability on All ports This option offers Enabled or Disabled to decide whether to auto-partition a selected port and take it offline or not.

♦Head of Line (HOL) Blocking Prevention This option prevents forwarding a packet to a port where an excess of packets are queued up. Note that when a multicast packet or a packet with an unknown destination address needs to be forwarded to several ports, and if some of them are “blocking,” the packet will not be discarded, rather it will be forwarded only to the ports that are not “blocking.”

Filtering and Forwarding Table

When a packet hits the Switch, it looks in the filtering and forwarding table to decide what to do with the packet; either to filter it off the network, or to forward it through the port on which its destination lies.

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.
