Robust Layer 2 Features
The Managed Switch can be programmed for advanced switch management functions such as dynamic port link aggregation,
802.1Q VLAN and Q-in-Q VLAN, Multiple Spanning Tree protocol (MSTP), loop and BPDU guard, IGMP snooping, and
MLD snooping. Via the link aggregation, the Managed Switch allows the operation of a high-speed trunk to combine with
multiple ports, and supports fail-over as well. Also, the Link Layer Discovery Protocol (LLDP) is the Layer 2 protocol
included to help discover basic information about neighboring devices on the local broadcast domain.
Efficient Traffic Control
The Managed Switch is loaded with robust QoS features and powerful traffic management to enhance services to
business-class data, voice, and video solutions. The functionality includes broadcast/multicast storm control, per port
bandwidth control, IP DSCP QoS priority and remarking. It guarantees the best performance for VoIP and video stream
transmission, and empowers the enterprises to take full advantage of the limited network resources.
Powerful Security
The Managed Switch offers comprehensive Layer 2 to Layer 4 Access Control List (ACL) for enforcing security to the edge. It
can be used to restrict network access by denying packets based on source and destination IP address, TCP/UDP ports or
defined typical network applications. Its protection mechanism also comprises 802.1x Port-based user authentication. With the
private VLAN function, communication between edge ports can be prevented to ensure user privacy. The network
administrators can now construct highly-secure corporate networks with considerably less time and effort than before.
Friendly and Secure Management
For efficient management, the Managed Switch is equipped with Command line, Web and SNMP management interfaces.
With the built-in Web-based management interface, the Managed Switch offers an easy-to-use, platform-independent
management and configuration facility.
For text-based management, it can be accessed via Telnet and the console port.
By supporting the standard SNMP protocol, the switch can be managed via any SNMP-based management software.
Moreover, the Managed Switch offers secure remote management by supporting SSHv2, TLSv1.2 and SNMP v3 connections
which encrypt the packet content at each session.
Flexible Long-distance Extension Solution
The two/four mini-GBIC ports built in the Managed Switch support SFP auto-detection and dual speed as it features
100BASE-FX and 1000BASE-SX/LX SFP (small form-factor pluggable) fiber transceivers to uplink to backbone switch and
monitoring center in long distance. The distance can be extended from 550 meters to 2 kilometers (multi-mode fiber) and to
10/20/40/60/80/120 kilometers (single-mode fiber or WDM fiber). They are well suited for applications within the enterprise data
centers and distributions.
Intelligent SFP Diagnosis Mechanism
The Managed Switch supports SFP-DDM (Digital Diagnostic Monitor) function that can easily monitor real-time parameters of
the SFP for network administrator, such as optical output power, optical input power, temperature, laser bias current, and
transceiver supply voltage.
