10/100 Fast Ethernet Switch User’s Guide

Parameters in this screen are described in the following table.

Field

Description

TX Packet Count

The number of packets that have been

 

transmitted successfully by the selected port.

 

Packets are from 64-1518 bytes, including the

 

CRC.

RX Byte Count

The size, in bytes, of all packets received and

 

forwarded successfully by the selected port.

RX Packet Count

The number of packets that have been received

 

successfully on the selected port.

RX Broadcast

The number of broadcast packets that are

PKT

received.

RX Multicast

The number of multicast packets that are

PKT

received.

RX Reject Count

The number of discarded packets that are

 

received on the selected port. These frames

 

are discarded at the receiving port because of

 

frame filtering.

RX Drop Event

The number of lost packets received on the

Count

selected port. Lost packets result from the lack

 

of internal receive buffer space.

FCS Error Count

The number of packets with cyclic redundancy

 

check (CRC) errors that are received on the

 

selected port.

Alignment Error

The number of alignment errors received on the

PKT

selected port. An alignment error occurs when

 

a received packet is not an integral number of

 

bytes.

Under Size PKT

The number of packets received that were well

 

formed but less than 64 bytes long.

Over Size PKT

The number of packets received that were well

 

formed but greater than 1,518 bytes long.

Fragment PKT

The number of packets received that were less

Count

than 64 bytes long and had either a CRC error

 

or an alignment error.

DES-1012 specifications

The D-Link DES-1012 is a robust solution that delivers reliable and efficient networking capabilities, making it ideal for small to mid-sized business environments. This 10/100 Mbps Ethernet switch is designed to provide high-performance data transfer, ensuring smooth communication within networks.

One of the primary features of the D-Link DES-1012 is its 12 10/100 Mbps Auto-Negotiation ports. These ports automatically detect the network speed of connected devices, allowing for easy and efficient integration into existing network infrastructures. The switch's plug-and-play design eliminates the need for extensive configuration or setup, making it accessible for users with varying levels of technical expertise.

The DES-1012 supports various network technologies, enhancing its versatility in different environments. It uses (Store-and-Forward) switching, which ensures the integrity of data being transmitted by checking for errors before forwarding packets. This feature is essential in minimizing data loss and ensuring reliable communication between devices. Additionally, the switch offers full-duplex communication, allowing data to be sent and received simultaneously, effectively doubling the bandwidth and improving overall network performance.

Energy efficiency is another key characteristic of the D-Link DES-1012. The switch is designed to reduce power consumption without compromising performance, making it an environmentally friendly choice for businesses looking to lower their energy costs. It achieves this through features like IEEE 802.3az Energy Efficient Ethernet, which intelligently manages power usage based on the amount of network traffic.

Furthermore, the D-Link DES-1012 incorporates QoS (Quality of Service) functionality, prioritizing critical applications and ensuring that bandwidth for voice, video, and data traffic is managed effectively. This feature is particularly beneficial in scenarios where real-time communication is vital, such as VoIP calls and video conferencing.

In conclusion, the D-Link DES-1012 is a well-rounded Ethernet switch that combines efficiency, performance, and ease of use. Its 12 ports, support for essential networking technologies, commitment to energy efficiency, and QoS functionality ensure that it meets the demands of modern business networks. Whether for expanding existing networking capabilities or establishing new ones, the DES-1012 proves to be a reliable choice.
