Cheap 8 ports RJ45 Huawei S5700-10P-PWR-LI-AC Optical Fiber Switch

Various Combination of Ports

The S5700-EI, S5710–EI and S5720-EI support various extended subcards that provide highdensity
GE/10GE uplink ports. The flexible port combinations meet bandwidth expansion requirements, protecting customers' investment.

Intelligent Stack

The S5700 supports intelligent stack (iStack). This technology combines multiple switches into a logical switch.
Member switches in a stack implement redundancy backup to improve device reliability and use
inter-device link aggregation to improve link reliability. iStack provides high network scalability. You can increase ports, bandwidth, and processing capacity of a stack by simply adding member switches to the stack. iStack also simplifies device configuration and management. After a stack is set up, multiple physical switches are virtualized into one logical device. You can log in to any member switch in the stack to manage all the member switches in the stack.

Comprehensive VPN Technologies

The S5700 supports the multi-VPN-instance CE (MCE) function, which allows users in different VPNs to connect to the same switch and isolates users through multi-instance routing. Users in multiple VPNs connect to a PE device through the same physical uplink port on the switch,which reduces the investment on network deployment. The S5710-EI and S5700-HI support Multiprotocol Label Switching (MPLS) QoS, MPLS traffic engineering (TE), virtual leased line(VLL), virtual private LAN service (VPLS), and Layer 3 virtual private network (L3VPN). They can provide high-quality private line access services for enterprises and are cost-effective caseshaped MPLS switches.

Easy Operation and Maintenance

The S5700 supports EasyDeploy, USB-based deployment, batch remote upgrade and is a plugand-
play product. These functions facilitate device deployment, upgrade, service provisioning,and other management and maintenance operations, and also greatly reduce costs of operation and maintenance. The S5700 can be managed and maintained using Simple Network

Management Protocol (SNMP) V1, V2c, and V3, command line interface (CLI), web-based network management system, Telnet, or Secure Shell (SSH) V2.0. Additionally, it supports remote network monitoring (RMON), multiple log hosts, port traffic statistics collection, and network quality analysis that help in network consolidation and reconstruction.
The S5700 can use the GARP VLAN Registration Protocol (GVRP) to implement dynamic
distribution, registration, and propagation of VLAN attributes. GVRP reduces manual configuration workload and ensures correct configuration. Besides, the S5700 supports the MUX VLAN function, which involves a principal VLAN and multiple subordinate VLANs.
Subordinate VLANs are classified into group VLANs and separate VLANs. Ports in the principal
VLAN can communicate with ports in subordinate VLANs. Ports in a subordinate group VLAN can communicate with each other, whereas ports in a subordinate separate VLAN can communicate only with ports in the principal VLAN.

Flexible Ethernet Networking

In addition to traditional Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP),and Multiple Spanning Tree Protocol (MSTP), the S5700 supports Huawei-developed Smart Ethernet Protection (SEP) technology and the latest Ethernet Ring Protection Switching (ERPS) standard. SEP is a ring protection protocol specific to the Ethernet link layer, and applies to various ring network topologies, such as open ring topology, closed ring topology, and cascading ring topology. This protocol is reliable, easy to maintain, and implements fast protection switching within 50 ms. ERPS is defined in ITU-T G.8032. It implements millisecond-level protection switching based on traditional Ethernet MAC and bridging functions.
The S5700 supports Smart Link and Virtual Router Redundancy Protocol (VRRP), which implement backup of uplinks. One S5700 switch can connect to multiple aggregation switches through multiple links, significantly improving reliability of access devices. In addition, the S5700 provides multiple connection fault detection mechanisms, including Ethernet OAM(IEEE 802.3ah/802.1ag /ITU Y.1731) and Bidirectional Forwarding Detection (BFD). The S5700HI provides hardware-based 3.3 ms Ethernet OAM and 10 ms BFD.

Diversified Security Control

The S5700 supports MAC address authentication and 802.1X authentication and implements
dynamic delivery of policies (VLAN, QoS, and ACL) to users.
The S5700 provides a series of mechanisms to defend against DoS attacks and user-targeted
attacks. DoS attacks are targeted at switches and include SYN flood, Land, Smurf, and ICMP

flood attacks. User-targeted attacks include bogus DHCP server attacks, IP/MAC address spoofing, DHCP request flood, and change of the DHCP CHADDR value. The S5700 collects and maintains information about access users, such as IP addresses, MAC addresses, IP address leases, VLAN IDs, and access interfaces in a DHCP snooping binding table. In this way, it can defend against DHCP attacks on the network. You can specify DHCP snooping trusted and untrusted ports to ensure that users connect only to the authorized DHCP server.
The S5700 supports strict ARP learning. This feature prevents ARP spoofing attackers from
exhausting ARP entries so that users can connect to the Internet normally.

Mature IPv6 Technologies

The S5700 uses the mature, stable Versatile Routing Platform (VRP) and supports IPv4/IPv6 dual stacks, IPv6 routing protocols (RIPng, OSPFv3, BGP4+, and IS-IS for IPv6), and IPv6 over IPv4 tunnels including manual, 6-to-4, and Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) tunnels. With these IPv6 features, the S5700 can be deployed on a pure IPv4 network,a pure IPv6 network, or a shared IPv4/IPv6 network, helping realize IPv4-to-IPv6 transition.

Innovative built-in battery
The S5700-LI-BAT(S5700-28P-LI-BAT and S5700-28P-LI-24S-BAT) is the industry's first switch model that supports internal lithium batteries as a backup power supply. It ensures uninterrupted services in situations where power failures frequently occur at the access layer.
The S5700-LI-BAT has the following advantages:
•    In the event of a mains power failure the battery can power the switch, so services will not be interrupted.
•    Compared with switches using external power supply units, the S5700-LI-BAT occupies less space and is easier to install.
•    Intelligent power management, long standby time.
•    Battery LAN switches on the entire network can be managed centrally using a web system,
facilitating network operation and maintenance. As the battery lifetime is predictable, you do not need to replace batteries periodically, reducing hardware costs.
•    The internal battery provides alarm and voltage/current protection functions as well as
overtemperature protection, which enhance reliability.

CSFP providing high-density access and increased bandwidth

CSFP switches support downlink CSFP ports. Each downlink CSFP port equipped with a CSFP
GE optical module and one pair of fibers can provide 2 Gbit/s bandwidth bidirectionally, which is two times the bandwidth of standard SFP optical modules. The 24 downlink CSFP ports can provide 48 Gbit/s bandwidth bidirectionally, implementing high-density access (equal to access of 48 standard SFP ports) and saving the cost of deploying fibers and adding optical modules.
