Key Features
· High Scalability, Protecting Investments
The DH S5500 series switches have four fixed ports, which provide
users with a cost-effective 10G uplink capability while implementing
high-density 1000M access, thereby protecting user investments. The DH
S5500 series switches also support the Intelligent Resilient Framework
2 (IRF2). Nine devices can be stacked, to form a logical entity. In this
way, device capacity can be smoothly expanded along with network
development, providing users with high flexibility and expansion
capabilities.
· IRF2
The DH S5500 series switches support the IRF2 technology. Specifically,
multiple physical devices are interconnected and virtualized into one
logical device. In other words, users can manage and use the multiple
devices like one single device. The IRF technology brings about the
following benefits:
1) Streamlined management
After an IRF is built, a user can log in to the unified logical device by
connecting to any port on any device, to manage the entire intelligent
resilient system and all member devices in the system by configuring
a single device, and it is not required to be physically connected each
member device to configure and manage the member devices.
2) Streamlined services
Various control protocols run in a logical device formed by using
the IRF also work as a single device. For example, routing protocols
perform unified computation as a single device. The cross-device link
aggregation technology is increasingly widely applied, and can replace
original Spanning Tree Protocols. This saves a large quantity of exchanges
between devices, streamlining network running, and reducing the
convergence time during network flapping.
3) Elastic expansion
Elastic expansion can be implemented as required, to protect user
investments. The IRF supports hot swapping of devices.
4) High reliability
The IRF is high reliably in terms of links, devices, and protocols. Physical
ports of member devices can be aggregated, and physical connections
between the IRF system and upper/lower-layer devices also support the
aggregation function. This improves link reliability by means of multi-link
backup. The IRF system consists of multiple member devices. If the
master device is faulty, the IRF system automatically elects a new master
device in a quick manner, to ensure service continuity of the IRF system,
thereby implementing 1:N backup of devices. The IRF system backups up
protocol configuration information to all other member devices in real
time by using the protocol hot backup function, thereby implementing
1:N protocol reliability.
5) High performance
For high-end switches, the improvements in performance and
port density are constrained by the hardware structure. The
performance and port density of the IRF system are equal to the
sum of performance and port densities of all member devices in the
IRF system. Therefore, by using the IRF technology, the switching
capacity and user port density of devices can be easily multiplied, to
significantly improve device performance.
· Complete Security Control Policies
The DH S5500 series switches support multiple authentication
functions. In a network environment with various clients, different
clients support different access authentication modes. For
example, some clients (for example, printer terminals) support
only MAC address authentication, some user host perform
802.1X authentication, and some user hosts expects only portal
authentication for web access. To flexibly meet the multiple
authentication requirements in this type of network environment, the
clients provide the Guest VLAN function. In this case, an authorized
access terminal is allowed to access only a specified resource
and use a corresponding policy, for example, obtaining an 802.1x
client, upgrading a client, or obtaining other upgrade programs.
The DH S5500 series switches support the Secure Shell V2 (SSH
V2) feature, which can provide secure information assurance and
powerful authentication functions, to protect the Ethernet switches
from attacks such as IP address spoofing and plaintext password
interception.
ARP attacks and ARP viruses are greatest threats to local area
network security. The DH S5500 series switches support a variety of
ARP defense functions, such as APR detection and ARP rate limiting.
The ARP detection function is used to check user legality and ARP
packet validity, and the ARP rating limiting function is used to protect
CPUs from being affected by a large quantity of ARP packets.
· Diversified QoS Policies
1) The DH S5500 series switches support the following QoS features:
Packet filtering on layer 2 (L2) to layer 4 (L4)
2) Flow classification based on the source MAC address, destination
MAC address, source IP address, destination IP address, TCP/UDP
port, IP protocol type, and VLAN
3) Flexible queue scheduling algorithms, including SP, WRR, and
SP+WRR, which can be configured based on both ports and queues
· High Availability
The DH S5500 provides device-level and link-level multi-level
reliability protection. The hardware supports the following protection
techniques:
1) Over-current protection, over-voltage protection, and over-heat
protection technologies
2) Fault detection and alarm reporting concerning the power source
and fans

3) Automatic adjustment of fan rotation speed according to temperature
changes
These design features ensure high reliability of the devices. In addition
to device-level reliability, the switches further support the following
link-level reliability features:
1) Diversified link-level reliability technologies, including protection
protocols such as LACP, STP, RSTP, MSTP, and PVST
2) IRF2
3) 1:N redundant backup
4) Ring stack
5) ross-device link aggregation
These features significantly improve network reliability, and the network
convergence time is not affected even if multiple services and a large
traffic are carried on the network, ensuring normal service operation.
· Environment Friendliness and Energy Saving
The DH S5500 series switches use pioneering energy-saving chips
and innovative architecture design. This achieves minimum power
consumption of the 1000M switches. In addition, "zero-noise"
silence design is implemented on some models, providing users with
leading-edge green network access products that achieve environment
friendliness and energy saving, thereby reducing maintenance costs for
users.
Multiple techniques are used on the DH S5500 series switches, to ensure
environment friendliness and energy saving. The techniques include:
1) Auto-power-down (automatic energy saving on ports): If a status of
an interface remains "down" for a specific period of time, the system
automatically stops supplying power to the interface, and the interface
automatically enters the power saving mode.
2) EEE energy saving function: If a port remains idle for a specific period
of time, the system enables the energy saving mode of the port. When
packets need to be transmitted or received, listening code streams sent
periodically are used to wake up the port to resume services, thereby
achieving an energy saving effect.
The DH S5500 series switches comply with the RoHS standards.
