Use this screen to either add or drop a member from a specified VLAN. Press APPLY when finished with all your changes.

Configure IEEE 802.1Q VLANs

To configure an IEEE 802.1 port-based VLAN, you must do three things:

1.Decide if you want to enable Ingress Filtering and enable it on the chosen ports. Ingress filtering applied on a port causes the port to examine all incoming packets and check whether the port itself is a member of the VLAN. This is normally used to keep untagged frames off the Switch, although it can have other uses as well. This setting is configurable for each port in the Configure Port Ingress Filter screen.

2.Define which ports will be active members of the VLAN. A port can transmit packets onto only one VLAN. It can receive packets (be a passive member) on many VLANs. Active VLANs are designations are defined by assigning Port VLAN ID numbers (PVIDs) in the Configure Port VLAN ID screen.

3.Define the VLAN itself and which ports will be members (able to receive packets from a port that has this PVID number). At this point, you need to designate whether a member port will be a Tagging or Untagging member port. Defining the ports that will be members of a VLAN, and whether they will Tag or Untag packets is done in the Configure Static VLAN Entry screen.

4.Determine whether to enable GARP VLAN Registration Protocol (GVRP) in order to update dynamic registration entries as well as to communicate information to other VLAN-aware workstations and bridges, thus allowing orders to issue and revoke VLAN membership. GVRP can be enabled for individual ports on the GVRP Configuration screen.

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.
