Cost-effective 10 GE Copper Port

The RG-S6220 switches provide 10 GE access through a high-density 10 GE Base-T port. The port supports the IEEE 802.3an standard and offers a 10 GE access bandwidth using the general RJ-45 twisted pair. The easy deployment of twisted pair keeps the original cabling of the data center in place with no disruption. It is also much more cost-effective than optical fiber. The RG-S6220 switches greatly minimize the construction costs of data centers.

IPv4/IPv6 Dual-Stack Multi-Layer Switching

The hardware of the RG-S6220 switches supports line-rate IPv4/IPv6 dual-stack multi-layer switching, and distinguishes and processes IPv4 and IPv6 protocol packets. The RG-S6220 switches also support multiple tunneling technologies including manually configured tunnels, automatic tunnels, ISATAP tunnels and so on. The switches provide flexible IPv6 inter-network communication solutions to be realized according the requirement plan and status quo of the IPv6 networks. The RG-S6220 switches are also applicable to an IPv4-only or IPv6-only network, or a hybrid of IPv4 and IPv6 network, fulfilling the transition requirements from IPv4 to IPv6 network.

The RG-S6220 switches support a wide range of IPv4 routing protocols including static routing, RIP, OSPF, and BGP4, which can be selected flexibly according to the network environment.

The RG-S6220 switches also support an abundant list of IPv6 routing protocols, such as static routing, RIPng, OSPFv3, and BGP4+, which can be selected flexibly either to upgrade the existing network to IPv6 network or to construct a new IPv6 network.

Carrier-Class Reliability Protection

The RG-S6220 switches support built-in redundant power modules and modularized fan components. All the interface boards, power modules, and fan modules are hot-pluggable to guarantee undisturbed switching operation. In addition, the RG-S6220 switches support fault detection and automatic alarms for the power and fan modules. The rotation speed of the fans automatically adjusts to the ambient temperature. The RG-S6220 switches further provide device-level and link-level reliability protection with the over-current, over-voltage, and overheating protection measures.

The RG-S6220 switches support an extensive family of link reliability technologies including Ruijie’s industry-leading Rapid Ethernet Ring Protection (RERP) and Rapid Ethernet Uplink Protection (REUP) mechanisms. The RG-S6220 switches also feature Graceful Restart (GR) and Bidirectional Forwarding (BFD) mechanisms. All the measures ensure the network convergence time is unaffected even when the network bears abundant services and heavy traffic, and therefore ensure normal operation.

Flexible and Comprehensive Security Policies

The RG-S6220 switches feature multiple security measures, which effectively defend against and control virus flooding and hacker attacks. These measures include anti-DoS attack, anti-IP scanning, validity check of ARP packets on ports, and multiple hardware-based ACL policies.

The RG-S6220 switches support hardware-based IPv6 ACLs, which can easily control IPv6 users' access to edge devices even when IPv6 users exist within an IPv4 network. It allows coexistence of IPv4 and IPv6 users on the network and can control access permissions of IPv6 users, such as restricting access to sensitive resources on the network.

The RG-S6220 switches adopt Ruijie’s industry-leading CPU Protection Policy (CPP) technology, which is an advanced hardware-based CPU protection mechanism, to distinguish data traffic destined to the CPU and process data according to queue priorities. The RG-S6220 switches implement bandwidth control to protect the CPU against unauthorized traffic consumption, malicious attacks and resource consumption and hence to ensure switch security. The hardware of the RG-S6220 switches allows flexible binding of a user IP address or a MAC address to a port or a switch to strictly control user access. The RG-S6220 switches support DHCP snooping, which allows only a DHCP response to a trusted port to prevent spoofing by unauthorized DHCP servers. Based on DHCP snooping, the RG-S6220 switches dynamically monitor ARP packets, check user IP addresses, and directly discard packets that do not comply with the bound entries. The RG-S6220 switches effectively defend against ARP spoofing and source IP address spoofing.

The RG-S6220 switches support Telnet access control based on source IP addresses. The measure prevents unauthorized users or hackers from attacking or controlling devices and thereby enhances security of the device NMS. The RG-S6220 switches also implement Secure Shell (SSH) and SNMPv3 to encrypt management information in Telnet and SNMP processes, thereby ensuring security of management device information and preventing hacker from waging attacks or controlling devices.

The RG-S6220 switches prevent unauthorized users from network access through multiple functions. These functions include multi-element binding, port security, time ACL, and bandwidth limit based on data traffic. The RG-S6220 switches highly strengthen access security and are perfect match for large-sized networks.
