Advanced Management Features

NXESD 1224X2 supports SNMP version 1. SNMP is a useful tool in managing and controlling SNMP-supported network devices. SNMP enables the Web Smart™ NXESD 1224X2 to be polled to provide valuable information about the status of the unit and send traps on abnormal events. This sharing of vital management information saves time and money.

The NXESD1224X2 also supports spanning tree and provides protection from unintentional cabling loops forming within a network infrastructure. 802.1D spanning tree detects and breaks these loops, ensuring network uptime.

Advanced Security

NXESD 1224X2 provides a robust set of security features normally found only in fully managed switching solutions. It is equipped with the D-Link® Safeguard Engine™ to protect the CPU from malicious attack. When frames enter the switch, the D-Link® Safeguard Engine™ detects and blocks broadcast, multicast and unicast flooding that can overload a CPU and bring network traffic to a halt.

In addition the NXESD 1224X2 also provides support for secure, encrypted 802.1x port-based user authentication, broadcast storm control and up to 256 static MAC address entries.

IEEE 802.1Q VLAN Tagging

A VLAN (Virtual LAN) is a collection of computers that are grouped together. VLANs allow the network to be segmented into groups (departmental, hierarchical, and security groups). 802.1Q is a standard that places a tag in a frame identifying which VLAN it belongs to. The advantage of this is that all 802.1Q-compliant devices can work seam-lessly together to manage VLAN traffic.

D-Link® Green Eco-Friendly Technology

D-Link® Green Technology implements special power-saving features that detect link status/cable length, and adjust power usage accordingly. The result is reduced power consumption, less heat dissipation, extended product life and reduced operating costs.

802.1p Priority Tagging

Like 802.1Q VLAN tagging, 802.1p places a tag in a frame to indicate the priority of the frame. This differs from port-based QoS in that all traffic entering a specific port in port-based QoS is prioritized the same way with the same value. In 802.1p, a port can receive frames with varying priority tags and classify them based on these tags. For example, a VoIP phone that supports 802.1p can assign a priority to its VoIP traffic. When it enters the switch, the switch can then prioritize it so that voice traffic is always clear/jitter-free.

  • Advanced security
  • IEEE 802.1Q VLAN tagging
  • D-Link® Green eco-friendly technology
  • 802.1p priority tagging
  • Jumbo frame support:
    • Designed to improve network throughput and significantly reduce the CPU utilization of large file transfers (such as multimedia files or large data files) by enabling more efficient, larger payloads per packet.
    • The NXESD1224X2 sup-ports jumbo frames up to 10 KB in size.
  • Web management utility:
    • NXESD 1224X2 includes the D-Link® Web Smart™ management utility. This utility provides a valuable tool in managing, planning and troubleshooting network configurations.
    • Managing a Web Smart™ switch takes only minutes.
    • With full-color graphic pictures, diagrams and easy-to-understand navigation menus, using the Web Smart™ management utility is as easy as surfing the Internet.
