xStack

The Ultimate Stackable Alternative to Meet Your Chassis Requirements

D-Link ' s next-generation switches xStacks are high port-density Layer 3 stackable switches that combine the ultimate

performance with fault tolerance, security, management functions with flexibility and ease-of-use. All these features typically

found in the more expensive chassis-based solutions, at the price of a stackable!

Fault Tolerant Star Stacking

10G Uplinks 10 Times the Speed of Gigabit*

Each D-Link xStack switch is equipped with 2 stacking ports

providing 20Gbps full duplex bandwidth. Up to 6 xStack

switches can be stacked with a Stacking Master, itself equipped

with 6 stacking ports providing 120Gbps aggregated stacking

bandwidth. Star stacking provides fault tolerance, and switch

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.

D-Link xStack provides the 10G uplinks for transmission at 10

times the speed of a Gigabit port. The 10G uplinks are available

as optional modules each equipped with 2 XFP compliant slots,

into which you can install 2 IEEE 802.3ae-compliant XFP

transceivers for data transmission at 20,000Mbps in the full

duplex mode.

Complete Solution for Mid-Sized Businesses &

Enterprises

Whether you need to bring Gigabit or just conventional

10/100Mbps speed to your organization's desktops, D-Link

xStack has the right solution with right port types, port densities

and uplinks to match your requirements. With scalability and

flexibility built in, individual 10/100Mbps Ethernet and

10/100/1000Mbps Gigabit units may be joined in any

combination to evolve with your network needs.

Ring Stacking Topology

Shared 40Gbps stacking bandwidth in the ring topology is also

provided for installation sites with fewer switches to stack, so

you don't have to add a Stacking Master. In a ring stacking

scheme, xStack supports up to 12 units per stack. No matter if

the Star or Ring topology is employed, you can easily see the

ID number of the stacked units from the 7-segment display on

the front panel of each switch.

Wire-speed Packet Routing

D-Link xStack provides wire-speed non-blocking switch fabrics

with very fast hardware-based packet filtering/forwarding and

instant support for Windows, Unix and Internet environments.

Packet routing supports RIP v.1, v.2, OSPF and DVMRP

protocols, performed by on-board ASICs at speeds many times

faster than CPU-based routers.

High Gigabit Port-Density

D-Link's xStack provides up to 48 Gigabit ports per switch in a

low-profile 1-U rack-mount case. This gives you up to 312

Gigabit ports per stack in the star architecture, or maximum

336 Gigabit ports per stack in the ring topology. This high

Gigabit port density allows your xStack to be deployed either

as a core switch or as an easily expandable stack for Gigabit-

to-the-desktop applications.

Plug-and-Play Configuration

Enhanced Network Performance & Availability

The xStack simplifies and speeds up your management tasks, as

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 comprehensive

management and configuration tasks, eliminating the need for you to

install expensive, complex SNMP network management software.

D-Link's xStack provides extensive VLAN support including

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 xStack supports redundant power option to maximize network

uptime. Other features include 802.3ad Link Aggregation, 802.1d

Spanning Tree and 802.1w Rapid Spanning Tree to increase network

reliability and availability of your stack.

Easy Expansion Beyond Your xStack

Multi-layer Quality of Service (QoS)

With D-Link SIM (Single IP Management) support*, you can easily

add up to 32 switch units per stack outside of your xStack that are

not limited to any specific models. Through the built-in web

manager, you can have a Tree View with clear information about the

members of the stacks, and your Network Topology that shows the

locations of the stacked units and their link information. Your

xStack's support for any switch models with embedded Single IP

Management means that you can expand your stack to include also

L2 access-level or any other switches to accommodate your network

growth.

The xStack 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) Support

D-Link xStack supports the Virtual Router Redundancy Protocol

(VRRP), allowing 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.

Comprehensive Security

D-Link's xStack provides a complete set of security features 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.

Extensive Network Management Functions

The xStack supports a variety of network management options

including: console CLI, Telnet configuration, web-based and SNMP

v.1, v.2c, v.3 management, RMON monitoring, TFTP firmware

upgrade, Port Mirroring for troubleshooting, Bootp and DHCP IP

assignment. The xStack also supports a variety of advanced traffic

management options including: 802.1x, Bandwidth Control,

Broadcast Storm Prevention, and support for IGMP v.1, v.2 snooping.
