The xStack DGS-3400 series of next generation switches delivers
performance, flexibility, security, multi-layer Quality of Service (QoS)
and redundant power option for the SMB and enterprises. With high
Gigabit port densities for desktop connections, SFP fiber connectivity,
10-Gigabit uplink options and enhanced Layer 2+ functions, these
switches comprise the workgroup access-layer stack for seamless
integration with L3 core switches to form part of a multi-level network
structured with high-speed backbone and centralized servers.
Any switch in the
DGS-3400 series can operate as a stand-alone device or part of a
scalable stack. Embedded with Single IP Management capability, a
stand-alone switch can form part of a virtual stack, where intra-stack
traffic flows through the usual network wires, doing away with the
costly stacking cables. Without stacking cables, cable distance barriers
and physical stacking limitations, a virtual stack can comprise units
that are located anywhere on the network that minimizes the impact of
any single point of failure.
Redundant Ring Stacking.
Alternatively , optional 10-Gigabit
modules can be installed in the open slots to create a physical stack.
Up to 12 units or 576 Gigabit ports can be configured 1 for a stack.
Users can install one or two single-port modules, depending on whether
the linear or fault-tolerant Ring stacking is implemented. With each of
these ports providing 20Gbps full duplex transmission on the
cost-effective coaxial cable, the DGS-3400 series provides not only
high-bandwidth stacking but also cost control capability that allows
users to add ports strictly on a per need basis. Modules with single
10-Gigabit XFP can also be installed in any of the open slots for uplink
to servers or a fiber backbone.
More Intelligent Than Simple Layer 2 Switches.
DGS-3400 series provides a complete set of security features, which
includes L2/L3/L4 multi-layer Access Control Lists and 802.1x user
authentication via TACACS+ and RADIUS servers. In addition, it offers
suppression capabilities and Layer 3 IP v.4/v .6 Static Routing to
increase network performance and security. Built-in D-Link ZoneDefense
technology allows business to integrate the switch stack with D-Link
NetDefend firewalls to implement a full coverage, proactive security
Security, Performance & Availability.
DGS-3400 series provides extensive VLAN support including GARP/GVRP and
802.1Q VLAN to enhance security and performance. To support converged
applications including VoIP , ERP, Intranet and video conference, a
robust set of L2/L3/L4 QoS/CoS features ensures that critical network
services are served with proper priority. For prevent malicious flooding
traffic caused by worm/virus infections, the DGS-3400 series provides
D-Link Safeguard Engine to increase the switch's reliability,
serviceability and availability. Bandwidth Control can be flexibly set
for each port using pre-defined thresholds to assure a committed level
of service for end users. For advanced applications, per-flow bandwidth
control allows easy fine-tuning of service types based on specific IP
addresses or protocols.
