he D-Link xStack Layer 3 Gigabit switches are stackable switches that combine

T

performance with physical star stacking fault tolerance, robust security, quality of service
(QoS), versatile management functions with scalable flexibility. All these features typically
found in the more expensive chassis-based solutions, at the price of a stackable. A stack
can provide up to 312 Gigabit ports * in the star architecture, and 336 Gigabit ports ** for the
ring topology. 10Gigabit uplinks are available as optional modules, each with 2 XFP slots for
transceivers capable of transmission at 20,000Mbps in the full duplex mode.

High-Speed Stacking. Each switch is equipped with 2 stacking ports providing 20Gbps full
duplex bandwidth. Up to 6 units can be stacked with a Stacking Master, itself equipped with
6 stacking ports providing 120Gbps aggregated stacking bandwidth. Star stacking provides
fault tolerance, as units can be added or removed without interrupting the service of the
entire stack. The switches are stacked together through high-speed stack cables, allowing
the entire stack to operate as a single high-performance entity. Alternatively, for installation
sites with fewer switches to stack, shared 40Gbps ring stacking topology can be employed,
so you don't have to add a Stacking Master.

Easy Expansion Beyond Physical Stack. With D-Link Single IP Management support, you
can easily add up to 32 switch units per stack (not limited to any specific models) outside of
your physical stack. Multiple switches can be configured, monitored and maintained from
any workstation running a web browser through one single IP address. The stack is
managed as a single object, and all stacked units are identified by a single IP address. A
simple yet powerful web-based interface allows you to perform most management and
configuration tasks, eliminating the need for you to install expensive, complex SNMP
network management software.

Comprehensive Security. A complete set of security features is provided for connectivity and
access control. This set includes Access Control Lists (ACLs) based on MAC address,
switch port, IP address, and/or TCP/UDP port numbers, 802.1x user authentication and
MAC address control. The xStack also provides central management for administration
access via TACACS/TACACS+ and RADIUS. Together with network application control, this
security ensures that not only proper user access is served, but malicious traffic is also
prevented from being spread across the network. VLAN support includes GARP/GVRP and

802.1Q to enhance network security and performance. Bandwidth control allows you to set
traffic limit for each port to control the traffic volume from the edge of the network. The switch
implements a robust set of multi-layer (L2, L3, L4) QoS/CoS features to ensure that critical
network services like VoIP, ERP, Intranet and video conference are served with proper
priority. Up to 8 priority queues for 802.1p/TOS/DiffServ are supported, with classification
and marking based on MAC SA/DA, IP SA/DA, and/or TCP/UDP port numbers. Virtual
Router Redundancy Protocol (VRRP) allows several L3 switches on a multi-access link to
utilize the same virtual IP address. One switch will be elected as a master with the other
switches acting as backups in case of the failure of the master router. This VRRP support
provides convenience, permitting your host system to be configured manually or via DHCP
with a single default gateway.
