1Product Overview
1.1 Product Overview
In recent years as the Internet users grow at an explosive rate, they are no longer satisfied
with various existing ways of communications that rely largely on telephone networks, and
demand telecom operators to provide multimedia services such as voice, data, and image.
The traditional narrowband access method can no longer meet the needs for telecom
services, while the broadband access technology will bring about tremendous changes to
the life and work of the people.
Compared with the broadband access methods such as ADSL and HFC, the Ethernet
access method features such advantages as high bandwidth and low cost.
The Ethernet is the most direct way of bearing the IP service, which is the major service of
the broadband metropolitan area network (MAN). The network and users do not need to add
any other special equipment, reducing the cost in protocol conversion. In addition, the
Ethernet access method is ideal for the users densely populated in residential areas and it
accommodates the trend where optical fibers are used for the access network. Therefore,
the Ethernet gains rapid development and wide application in the broadband access field.
In this situation, D-Link Corporation introduces high-density multi-service IPv6 core router
switch DES-7200 by sparing great efforts, after the release of the multi-service 10-Gigabit
core router switch DES-7200 being applicable to the backbone Ethernet. DES-7200, as a
multi-service IPv6 10-Gigabit core router switch of the new generation, provides powerful
defense ability while ensuring high performance and large capacity. It also boasts the ability
of service addition and expansion on demand, thus satisfying the design requirements of
equal emphasis on service and performance. Currently, two models are available,
DES-7206 and DES-7210, which offer ten vertical slots and six horizontal slots respectively.
The DES-7210 series multi-service Ipv6 10-Gigabit core router switch provides users with
high-speed non-blocking data switching. With powerful switching and routing functions and
secure intelligent technologies, it can be used together with various series of D-Link
switches to provide users with complete end-to-end solutions. It is ideal for large-scale
network core backbone and heavy traffic node switch. By expanding with high-performance
multi-service cards, the DES-7200 series switches support policy routing and IPV6, and
satisfies customers’ flexible and complex application requirements.
Applications:
Core layers of such enterprise networks of educational, financial and governmental
organizations
Running environment that needs powerful routing function and carrier-class security &
reliability
High-layer switching of enterprise networks with high bandwidth and 10G needs
Enterprise environment that needs to provide high QoS assurance for various
applications

1.2 Technical Specifications of
DES-7206/7210
1.2.1 Product Features
Powerful expandability
DES-7200 supports strategic routing and IPv6. It provides faster and more effective
processing ability by expanding high-performance multi-service cards.
Hot-swappability
With a modular design, all the switching modules, management modules, power supply, and
fan tray of the DES-7200 are hot swappable, allowing modules to be replaced without first
shutdown of the system.
Redundancy configuration
The DES-7200 provides system redundancy configuration, particularly dual redundancy for
its power supply and management module, which greatly enhances system reliability and
stability.
Powerful data processing design
Complicated functions of the DES-7200 such as switching, routing, ACL, and QoS are
implemented via hardware, which avoids the impact produced by the implementation via
software on high-speed data processing.
The management module performs such functions as route management, network
management, and network service. The user interface module can independently implement
such functions as hardware routing, switching and multicast. On the other hand, the user
switching port independently implements hardware ACL and QoS. All these greatly enhance
the processing capability of the equipment as a whole.
High security assurance
Physical security:
The DES-7200 provides physical security assurance such as redundant management
modules, redundant power modules, hot-swappability of each module.
Virus and attack protection:
Responding to the increasingly more network viruses and attacks in the network
environment, the DES-7200 provides powerful network virus and attack prevention, not only
ACL, but also Source IP Spoofing prevention, among many others.
The DES-7200 provides the multiple-port synchronous monitoring technology, which
supports flexible network monitoring and offers higher monitoring capability.
Equipment management security:
To prevent non-administrators from logging in and manipulating the network equipment,
which affects network transmission and security, the DES-7200 provides the SSH encrypted
login function and the source IP restriction for telnet/web login.
Access security:
The hardware supports IP, MAC, and port binding to enhance user access control.
They support 802.1X to meet 6-element binding access restriction.
The switch supports IGMP source port check to effectively control invalid multicast sources
and improve network security.

DES-7200 Hardware Installation Guide
1-3
The PVLAN (port protection) is used to isolate the information exchanged between users,
without needing to occupy the VLAN resources.
The port MAC address lock and port MAC address access quantity restriction can bar the
access from illegal hosts.
A full range of application support techniques (QoS, multicast)
The DES-7200 provides multiple traffic classification techniques and QoS techniques,
including SP, WRR, CAR, and HOL, to provide needed techniques of bandwidth assurance
for various applications.
The DES-7200 provides multiple multicast support techniques, including IGMP snooping,
IGMP, PIM (SM, DM), and DVMRP, to ensue reasonable bandwidth occupation when
multicast services are provided in the network.
Supporting L2 VPN (VPLS)
The DES-7200 supports Service Provider VLAN (Double Tagging, VLAN tunnel), which
enables secondary VLAN identification for switched data. The outer layer IDs are used to
create VPNs and provide link selection, while the inner layer IDs are used to identify the
service VLAN function and implement L2 VPNs in the Ethernet environment, offering a
solution to the absence of data transmission security control in the traditional Ethernet
environment.
ECMP/WCMP (Equal-Cost Multipath Routing/ Weight-Cost Multipath Routing)
In the network environment where multiple links reach the same destination address, the
packets to the destination address can take only one link of them when the traditional routing
technology is used, with all other links being in the standby or inactive status. In addition, the
switching between the links takes some time in the dynamic routing environment. On the
other hand, the ECMP and WCMP can use multiple links at the same time in such network
environment. This not only increases the transmission bandwidth, but also backs up the data
transmission for the failed link without delay and packet loss.
Supporting sophisticated dual-core technology
The DES-7200 supports multiple STPs and VRRPs including 802.1D, 802.1W, and 802.1S,
offering sophisticated dual-core assurance technologies.
Providing visual status display
DES-7200 is embedded with an LCD screen, used for providing current system information
such as working time and system utilization.
Supporting the advanced 10-Gigabit Ethernet technology
DES-7200 provides current mainstream 10-Gigabit LAN transmission standards such as
10GBASE-R and 10GBASE-W.
Supporting the PoE technology
DES-7200 provides cable cards supporting PoE. PoE design completely conforms to the
requirements of the IEEE 802.3af standards.
DES-7210 provides up to 198 fast Ethernet PoE ports; DES-7206 provides up to 192 fast
Ethernet PoE ports, offering flexible network expansion for large enterprise parks.
High-density port design
DES-7210 provides up to 384 fast Ethernet ports, 192 1000M optical fiber ports and 32
10-Gigabit ports; DES-7206 provides up to 192 fast Ethernet ports, 96 1,000M optical fiber
ports and 16 10-Gigabit ports, offering flexible network expansion for large enterprise parks.

Note
This structure is designed with air inlet from the front panels of the
modules, and air outlet at the back. Six 120*120*38 fans are used to blow
the air to the outside for convection and ultimately heat dissipation.
Therefore, the chassis should be mounted at a place with adequate
spacing around for air circulation.
