High Availability & Virtual Stacking
VSU enables up to 9 switches to act as one logical switch, with seamless failover (50–200ms). ERPS, RLDP, and STP variants enhance availability.
Energy Efficiency & Silent Workflows
Energy Efficient Ethernet (802.3az), low standby consumption, and fanless design reduce power and noise, ideal for large-scale deployment.
Dual Power & Rugged Design
Supports both AC and HVDC inputs with protection up to 6kV for reliable operation in industrial or utility environments.
Deployment Scenarios
Campus Access in Quiet Zones
Ideal for classrooms, libraries, or conference areas—silent operation with gigabit access and 10G uplinks via stacking SFP modules.
Healthcare & Broadcast Networks
Fanless, compact design enables deployment near sensitive equipment or in noise-critical environments.
Smart Building & IoT Edge
With high port density and power reliability, this access network switch supports IP cameras, sensors, and building automation edge aggregation.
Small Data Center Aggregator
Layer‑2/3 routing, link aggregation, and stacking allow it to serve in smaller DC environments.
Enterprise Branch Office Core
Supports edge routing, VLAN separation, and redundancy, making it suitable for remote branch network cores.
Deployment & Management Experience
- Zero-Touch Stacking: VSU enables rapid multi-switch setup without manual reconfiguration.
- Central Orchestration: Manage via Ruijie Cloud or SNMPv3/RMON, with CLI, web, Telnet, and SSH.
- Silent, Efficient Operation: Fans-free build minimizes noise and cooling demands.
- High Resilience: Dual power design and robust switching protocols ensure reliability.
CLI Configuration Examples for RG‑S2928G‑E
Enable Web Management Service
User community reports confirm the need to manually enable the web interface:
Ruijie# configure terminal
Ruijie(config)# enable service web-server
Ruijie(config)# enable service https-server # optional secure web
Ruijie(config)# exit
Ruijie# show service
Create VLAN and Assign Ports
Based on RGOS configuration guide snippets:
Ruijie# configure terminal
Ruijie(config)# vlan 10
Ruijie(config)# vlan 20
Ruijie(config)# interface vlan 10
Ruijie(config-if-Vlan10)# ip address 192.168.10.1 255.255.255.0
Ruijie(config-if-Vlan10)# exit
Configure a Trunk Port with Native VLAN
Standard syntax from manual:
Ruijie(config)# interface gigabitEthernet0/1
Ruijie(config-if-GigabitEthernet0/1)# switchport mode trunk
Ruijie(config-if-GigabitEthernet0/1)# switchport trunk native vlan 10
Ruijie(config-if-GigabitEthernet0/1)# switchport trunk allow-pass vlan 10 20
Set Up Stacking (VSU)
User guide indicates VSU must be configured via CLI:
Ruijie# configure terminal
Ruijie(config)# vsu enable
Ruijie(config)# vsu domain 1
Ruijie(config)# exit
# Connect stacking cables then reload peer units—units become 1 logical switch
Ruijie# show vsu status
Enable SSH Management Access
Method follows RG‑S2900G-E series guide:
Ruijie# configure terminal
Ruijie(config)# enable service ssh-server
Ruijie(config)# crypto key generate rsa size 1024
Ruijie(config)# username admin password <yourpassword>
