All of the ports can operate in either half-duplex or full-duplex mode. Full- duplex operation, allowing the port to transmit and receive at the same time, can double overall network bandwidth in many applications.

Switching

The DES-2218 uses store-and-forward technology to bridge packets between ports. Forwarding and filtering occurs at full “wire speed,” 148,800 packets per second (pps) for Fast Ethernet, and 14,880 pps for Ethernet. It has 2MB of buffer memory for the 10Mbps ports, and 4MB for the 100Mbps ports.

The switch automatically learns Ethernet (MAC) addresses and stores them in a forwarding table. In addition, it also supports static filtering, allowing network administrators to define custom filters for network security or other purposes.

The switch supports the IEEE 802.1d Spanning Tree Protocol, allowing you to design your network with redundant bridge links.

Management

You can use any network management software supporting SNMP (the Simple Network Management Protocol) to manage the DES-2218, including D-Link’s Windows-based D-View management system. The DES-2218’s internal intelligent management agent supports several standard SNMP MIBs, along with its own proprietary management information base.

SNMP management can be done in-band, over the Ethernet or Fast Ethernet network, or out-of-band, over the DES-2218’s RS-232 console port, using SLIP (the Serial Line Internet Protocol).

In addition, you can manage the switch with an easy-to-use console interface, either directly over the RS-232 console port, or over the network using the Telnet protocol.

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.
