Fragments Counts packets less than 64 bytes with either bad framing or an invalid CRC. These are normally the result of collisions.

Jabber Frames Counts frames with length more than 1518 bytes and with CRC error or misaligned (bad framing).

Collision Counts collisions on the Ethernet segment.

Late Collisions The number of collisions that occurred at or after the 64th byte (octet) in the frame.

Bytes Tx Counts the number of bytes successfully sent from the port.

Bytes Rx: Counts the number of bytes successfully received at the port. This also includes local and dropped packets.

Total Octs Rx: Counts the number of bytes (octets) received on the port, in both good frames and error frames.

Multicast Rx Frames Counts the number of good multicast frames received. This includes local and dropped multicast packets.

Broadcast Rx Frames Counts the number of good broadcast frames received. This includes local and dropped broadcast packets.

Rx (Good) Frames Counts the number of good frames received. This also includes local and dropped packets.

Tx (Good) Frames Counts the number of good frames sent from the respective port.

64 Octs, 65-127 Octs, 128-255 Octs, 256-511 Octs, 512-1023 Octs, 1024-1518 Octs Counts frames of various length ranges, both valid and invalid.

Total Rx Frames Counts the number of frames received, both good frames and error.

DES-2218 specifications

The D-Link DES-2218 is a robust and versatile 18-port Layer 2 managed switch designed for businesses seeking to enhance their network performance and reliability. With a combination of advanced features and reliable technologies, the DES-2218 offers a powerful solution for managing network traffic efficiently.

One of the standout features of the DES-2218 is its advanced Layer 2 switching capabilities. The switch supports a variety of network protocols, making it suitable for various business applications. The 18 ports, which include 16 10/100 Mbps Fast Ethernet ports and 2 Gigabit SFP slots, provide flexibility for both copper and fiber optic connections, allowing organizations to implement a tailored network infrastructure according to their specific needs.

The switch also incorporates VLAN (Virtual Local Area Network) support, enabling the segmentation of traffic for improved security and performance. This feature allows network administrators to isolate sensitive data and create efficient, manageable traffic flows that enhance overall network efficiency. Furthermore, the DES-2218 supports 802.1Q VLAN tagging, which is essential for implementing VLANs in larger, more complex networks.

In addition to VLAN capabilities, the DES-2218 offers robust Quality of Service (QoS) features. These QoS functionalities prioritize network traffic, ensuring that critical applications receive the bandwidth they need for optimal performance. This is particularly beneficial for businesses that rely on video conferencing, VoIP services, or other real-time communications.

Another notable characteristic of the D-Link DES-2218 is its support for network management protocols such as SNMP (Simple Network Management Protocol), RMON (Remote Monitoring), and WEB Management. These features enable administrators to remotely monitor and manage the network, ensuring that any potential issues can be addressed before they impact business operations.

Security is another priority in the design of the D-Link DES-2218. The switch supports various security features, including port security and MAC address filtering, which help protect the network from unauthorized access and ensure that only legitimate users can connect.

Overall, the D-Link DES-2218 is an feature-rich managed switch that combines essential technologies and characteristics to deliver a reliable networking solution for businesses of all sizes. With its extensive management capabilities, enhanced security measures, and advanced VLAN and QoS support, the DES-2218 is an ideal choice for organizations looking to optimize their network performance.
