Advanced Functions at an Affordable Price
The switch includes high-end switching and security features typically found in more costly switches, with comprehensive management options, advanced bandwidth control, and QoS for VoIP and other real-time applications.

Efficient Bandwidth Aggregation
Provide increased bandwidth for specific applications or segments by combining ports with 802.3ad LACP. Bundled ports create a multilink trunk for load balancing, with support for up to 14 groups and 8 ports per group.

Quality of Service Excellence
The switch supports advanced QoS with prioritization, classification, scheduling, and rate-limiting, featuring eight hardware queues for differentiated data management.

Security and VLAN Support
MAC address filtering and VLAN functionality provide robust network security and network segmentation capabilities.

Versatile Management
Monitor, configure, and control the switch via its RS-232 serial port or with CLI or web-based management over Ethernet.

Eco-Friendly
The SFP Gigabit/10-Gigabit Managed Fiber Switch Eco uses IEEE 802.3az Energy-Efficient Ethernet, reducing power consumption by up to 50% during low data activity.
