High Performance

The RG-S5750E Series offers 10 Gigabit Ethernet ports to ensure smooth traffic flowing, even at 10 times the normal network speed. The series meets the needs of fast growing network applications and increasing network bandwidth. 

Offers upgradable 10 Gigabit Ethernet ports to meet current and future demands. 

IPv4/IPv6 Multilayer Switching

Provides hardware support for IPv4/IPv6 multilayer switching at line rates, supports distinction and processing of IPv4 and IPv6 packets by hardware, and provides flexible IPv6 network communication schemes according to requirement planning and network status of the IPv6 network.

Supports rich IPv4 routing protocols, including static routing protocols, RIP, OSPF, and BGP4, which enable users to select appropriate protocols for network building in different environments.

Supports rich IPv6 routing protocols, including static routing protocols, RIPng, OSPFv3, and BGP4+, which enable users to select appropriate protocols for upgrading an existing network to an IPv6 network or building a new IPv6 network.

Network Virtualization Support

Up to 8 switches can be virtualized into one logical unit. 

Switches operation management can be unified and simplified through single IP address, Telnet and CLI session.  

Enables any Virtual Switch Unit (VSU) member to leave or join the VSU group with zero business interruption, offering high reliability and availability.

Provides high degree of flexibility; can be realized with either Gigabit Ethernet or 10 Gigabit Ethernet ports without limitation on copper or fiber media types. 

Aggregates up to 8 Gigabit Ethernet ports or 4 10 Gigabit Ethernet ports as the VSU Link.

Flexible and Comprehensive Security Policies

Effectively prevents and controls virus spread and hack attacks with various inherent mechanisms, such as anti-DoS attacks, hacker IP scanning, illegal ARP packets checking and multiple hardware ACL policies.

Supports hardware-based IPv6 ACL. Allows coexistence of IPv4/IPv6 users and controls the resources access by IPv6 users.

Industry-leading CPU protection mechanism: The CPU protection policy (CPP) distinguishes the data flows sent to the CPU, which are processed according to their priorities, and implements the limitation on the bandwidth rate as needed. In this manner, users can prevent the CPU from being occupied by illegal traffic and protect against malicious attacks to guarantee normal operation of the CPU and switch.

Implements flexible binding of a port or the system to the IP address and MAC address of users, strictly limiting user access on a port or in the entire system.

Supports DHCP snooping, and allows DHCP responses from trusted ports only. Based on DHCP listening and by monitoring ARP dynamically and checking the user IP address, the series directly discards illegal packets inconsistent with binding entries to effectively prevent ARP frauds and source IP address frauds.

Telnet access control based on the source IP address to prevent illegal personnel or hack attacks and strengthen the device security.

Secure Shell (SSH) and Simple Network Management Protocol v3 (SNMPv3) cryptographic network protocol ensure the security of management information and provide services such as multi-element binding, port security, time-based ACL and bandwidth rate limiting to block unauthorized users.

Superior Multiservice Support Features

Supports IPv4 and IPv6 multicast functions, including rich multicast protocols such as IGMP Snooping, IGMP, MLD, PIM, PIM for IPv6, and MSDP, to provide multicast service support for IPv4 networks, IPv6 networks, and IPv4/IPv6 dual-stack networks. Supports the Internet Group Management Protocol (IGMP) source IP address checking to guard against illegal multicast sources and improve network security.

Supports rich Layer 3 service features such as Equal-cost Multipath routing (ECMP) and Weighted-cost Multipath routing (WCMP) to meet communication needs of different link planning.

Supports IPFIX (RFC 3917) traffic analysis protocol, providing in-depth network flow information for operation management and troubleshooting support.

Advanced QoS Policies

Supports multilayer traffic classification and flow control capabilities such as MAC traffic, IP traffic, and application traffic that implement multiple traffic policies such as refined bandwidth control and forwarding priorities; supports the provision of services according to the corresponding QoS level. 

The QoS guarantee system with DiffServ at its core supports complete QoS policies such as 802.1p, IP TOS, Layers 2 through 7 filter, SP, and WRR.

High Reliability

Supports Spanning Tree Protocols (STP) of 802.1d, 802.1w, and 802.1s to ensure rapid convergence, improve fault tolerance capabilities, ensure stable running of networks and load balancing of links, and provide redundant links.

Supports the Virtual Router Redundant Protocol (VRRP) to effectively ensure network stability.

Supports Rapid Link Detection Protocol (RLDP) to detect the connectivity of links and whether an optical fiber link is normal from both ends, and supports the loop detection function based on the port to prevent network faults caused by loops generated by the connection of devices such as hubs to ports.

Supports Rapid Ethernet Ring Protection Protocol (RERP), a Layer 2 redundancy protocol designed for the core Ethernet. Its loop blocking and link recovery are performed on the master device, and a non-master device reports its link status to the master device without processing by other non-master devices. Therefore, the loop blocking time and link recovery time are shorter than those in the case of STP. Based on the preceding differences, the link recovery capability of RERP can reach a 100-subsecond level in an ideal environment.

When Spanning Tree Protocol (STP) is disabled, the Rapid Ethernet Uplink Protection Protocol (REUP) can provide basic link redundancy through the rapid uplink protection function and provide faster millisecond-level fault recovery than STP.

Supports Bidirectional Forwarding Detection (BFD) to provide a method for upper-layer protocols such as routing protocols and MPLS to rapidly detect the connectivity of forwarding paths between routing devices, reducing the convergence time of upper-layer protocols greatly in the case of changes in link status.

Ease of Use and Management

Various types of Gigabit Ethernet interfaces meet different network requirements. 

The RG-S5750-24GT/8SFP-P and RG-S5750-48GT/4SFP-P switches support PoE, which can provide power through remote PoE devices. The switches meet the network requirements of financial institutions, enterprises, schools, hospitals, and factories for implementing network applications such as VoIP, remote monitoring, and wireless APs.

Network Timing Protocol (NTP) provides an accurate and consistent timestamp for traffic information analysis and fault diagnosis.

Supports Syslog for effective network maintenance and management.

Supports port mirroring to ease the maintenance workload. 

The CLI interface provides convenience for advanced users.
