Port Settings

Figure 7-2. Port Settings window

Select the port you want to configure by clicking on the port in the Switch front panel display at the top of the window. Follow these steps:

1.Enable or disable the port. If you choose Disabled, devices connected to that port cannot use the Switch, and the Switch purges their addresses from its address table after the MAC address aging time elapses. The Switch won't purge addresses if you define them as permanent entries in the MAC Forwarding Table.

2.Configure the Speed/Duplex setting for the port. Select Auto-Negotiateto allow the port to select the best transmission speed, duplex mode and flow control settings based on the capabilities of the device at the other end. The other selections allow you to force the port to operate in the specified manner. Select 100Mbps/Full for port operation at 100 Mbps and full duplex. Select 100Mbps/Half for port operation at 100 Mbps and half duplex. Select 10Mbps/Full for port operation at 10 Mbps and full duplex. Select 10Mbps/Half for port operation at 10 Mbps and half duplex.

3.Configure the Flow Control setting for the port. Selecting Enabled in full-duplex mode will implement IEEE 802.3x flow control. Selecting Enabled when the port is in half-duplex mode will implement normal Ethernet collision-based backpressure flow control. Select Disabled for no flow control. Also, if the port is set for Auto (NWay) in the speed/duplex field above and flow control is enabled, flow control (whether full- or half-duplex) will only be implemented if the other device can auto-negotiate flow control. Note that you must reboot the Switch before a flow control change can take effect.

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.
