Robust Layer 2 Features
The SGSW-2840 can be programmed for basic switch management functions such as port speed configuration, Port
aggregation, VLAN, Spanning Tree protocol, QoS, bandwidth control and IGMP Snooping. It provides IEEE 802.1Q Tagged
VLAN and the VLAN groups allowed on the SGSW-2840 will be maximally up to 256. Via aggregation of supporting port, the
SGSW-2840 allows the operation of high-speed trunk combining multiple ports. Maximum up to 8 ports can be assigned for 12
trunk groups and it supports fail-over as well.
Excellent Traffic Control
The SGSx-series Managed Switch is loaded with powerful traffic management and QoS features to enhance services offered by
telecoms. The functionality includes QoS features such as wire-speed Layer 4 traffic classifiers and bandwidth limiting
applications that are particular useful for multi-tenant unit, multi business unit, Telco, or Network Service Provider. It also
empowers the enterprises to take full advantages of the limited network resources and guarantees the best performance in VoIP
and Video conferencing transmission.
Efficient IP Stacking Management
The SGSW-2840 supports IP Stacking function that helps network managers to easily configure up to 36 switches in the same
series via one single IP address instead of connecting and setting each unit one by one. For efficient management, the
SGSx-series Managed Ethernet Switch is equipped with console, WEB and SNMP management interfaces. With its built-in
Web-based management, it offers an easy-to-use, platform-independent management and configuration facility. It supports
standard Simple Network Management Protocol (SNMP) and can be managed via any standard-based management software
as well. For text-based management, the SGSx-series Managed Switch can also be accessed via Telnet and the console port.
Moreover, it offers secure remote management by supporting SSL and SSH connection which encrypt the packet content at
each session.
Powerful Security
The SGSx-series Managed Switc offers comprehensive Access Control List (ACL) for enforcing security to the edge. Its
protection mechanism also comprises port-based IEEE 802.1x user and device authentication. The port-security is effective in
limiting the numbers of clients pass through so that network administrators can now construct highly secured corporate
networks with considerably less time and effort than before.
Flexibility and Extension solution
The four mini-GBIC slots are compatible with 1000Base-SX/LX and WDM SFP (Small Form Factor Pluggable) fiber-optic
modules. The distance can be extended from 550 meters (Multi-Mode fiber cable) or up to 10/30/50/70/120 kilometers
(Single-Mode fiber or WDM fiber cable). They are well suited for applications within the enterprises’ data centers and
distributions.
