24-port NWay Ethernet Switch User’s Guide

To access the Custom Forwarding Table, choose Configure Filtering and Forwarding Table from the Configuration menu. Then select Configure Permanent Address Table Entry from the bottom of the Configure Filtering and Forwarding table screen. The following screen appears:

Figure 6-21. Static Forwarding Table screen

By mapping a MAC address to a destination port, the Switch can permanently forward traffic for a specified device through a specific port, even after long periods of network inactivity or during times of network congestion.

The following fields at the top of the screen can be set:

♦Action Choose to Add or Remove an entry from the table.

♦MAC Address A total of ten destination addresses per page will be seen. The Switch can hold up to 96 entries. This is the MAC address of the device that you are creating a permanent forwarding address for.

♦Port Heading a port number will be displayed for each corresponding destination address. The Switch will always forward traffic to the specified device through this port.

♦VLAN This setting only appears when Port-based or IEEE 802.1Q VLANs are active and defines the VLAN ID number in the packet. Make sure the port can accept packets on this VLAN by assigning the port this VID number.

Entries, as well as Destination MAC Address, Destination Port, VLAN, and Status, all in the lower part of the screen, are read-only. The Status of the static forwarding table entry can be In use or Not apply. Not apply means that there is a static filter for the same MAC address. Static filters always take precedence over static forwarding entries. The switch will automatically upgrade the Status to “in use” once the static filter is removed.

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.
