SmartMC (Intelligent Management Center)
SmartMC enables centralized management of distributed access switches to cut O&M workload for small & mid-sized campus networks, split into four modules: intelligent configuration, device upgrade & fault maintenance, topology visualization and end-user access control. S5120V3-SI can be managed under SmartMC for easy unified maintenance.
Visualization Capability
Equipped with Telemetry over GRPC, the switch uploads real-time resource and alarm data to management platforms for network tracing, fault diagnosis, risk warning and architecture optimization.
Comprehensive Service Performance
It delivers high-density Gigabit access for broadband, VoIP and VOD multimedia services. Key features include 4K VLAN, 12K jumbo frame, 802.1X/MAC/port security, LACP, port isolation, ACL, port rate limiting, IPv6 and Ethernet OAM (802.3ah/802.1ag).
IRF2 (Intelligent Resilient Framework 2)
IRF2 virtualizes up to multiple switches into one logical unit via copper or fiber for long-distance stacking.
- Unified management: Configure the whole stack through any single device port.
- Simplified networking: Cross-device link aggregation replaces most spanning tree protocols to speed convergence.
- Hot-pluggable expansion: New switches join the stack without service interruption.
- 1:N redundancy: Automatic master switch failover and real-time protocol backup ensure non-stop forwarding.
- Scalable performance: Total switching capacity equals the sum of all stacked devices.
Complete Security Policies
Supports triple multi-authentication on single port for MAC/802.1X/Web Portal access to fit mixed terminal environments, plus Guest VLAN for restricted unauthorized access. SSHv2 defends against IP spoofing and plaintext interception. Built-in ARP Detection and ARP rate-limit block ARP attacks. Cooperated with iMC/EAD, it unifies endpoint antivirus, patch management and access control to realize proactive full-network security defense.
Rich QoS Functions
L2~L4 traffic classification based on MAC, IP, port and VLAN; SP/WRR/SP+WRR queue scheduling, bidirectional ACL, CAR policing, dual-direction port mirroring and sFlow sampling for traffic monitoring & troubleshooting.
Excellent Manageability
Supports SNMPv1/v2/v3, CLI, Telnet, SSH2.0 and Web management compatible with iMC & OpenView. MAC-based VLAN, global/VLAN-pushed ACL and BIMS zero-configuration deployment simplify mass network setup.
High Reliability
Hardware overcurrent/overvoltage/overheat protection plus adjustable smart fan and fault alarm. Supported link protocols: LACP/STP/RSTP/MSTP/Smart Link, IRF2 1:N backup, ring stacking and cross-device link aggregation. CPU protection filters malicious packets to guarantee stable operation under heavy load.
Professional Surge Protection
Built-in lightning protection supports 10KV surge withstand on service ports to avoid lightning damage under harsh field conditions.
Green Energy-saving Design
Adopts low-power chips, Auto-Power-Down for inactive ports and EEE idle-port power saving; fully compliant with EU RoHS standards to lower power consumption and operating cost.
