Features

Layer 3 All-Optical 10G Core & Aggregation Switch
RG-S6120-20XS4VS2QXS

Recommended aggregation switch for large-sized networks, or core switch for small and medium-sized networks. With 20 x 10G SFP+ ports and 4 x 25G SFP28 ports, the switch provides flexible access capabilities. The 2 x 40G QSFP+ uplink ports deliver high-speed uplink connectivity, fully satisfying the requirements of high-performance networks.

VSU Virtualization, Flexible Networking and High Performance

Millisecond Failover

High Scalability

Simplified Networking

The VSU connects to peripherals through an aggregate link, realizing service switching in milliseconds upon a failure.

VSU virtualization technology is supported to increase bandwidth through link aggregation, which greatly improves forwarding capabilities of the switch.

Multiple physical switches can be virtualized into one logical unit to simplify network configuration and architecture, eliminating loops, and improving reliability.

Hardware Redundancy, Guaranteed Service Continuity
and Network Connectivity

Hot-Swappable Power Modules + Intelligent Fan Modules

Hardware-Level Boot Redundancy

Optical Port Fault Isolation

Power modules can be replaced without affecting device operation. Intelligent fan speed regulation is supported for efficient cooling,
providing dual protection for the network.

Two Flash chips are used to store the system boot program for hardware-level boot redundancy, avoiding device failure caused by a failed Flash chip.

The innovative isolated chip design ensures that short-circuit current cannot reach the power supply chip directly. Failure of one optical module will not affect the normal operation of other optical ports, thus effectively ensuring service stability.

Network Security Policies and Real-Time Monitoring, Delivering Enhanced Network Robustness

CPP

NFPP

CPP protects the CPU from data attacks to ensure CPU stability under high usage, achieving significant improvement in the device's security performance.

Abundant QoS Policies for Flexible Resource Allocation,
Making Congestion a Thing of the Past

With multi-plane flow classification and control capabilities for MAC flow, IP flow and application flow, accurate resource allocation for multi-service traffic makes congestion a thing of the past, delivering high-quality networks.

Managed by the INC Controller to Achieve Easy and Efficient O&M Management

The switch automatically completes registration and
configuration after it accesses the all-optical network, achieving
plug and play, no commissioning and fast onboarding.

A switch can be flexibly replaced based on service needs
without reconfiguration. Service ports supports auto-sensing,
achieving automatic O&M.
