• 4× Gigabit SFP ports

Enjoy dependable gigabit connections for a wide range of devices, supporting high‑speed data transfer across your network.

Centralized Cloud Management with Omada SDN

The Omada SDN platform integrates network devices—including access points, switches, and gateways—into a single, centrally managed system.

• 100% centralized cloud management
• Highly scalable architecture
• Unified control from one interface

This solution delivers seamless wired and wireless connectivity, ideal for use in hospitality, education, retail, offices, and more.

Advanced L2+ and L3 Features

An extensive set of L2+ and L3 functions helps you build a scalable, robust, and efficient network, suitable for enterprises, campuses, and ISPs.

Key capabilities include:

• L2/L3/L4 QoS
• ACL (Access Control Lists)
• Static Routing

Static routing enables simple network segmentation and routes internal traffic directly through the switch for improved efficiency.

Enterprise‑Level Layer 2+ Capabilities

Support for comprehensive L2+ features provides flexible, reliable switching control:

• 802.1Q VLAN
• Port Mirroring
• STP/RSTP/MSTP
• Link Aggregation Control Protocol
• 802.3x Flow Control
• Advanced IGMP Snooping
• IGMP Throttling & Filtering

Multicast traffic is intelligently forwarded only to appropriate subscribers, reducing unnecessary traffic and preventing unauthorized multicast access at the port level.

Secure Networking

Protect your network with a rich set of security strategies designed to defend against a wide range of threats:

• IP‑MAC‑Port‑VID Binding
• Port Security
• Storm Control
• DHCP Snooping

An integrated list of common DoS attacks simplifies prevention and mitigation.

Access Control Lists (ACL, L2 to L4) restrict access to sensitive resources by filtering packets based on:

• Source and destination MAC address
• IP address
• TCP/UDP ports
• VLAN ID

User access can be controlled via 802.1X authentication, working with a RADIUS/Tacacs+ server to grant access only with valid user credentials.

Advanced QoS for Voice and Video

Prioritize critical applications to keep services running smoothly, even under limited bandwidth:

• Prioritization by IP address
• Prioritization by MAC address
• Prioritization by TCP/UDP port number

With Quality of Service (QoS), voice and video traffic maintain high quality and stability.

ISP‑Focused Features

Developed with service providers in mind, the switch includes ISP‑oriented functions such as:

• QinQ
• L2PT
• PPPoE ID Insertion
• IGMP Authentication
• Device Link Detection Protocol (DLDP) for easy link monitoring and troubleshooting

IPv6‑Ready for Next‑Generation Networks

Be prepared for evolving network requirements with comprehensive IPv6 support:

• Dual IPv4/IPv6 Stack
• MLD Snooping
• IPv6 ACL
• DHCPv6 Snooping
• IPv6 Interface
• Path Maximum Transmission Unit (PMTU) Discovery
• IPv6 Neighbor Discover

These IPv6 functions ensure your network is ready for the Next Generation Network (NGN) without requiring hardware upgrades.

Key Highlights

• 48× Gigabit RJ45 ports and 4× Gigabit SFP ports for reliable gigabit connectivity
• Full integration with Omada SDN for centralized cloud management
• Advanced L2+/L3 features for scalable, robust network design
• Comprehensive security with ACL, 802.1X, and anti‑DoS strategies
• Enterprise‑level capabilities for organizations, campuses, and ISPs
• QoS prioritization for smooth voice and video services
• ISP‑oriented tools and full IPv6 support for long‑term investment protection
