Intelligent Multilayer Gigabit Ethernet Switch
- ZyXEL GS-4000 series is an intelligent Gigabit multilayer
(L2/L3/L4) Ethernet switch that provides enterprise-class
availability, resilient and redundant architecture with
OSPF, VRRP, RSTP and port trunking. The GS-4000 series
offers many advanced features to make it the preferred
choice for real-routing network in the enterprise. Advanced
functionalities like QoS, rate-limiting, rule-based
access control lists, multicasting support, wire-speed,
high-performance IP routing and simplified management
software (iStacking) highly improve network operation.
High-Performance Wire-speed Switching and IP Routing
- The GS-4000 series consists of two switches: the
GS-4024 with 20-port 100/1000BASE-T RJ-45 and four dual-personality
GbE interface (RJ-45 or SFP), the GS-4012F with 8-port
SFP open slots and four dual-personality GbE interface
(RJ-45 or SFP). Base on non-blocking switching architecture,
the GS-4000 series can be deployed as both an intelligent
access layer switch for enterprise wiring closets and
as a Layer 3 backbone switch for SMB networks. The GS-4000
series delivers wire-speed full-dynamic IP routing,
like OSPF and RIP using a hardware-based IP routing
engine and sophisticated multilayer operating software.
In addition to dynamic IP multicast, the GS-4000 series
supports Distance Vector Multicast Routing Protocol
(DVMRP) and Internet Group Management Protocol (IGMP)
snooping to perfectly handle a variety of datagrams
making the ZyXEL GS-4000 series ideal for today?s multi-service
network environment.
iFlow - Advanced QoS for Significant Service
- The GS-4000 series works with ZyXEL exclusive iFlow
technology, a set of advanced QoS mechanisms, to insure
noteworthy service, and smooth operation via a series
of QoS processes to prevent customers?networks being
negatively impacted by network congestion. With intelligent
multilayer capability, the GS-4000 series offers wire-speed
flow control which can classify, police, and prioritize
the incoming packets according to predefined QoS policies.
In classification, Differentiated Services Code Point
field (DSCP) and the 802.1p class of service (CoS) field
are identified to assess the priority of incoming packets.
Classification and reclassification can be based on
criteria as specific as rule-based on IP, MAC addresses,
VLAN ID,TCP/UDP port number, on the other hand, for
bandwidth management, the GS-4000 series is loaded with
powerful traffic management tools. For instance, the
GS-4000 series provides eight priority queues per port
for different types of traffics, allowing administrators
to set rule-based rate limiting which takes full advantage
of limited network resources and guarantees the best
performance.
iSafe - High-Security for Business-Critical Applications
- The GS-4000 series works with iSafe intelligent
3-tiers security which offers complete data security
in the data and management plane via a wide range of
security features to protect users?data and administrative
traffic, and secure the network from unauthorized users.
802.1x authentication and Port security provide the
ability to deny unauthorized users from accessing the
network. Limited MAC Number by Port limits the total
number of devices connected to a switch port, therefore
highly reducing the risk of unknown access from mass
deployed wireless networks or Hubs. Cooperating with
RADIUS, 802.1x is useful to prevent unauthorized access
based on username and password (or other credentials)
and acts as powerful access control for convergent networks
with mixed wired and wireless access.
The GS-4000 series multilayer (L2/L3/L4) ACLs suite
of sophisticated rule-based control mechanisms is easily
deployed, based on realistic network environments via
a Web GUI or command line to prevent abnormal and illegal
access. The rules can be defined to deny packets based
on source and destination MAC addresses, IP addresses,
or TCP/UDP ports.
iManage - Enterprise-class Network Management
- The GS-4000 series works with iManage intelligent
network management tool kits. Compared with conventional
bounded network management, ZyXEL GS-4000 series demonstrates
its power with advanced management capabilities; such
as ZyXEL-exclusive iStacking™ clustering management
technology that can cross different floors and routing
domains to locate other iStacking-capable switches in
the same management cluster, thus allowing administrators
to manage 24 switches with one single IP. This greatly
reduces operating costs and offers more flexible maintenance
of ZyXEL Switches. IT staff can opt for the Web or command
line interface to suit their needs, and even encrypt
their instructions with SSHv1/v2 and SSL/TLS. With these
sophisticated functionalities, the IT staff is empowered
to build a highly secure and efficient corporate network
with minimum effort.
