Intelligent SFP Diagnosis Mechanism

The GS-5220-44S4C supports SFP-DDM (Digital Diagnostic Monitor) function that greatly helps network administrator to easily monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.

IPv6 / IPv4 Dual Stack

Supporting both IPv6 and IPv4 protocols, the GS-5220-44S4C helps the data center / campus / telecom to experience the IPv6 era with the lowest investment as its network facilities need not to be replaced or overhauled if the IPv6 FTTx edge network is set up.

Layer 3 IPv4 and IPv6 VLAN Routing for Secure and Flexible Management

The GS-5220-44S4C switch not only provides ultra high transmission performance, and excellent layer 2 and layer 4 technologies, but also layer 3 IPv4/IPv6 VLAN routing feature which allows to cross over different VLANs and different IP addresses for the purpose of having a highly-secured, flexible management and simpler networking application.

Robust Layer 2 Features

The GS-5220-44S4C can be programmed for advanced switch management functions such as dynamic port link aggregation, Q-in-Q VLAN, private VLAN, Multiple Spanning Tree protocol (MSTP), Layer 2 to Layer 4 QoS, bandwidth control and IGMP/MLD Snooping. Via the link aggregation of supporting ports, the GS-5220-44S4C allows the operation of a high-speed trunk to combine with multiple fiber ports and supports fail-over as well.

Powerful Security

The GS-5220-44S4C offers a 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 and MAC-based user and device authentication. With the private VLAN function, communication between edge ports can be prevented to ensure user privacy. The GS-5220-44S4C also provides DHCP Snooping, IP Source Guard and Dynamic ARP Inspection functions to prevent IP snooping from attack and discard ARP packets with invalid MAC address. The network administrators can now construct highly-secured corporate networks with considerably less time and effort than before.

Excellent Traffic Control

The GS-5220-44S4C is loaded with powerful traffic management and QoS features to enhance connection services by SMBs. The QoS features include wire-speed Layer 4 traffic classifiers and bandwidth limit that are particular useful for multi-tenant unit, multi business unit, Telco, or network service provider’s applications. It also empowers the enterprises to take full advantage of the limited network resources and guarantees the best performance in VoIP and video conferencing transmission.

Efficient and Secure Management

With built-in Web-based management interface, the GS-5220-44S4C L2+ Managed Switch offers an easy-to-use, platform-independent management and configuration facility which includes Console, Web and SNMP management interfaces. The Simple Network Management Protocol (SNMP) can be managed via any management software based on standard of SNMP protocol. For reducing product learning time, it offers Cisco-like command via Telnet or console port and customer doesn’t need to learn new console command. Moreover, it also offers secure remote management by supporting SSH, SSL and SNMPv3 connections which encrypt the packet content at each session.
