24-port NWay Ethernet Switch User’s Guide

The lower part of the screen is a read-only Browse Address Table that contains Port, MAC Address, Learned status, and the VLAN number of each entry. Use N to advance to the next page and P to return to the previous page.

Browse IGMP Status

The Browse IGMP Status function allows you to browse Internet Group Management Protocol (IGMP). The Switch is able to recognize IGMP queries and reports sent between stations and an IGMP router. When enabled for IGMP snooping, the Switch can open or close a port to specific devices based on the IGMP messages sent from the device to the router or vice versa.

To display the IP Multicast Information screen, choose Network Monitoring from the main menu and then choose Browse IGMP Status. The following screen appears:

Figure 6-61. IP Multicast Information screen

This screen displays the number of IGMP queries and reports for each active IP multicast group detected by the Switch. You can also view which Switch ports support each multicast group.

The fields displayed are defined as follows:

IGMP Snooping Indicates whether IGMP snooping is Enabled or Disabled.

Age-out Timer Displays the time the Switch waits between IGMP queries.

VLAN The selected VLAN.

Multicast Group The Multicast IP address of the Multicast group being displayed.

MAC Address The Multicast MAC address of the multicast group being displayed.

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.
