Features

Layer 3 GE Core & Aggregation Switch RG-CS85-48GT4XS-HPD

Aggregation switch for small and medium-sized campus networks, with four 10G uplink optical ports for data transmission; 48 x 10/100/1000BASE-T ports, PoE/PoE+ supported, providing high-speed network experience for short-distance services. Core switch for small and medium-sized enterprise networks, with high scalability, efficiency, and manageability, and device-level and link-level reliabilities for stable connectivity.

Hardware Redundancy, Guaranteed Service Continuity and Network Connectivity

Hardware-level Boot Redundancy

Hot-Swappable Power Modules

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.

VSU Virtualization, Flexible Networking and High Reliability

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.

Layer 3 Routing Control, Adaptive to Multiple Services, Efficient and Guaranteed Data Transmission

Static and Dynamic Routing

IPv4 and IPv6 Protocols

Abundant Multicast Protocols

In simple campus scenarios, the switch can achieve easy configuration and high information security, while in large-scale interconnecting scenarios, the switch can realize auto-negotiated update of transmission paths to improve transmission quality.

The hardware supports dual stack for high-speed switching, catering to the requirements of campus network transition from IPv4 protocol to IPv6 protocol, with significant improvement in address table capacity and network security.

Point-to-multipoint directional communication can avoid data redundancy on the network, realizing safe and efficient data transmission.

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

CPP

NFPP

Large amounts of data from different sources are handled by CPP first to prevent direct attacks on the CPU, ensuring CPU stability under high usage, and achieving significant improvement in the device's security performance.
