DES-7200 Hardware Installation Guide
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 t o
create VPNs a nd pr ovide link s election, while the i nner l ayer I Ds ar e used to i dentify 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 i n t he 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,
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 m ainstream 10-Gigabit LAN t ransmission s tandards s uch as
10GBASE-R and 10GBASE-W.
Supporting the PoE technology

DES-7200 provides c able cards s upporting P oE. P oE des ign c ompletely c onforms t o t he
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 t o 384 f ast E thernet p orts, 192 10 00M optical f iber p orts 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.
