24-port NWay Ethernet Switch User’s Guide

♦Dropped Frames The number of frames which are dropped by this port since the last Switch reboot.

♦Undersize Frames The number of frames detected that are less than the minimum permitted frame size of 64 bytes and have a good CRC. Undersize frames usually indicate collision fragments, a normal network occurrence.

♦Total errors The sum of the CRC Error, Oversize Frames, Fragments, Jabber, Late Collision, Mac Rx Error, Dropped Frames, and Undersize Frames counters.

♦Collisions The number of collision that has occurred.

Port Packet Analysis Statistics

To access the fourth item on the Traffic Statistics menu, choose Port Packet Analysis Statistics. The following table appears:

Figure 6-59. Packet Analysis Statistics table

Select the desired setting in the Ports field: 1 to 4, 5 to 8, 9 to 12, 13 to 16, 17 to 20, 21-S1P2, or Slot 2 and the

desired increment setting in the Polling Interval field: 2 sec, 5 sec, 15 sec, 30 sec, 1 min, or Suspend. Pressing CLEAR COUNTER resets the counters.

The statistic counters displayed are defined as follows:

♦64, 65-127, 128-255, 256-511, 512-1023, 1024-1518The number of good frames of various length ranges, both valid and invalid.

♦RX (GOOD) The number of good frames received. This also includes local and dropped packets.

♦TX (GOOD) The number of good frames sent from the respective port.

♦Total RX The number of frames received, good and bad.

♦TX Octets The number of good bytes sent from the respective port.

♦RX Octets The number of good bytes received. This also includes local and dropped packets.

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.
