benefits can you get from the Huawei S5700-EI switches? In this article, we
will tell the detailed Features and Highlights of the S5700-EI, which can help
you know these Huawei switches well.
Powerful support for services
• The S5700-EI
supports IGMP v1/v2/v3 snooping, IGMP filter, IGMP fast leave, and IGMP proxy.
It supports line-speed replication of multicast packets between VLANs,
multicast load balancing among member interfaces of a trunk, and controllable
multicast, meeting requirements for IPTV services and other multicast services.
• The S5700-EI
provides the Multi-VPN-Instance CE (MCE) function to isolate users in different
VPNs on a device, ensuring data security and reducing costs.
• The S5710-EI
supports multiple MPLS & VPN features, including Label Distribution
Protocol (LDP) or Resource Reservation Protocol for Traffic Engineering
(RSVP-TE), MPLS TE, VLL, VPLS, and MPLS L3VPN.
Comprehensive
reliability mechanisms
• Besides STP,
RSTP, and MSTP, the S5700-EI supports enhanced Ethernet reliability
technologies such as Smart Link and RRPP (Rapid Ring Protection Protocol),
which implement millisecond-level protection switchover and ensure network
reliability. It also provides Smart Link multi-instance and RRPP multiinstance to
implement load balancing among links, optimizing bandwidth usage.
• The S5700-EI
supports enhanced trunk (E-Trunk) that enables a CE to be dual-homed to two PEs
(S5700s). E-Trunk greatly enhances link reliability between devices and
implements link aggregation between devices. This improves reliability of access
devices.
• The S5700-EI
supports the Smart Ethernet Protection (SEP) protocol, a ring network protocol
applied to the link layer on an Ethernet network. SEP can be used on open ring
networks and can be deployed on upper-layer aggregation devices to provide fast
switchover, ensuring non-stop transmission of services.
SEP features
simplicity, high reliability, fast switchover, easy maintenance, and flexible
topology, facilitating network planning and management.
• The S5700-EI
supports Ethernet Ring Protection Switching (ERPS), also referred to as G.8032.
As the latest ring network protocol, ERPS was developed based on traditional
Ethernet MAC and bridging functions and uses mature Ethernet OAM function and a
Ring Automatic Protection Switching (R-APS) mechanism to implement
millisecond-level protection switching. ERPS supports various services and
allows flexible networking, helping customers build a network with lower OPEX
and CAPEX.
• The S5700-EI
supports redundant power supplies, and can use an AC power supply and a DC
power simultaneously. Users can choose a single power supply or use two power
supplies to ensure device reliability.
• The S5700-EI
supports VRRP, and can set up VRRP groups with other Layer 3 switches. VRRP
provides redundant routes to ensure stable and reliable communication. Multiple
equal-cost routes to an uplink device can be configured on the S5700-EI to
provide route redundancy. When an active route is unreachable, traffic is
switched to a backup route.
• The S5700-EI
supports Bidirectional Fast Detection (BFD) and provides millisecond-level
detection for protocols such as OSPF, IS-IS, VRRP, and PIM to improve network
reliability. The S5700-EI complies with IEEE 802.3ah and 802.1ag. IEEE 802.3ah
defines the mechanism for detecting faults on direct links over the Ethernet in
the first mile, and 802.1ag defines the mechanism for end-to-end service fault
detection. The S5700-EI supports Y.1731. Besides fast end-to-end service fault
detection, the S5700-EI can use the performance measurement tools defined in
Y.1731 to monitor network performance, providing accurate data about network
quality.
Well-designed
QoS policies and security mechanisms
• The S5700-EI
implements complex traffic classification based on packet information such as
the 5-tuple, IP precedence, ToS, DSCP, IP protocol type, ICMP type, TCP/UDP
port number, VLAN ID, Ethernet protocol and CoS. ACLs can be applied to inbound
or outbound direction on an interface. The S5700-EI supports a flow-based
two-rate three-color CAR. Each port supports eight priority queues and multiple
queue scheduling algorithms such as WRR, DRR, PQ, WRR+PQ, and DRR+PQ. All of
these ensure the quality of voice, video, and data services.
• The S5700-EI
provides multiple security measures to defend against Denial of Service (DoS)
attacks, and attacks against networks or users. DoS attack types include SYN
Flood attacks, Land attacks, Smurf attacks, and ICMP Flood attacks. Attacks to
networks refer to STP BPDU/root attacks. Attacks to users include bogus DHCP
server attacks, man-in-the-middle attacks, IP/MAC spoofing attacks, DHCP
request flood attacks. DoS attacks that change the CHADDR field in DHCP packets
are also attacks against users.
• The S5700-EI
supports DHCP snooping, which generates user binding entries based on MAC
addresses, IP addresses, IP address leases, VLAN IDs, and access interfaces of
users. DHCP snooping discards invalid packets that do not match any binding
entries, such as ARP spoofing packets and IP spoofing packets. This prevents
man-in-the-middle attacks to campus networks that hackers initiate by using ARP
packets. The interface connected to a DHCP server can be configured as a
trusted interface to protect the system against bogus DHCP server attacks.
• The S5700-EI
supports strict ARP learning, which prevents ARP spoofing attacks that will
exhaust ARP entries. It also provides IP source check to prevent DoS attacks
caused by MAC address spoofing, IP address spoofing, and MAC/IP spoofing.
• The S5700-EI
supports centralized MAC address authentication, 802.1x authentication, and
NAC. It authenticates users based on statically or dynamically bound user
information such as the user name, IP address, MAC address, VLAN ID, access
interface, and flag indicating whether antivirus software is installed. VLANs,
QoS policies, and ACLs can be applied to users dynamically.
• The S5700-EI
can limit the number of MAC addresses learned on an interface to prevent
attackers from exhausting MAC address entries by using bogus source MAC
addresses. This function minimizes packet flooding that occurs when MAC
addresses of users cannot be found in the MAC address table.
Fine-grained
traffic management
• The S5710-EI supports NetStream. The NetStream module supports V5, V8, and V9 packet formats and
provides various traffic analysis functions, such as real-time traffic
sampling, dynamic report generation, traffic attribute analysis, and traffic
exception report. The Netstream module enables administrators to monitor
network status in real time and provides applications and analysis functions
including potential fault detection, effective fault rectification, fast
problem handling, and security monitoring, to help customers optimize network
structure and adjust resource deployment.
• The S5700-EI
supports the Sampled Flow (sFlow) function, which uses a sampling mechanism to
obtain statistics about traffic forwarded on a network and sends the statistics
to the Collector in real time. The Collector analyzes traffic statistics to
help customers manage network traffic efficiently. The S5700-EI integrates the
sFlow Agent module and uses hardware for traffic monitoring. Unlike traffic
monitoring through port mirroring, sFlow does not degrade network performance
during traffic monitoring.
Easy deployment
and maintenance free
• The S5700-EI
supports automatic configuration, plug-and-play, and batch remote upgrade.
These capabilities simplify device management and maintenance and reduce maintenance
costs. The S5700- EI supports SNMP v1/v2/v3 and provides flexible methods for
managing devices. Users can manage the S5700-EI using the CLI, Web NMS, Telnet,
and HGMP. The NQA function helps users with network planning and upgrades. In
addition, the S5700-EI supports NTP, SSH v2, HWTACACS+, RMON, log hosts, and
port-based traffic statistics.
• The S5700-EI
supports the GARP VLAN Registration Protocol (GVRP), which dynamically
distributes, registers, and propagates VLAN attributes to reduce manual
configuration workloads of network administrators and to ensure correct VLAN
configuration. In a complex network topology, GVRP simplifies VLAN
configuration and reduces network communication faults caused by incorrect VLAN
configuration.
• The S5700-EI supports
MUX VLAN. MUX VLAN isolates Layer 2 traffic between interfaces in a VLAN.
Interfaces in a subordinate separate VLAN can communicate with ports in the
principal VLAN but cannot communicate with each other. MUX VLAN is usually used
on an enterprise intranet to isolate user interfaces from each other but allow
them to communicate with server interfaces. This function prevents
communication between network devices connected to certain interfaces or
interface groups but allows the devices to communicate with the default
gateway.
PoE function
• The S5700-EI
PWR can use PoE power supplies with different power levels to provide -48V DC
power for powered devices (PDs) such as IP Phones, WLAN APs, and Bluetooth APs.
In its role as power sourcing equipment (PSE), the S5700-EI PWR complies with
IEEE 802.3af and 802.3at (PoE+) and can work with PDs that are incompatible
with 802.3af or 802.3at. Each port provides a maximum of 30 W power, complying
with IEEE 802.3at. The PoE+ function increases the maximum power of each port
and implements intelligent power management for high-power consumption
applications. This facilitates the use of PDs. PoE ports can work in
power-saving mode. The S5700-EI PWR provides improved PoE solutions. Users can
configure whether and when a PoE port supplies power.
High
scalability
• The S5700-EI
supports intelligent stacking (iStack). Multiple S5700-EI switches can be
connected with stack cables to set up a stack, which functions as a virtual
switch. A stack consists of a master switch, a backup switch, and several slave
switches.
The backup switch takes over services when the master switch fails,
reducing service interruption time. Stacks support intelligent upgrade so that
users do not need to change the software version of a switch when adding it to
a stack. The iStack function allows users to connect multiple switches with
stack cables to expand system capacity. These switches can be managed using a
single IP address, which greatly reduces the costs of system expansion,
operation, and maintenance. Compared with traditional networking technologies,
iStack has advantages in scalability, reliability, and system architecture.
Various IPv6
features
• The S5700-EI
supports IPv4/IPv6 dual stack and can migrate from an IPv4 network to an IPv6
network. S5700-EI hardware supports IPv4/IPv6 dual stack, IPv6 over IPv4
tunnels (including manual tunnels, 6to4 tunnels, and ISATAP tunnels), and Layer
3 line-speed forwarding.
The S5700-EI can be deployed on IPv4 networks, IPv6
networks, or networks that run both IPv4 and IPv6. This makes networking
flexible and enables a network to migrate from IPv4 to IPv6.
