Hardware-based Intelligent
Service
The Versatile Network Processing (VSNP) Service
Interface Module of Quidway S6500 series for Salience?
III and Salience? III Plus provides enhanced features.
It adds Layer 3 routing table and supports advanced
hardware-based Network Address Translation (NAT)
and NetStream as well as policy-based routing
(PBR) features.
Network Address Translation - The Quidway S6500
series can support 32 IP pools and ultimately
8,000 IP address. The Network Address Port Translation
(NAPT) enables the mapping of multiple internal
addresses to the same public address, thereby
enabling multiple internal hosts be able to access
external networks simultaneously. The Easy IP
feature will ideal when only one public IP address
is available or there are a limited number of
internal hosts. It can protect equipments against
TCP SYN and UDP port-scan attack.
NetStream - The VSNP Interface Module supports
flowbased statistics monitoring. Data can be exported,
collected and analyzed for network-traffic accounting,
network monitoring, security alarming and network
planning. It can support up to 300,000 stream
statistics entries per board. Supposed 64 bytes
per packet and single direction, the throughput
will reach to 3.8Gbps and the forwarding rate
is 5.7Mpps.
Policy Based Routing - The VSNP Service Interface
Module introduces Network Processor (NP) to guarantee
wire-speed forwarding while PBR is configured.
It can implement logical usage of bandwidth, link
backup and traffic marks. Supposed 64 bytes per
packet, the throughput will reach to 3Gbps and
the forwarding rate is 4.5Mpps.
Smoothly Upgrade and Backward Compatibility
of LPU
Newly released, the S6500 series currently has
4 models, 6 engines, and dozens of interface boards
available. All are based on advanced architecture
and can perform from access to aggregation and
the core layer.
With multiple high speed GEBUS and XGBUS between
Main Control Units and interface modules, smooth
network upgrade is guaranteed from FE to GE and
10GE. And with the GEBUS design in the new Salience?
III series super engines, all the legacy interface
boards will work with the new chassis and switching
engines. As a result, TCO (Total Cost of Ownership)
for customers is protected, and more choices are
available for customers.
Complete Security Mechanism
The Quidway S6500 series deploys the sophisticated
802.1x mode for access user authentication. 802.1x
dynamic user binding enables a switch to dynamically
bind the IP address, the MAC address, the accessing
port, and the VLAN to which the accessing port
belongs after an 802.1x user passes the authentication.
And the switch then only permits the packets that
match all these four items.
Guest VLAN allows unauthenticated users to access
more resources, without installing 802.1x client,
or the user upgrades 802.1x client without authentication.
Dynamic VLAN with RADIUS server implements the
purpose of controlling the network resources that
the users can access.
HWTACACS or RADIUS authentication or local server
enables centralized access control of switches
and limits unauthorized users to modify the configurations.
DHCP Security can be used to prevent illegal
user from accessing network by binding IP and
MAC address on the switch itself.
The Quidway S6500 series can also prevent unauthorized
access to the network by binding any combination
of MAC, IP, VLAN and PORT.
The Quidway S6500 series also support Secure
Shell (SSH) protocol version 2, secure SNMPv3
NM protocol and MD5 encrypted authentication of
OSPFv2, RIPv2 and BGPv4 packets.
Salience? III Super Engine of the Quidway S6500
series offers superior per-port QoS features to
help ensure that network traffic is classified,
prioritized, and scheduled optimally to efficiently
handle bandwidth-hungry multimedia, time-sensitive
(voice), and mission-critical applications. Salience?
III Super Engine can classify, police, and mark
incoming packets, allowing the administrator to
differentiate between traffic flows and enforce
policies. Sharing, shaping, and strict-priority
configurations determine scheduling of egress
traffic. Bandwidth control granularity is up to
64 Kbps.
Adopting the advanced system ASIC chip design,
the longest routing prefix mode and the packet-by-packet
forwarding mode, the Quidway S6500 series can
effectively combat network viruses like Worm.
Blaster, Red Code, etc.
Excellent Power over Ethernet (PoE) Solution
S6500 series switch supports IEEE 802.3af standard
PoE as PSE (Power-sourcing Equipment) on 10/100BASE-TX
or 10/100/1000 BASE-T ports.
All new PoE line cards of S6500 series switch
can support up to 48 simultaneous full-powered
PoE port per slot at 15.4w. It also supports intelligent
power management and delivers necessary power
to PD (Powered Device). It could provide up to
2400W power supply with N+1 redundancy.
In the network construction, it could provide
power directly to any IEEE 802.3af-compliant end
device to limit the number of point failure, such
as WLAN Access Point device or IP Phone which
enables Voice VLAN applications.
With PoE and Voice VLAN technology, these innovative
switches can provide the perfect solution for
a converged voice and data network.
Ethernet passive Optical Network (EPON)
Solution
The Quidway S6500 has launched Gigabit EPON
series product based on IEEE 802.3ah standard.
EPON series product includes Optical Line Terminal
(OLT), Optical Network Unit (ONU) and Passive
Optical Splitter (POS). It has abundant L2/L3
switching features and can be applied to an all
Fiber To The Home (FTTH) and Fiber To The Building
(FTTB) solution. EPON series product has unique
advantages, such as Operation, Administration
and Maintenance (OAM), dynamic bandwidth assignment
from 1Mbps to 1Gbps, and flexibly installed ONU.
Those features simplify administration and maintenance
of network, lower the cost of network ownership
and economize the fiber resources.
The Quidway S6500 can provide 44 Gigabit EPON
interfaces at most and the maximum split ratio
of POS is 1:32, so the whole chassis can access
1408 ONU. The transmission distance of EPON can
be up to 20km.

of protocols operating on network and an enhanced
alternative to the ping command.
The Quidway S6500 Series support Device Link
Detection Protocol (DLDP), DLDP can detect the
link status of the optical fiber cable or copper
twisted pair. If DLDP finds a unidirectional link,
it disables the related port automatically or
informs users to disable it manually depending
on specific configuration, to avoid potential
network problems.
The Quidway S6500 Series support Loopback detection
on ports, after users enable Loopback detection
for Ethernet ports, the switch will monitor whether
the ports have Loopback on a regular basis; if
the switch detects Loopback for a particular port,
it will put that port under control.
