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 s upply a nd m anagement m odule, which gr eatly e nhances s ystem reliability and
stability.
 Powerful data processing design
Complicated f unctions of t he DES-7200 such as s witching, r outing, A CL, and Q oS ar e
implemented v ia har dware, w hich avoids t he i mpact pr oduced b y t he implementation v ia
software on high-speed data processing.
The management module per forms such f unctions as r oute m anagement, net work
management, and network service. The user interface module can independently implement
such f unctions as har dware r outing, s witching and m ulticast. O n t he ot her ha nd, t he 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 t o t he i ncreasingly m ore n etwork v iruses and at tacks i n t he net work
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 m ultiple-port s ynchronous m onitoring t echnology, which
supports flexible network monitoring and offers higher monitoring capability.
Equipment management security:
To pr event no n-administrators f rom l ogging i n and manipulating t he n etwork equ ipment,
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.

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 m ultiple m ulticast s upport techniques, including I GMP snooping,
IGMP, PIM ( SM, D M), and D VMRP, t o ens ue r easonable b andwidth oc cupation when
multicast services are provided in the network.
 Supporting L2 VPN (VPLS)
The DES-7200 supports S ervice P rovider V LAN ( Double T agging, V LAN t unnel), which
enables s econdary VLAN identification f or switched data. The outer layer IDs are us ed to
create VPNs a nd pr ovide link s election, while the i nner l ayer I Ds ar e used to identify t he
service VLAN f unction and i mplement L2 VPNs i n the Ethernet environment, of fering a
solution to t he a bsence of dat a t ransmission s ecurity c ontrol in t he t raditional E thernet
environment.
 ECMP/WCMP (Equal-Cost Multipath Routing/ Weight-Cost Multipath Routing)
In t he network env ironment where m ultiple links r each t he s ame destination address, t he
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 b etween t he links t akes s ome t ime in the dynamic r outing environment. On t he
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,

Note
This structure is designed with air inlet at front/back and two sides, and air
outlet at top back and both sides. 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.
