Configure MAC Address Filtering

The Static Filtering Table contains filtering information configured into the Switch by (local or network) management specifying destination addresses which are not allowed to be forwarded. The Switch will check both the destination and source MAC addresses on all packets.

To access the Static Filtering Table, select Configure Filtering and Forwarding Table from the Configuration menu. Then select Configure MAC Address Filtering from the bottom of the Configure Filtering and Forwarding Table screen. The following screen appears:

Figure 6-22. Static Filtering Table screen

To make a change to the Static Filtering Table, choose Add or Remove in the Action field. Then enter the MAC Address and VLAN (if Port-based or IEEE 802.1Q VLANs are enabled) and press APPLY.

Configure IGMP Filtering

Internet Group Management Protocol (IGMP) allows multicasting on your network. When IP Multicast Filtering is Enabled, the Switch can intelligently forward (rather than broadcasting) IGMP queries and reports sent between devices connected to the Switch and an IGMP-enabled device hosting IGMP on your network. When enabled for IGMP snooping, the Switch can open or close a port to a specific Multicast group member based on IGMP messages sent from the device to the IGMP host or vice versa.

Basically, in these submenus you define whether the Switch can intelligently forward IGMP packets, and you must also define which 802.1Q VLANs (if present) can send and receive IGMP and Multicast packets.

To access the IGMP Configuration screen, choose Configure IGMP Filtering from the Configuration menu. The follow screen appears:

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.
