The switch achieves centralized authentication of wired and wireless networks on the core device via the built-in/external 802.1X/Portal authentication system. It can eliminate all the differences between access layer device performance and access mode. The RG-N18000 supports ≥170K ARP capacity, concurrent ≥90K IPv4/IPv6 dual stack devices with centralized authentication and authentication speed of 1200 devices per second. The web noise reduction feature can prevent illegal authentication packets to protect users’ Internet authentication experience. With Ruijie SAM, the RG-N18000 can also achieve refined management such as traffic billing and traffic control.
Moreover, RG-N18000 can further achieve network simplicity through the consolidation of SAN Storage Network into a unified Ethernet-based Storage Network via FCoE support.
Feature highlights supported by the respective sub-solution are illustrated in the figure below and described in the following sections.
N18000 Series Handles Both Networks with Ease
Ruijie RG-N18000 Series can act as the core of unified authentication and gateway of the campus network to offer simplified network experience for users. As the centralized authentication gateway, the core device can achieve unified assignment of security policies. The access layer and aggregation layer is only responsible for Layer 2 forwarding. As the device maintenance is simpler, the performance capacity is no longer a bottleneck. The core layer device provides rich features, high performance and high reliability. The centralized management of network management policies facilitates security monitoring, network expansion and new service development. The Ruijie RG-N18000 Series supports multiple authentication modes such as Portal/ 802.1X. MAC. Different management modes and technologies will be deployed in different scenarios according to different user requirements of the campus network so as to provide targeted and high-availability technologies and solutions.

Summary of Data Center Features Supported by N18000
Virtual Switch Unit 3.0 (VSU)
The series supports the Virtual Switch Unit 3.0 (VSU). The technology can virtualize multiple physical devices into one logical unit, which largely minimizes the number of network nodes and reduce administrator workload. Superior 50~200ms link failover ensures smooth and uninterrupted transmission of key services. The RG-N18000 Series supports cross-device link aggregation for easy double uplink to server/switch. The network can effectively maximize bandwidth investment return.
Benefits of 4-to-1 Virtualization
Virtual Switch Device (VSD)
Ruijie RG-N18000 Series delivers industry’s first 1:12 virtualization. One device can be virtualized into multiple virtual units. Hence, every virtual unit has a unique configuration management interface, independent hardware allocation (e.g. storage, TCAM and hardware forwarding table). All the features support restart with no effects on other virtual machines. Users can realize network resources allocation based on different needs. Resources of the core switch can hence be shared with other domains and users.
Benefits of 1-to-12 Virtualization
Transparent Interconnection of Lots of Links (TRILL)
Ruijie RG-N18000 Series supports Transparent Interconnection of Lots of Links (TRILL) of the IETF standard, allowing deployment of super large Layer 2 network in the data center. The feature enhances deployment flexibility and expands VM migration area. Ruijie data center products, ranging from access to core, all support the TRILL technology. It can simplify the network design and boost network scalability and flexibility, building a firm foundation for a large-scale virtualized cloud-computing network construction in the future.
Layer 2 Generic Routing Encapsulation (L2-GRE)
With the international L2-GRE standard, the RG-N18000 switches break the geographical boundaries to achieve data center L2 communication. Data center resources at different locations can be centrally managed and allocated.
Virtual Ethernet Port Aggregator (VEPA)
The Ruijie RG-N18000 Series supports Virtual Ethernet Port Aggregator (VEPA) of the IEEE802.1qbg standard. Data traffic from the server VM can be diverted to the physical network devices for “hard-switching”. This completely eliminates problems such as uncontrollable monitoring of VM traffic, incapability of unified policy deployment and server resources occupation caused by traditional “soft-switching”. All the features together optimize the next-gen data center network solution to fit into the virtual computing environment.
Virtual Machine Perception and Policy Auto-migration
The VM perception and automatic migration of policies features enable centralized deployment of VM traffic security policy in a large-scale server virtualization environment. Married with data center network management platform, data center switches, and VM management platform, it realizes simultaneous policy migration as virtual host can migrate smoothly within the network. It totally gets rid of security loopholes and hence lessens network maintenance workload.
Unified Switching with Integrated Storage and Ethernet
Ruijie RG-N18000 Series supports access via Fibre Channel over Ethernet (FCoE) or Ethernet for easy integration of heterogeneous storage and data networks. It greatly reduces the number of network devices.
The RG-N18000 switches and 10GE data center ToR device RG-S6220 together form a FC/FCoE data center integration solution. It can centrally manage FC SAN, IP SAN, FCoE SAN and IP network. It simplifies network deployment and minimizes cabling cost, hence totally protecting user’s investment.
