  • Ports: 24 x Gigabit Ethernet ports, 2 x Gigabit SFP/RJ45 combo ports, 2 x 10G SFP+ uplinks, 1 x 10G expansion slot
  • Stacking: Supports 8-unit physical stacking and up to 36-unit virtual stacking
  • Layer features: L3 Lite static routing plus full L2 support including VLAN, QoS and STP
  • Aggregation: IEEE 802.3ad LACP for bandwidth expansion
  • Resilience: ERPS ring protection enabling sub-50 ms failover
  • Security: Dynamic ARP Inspection (DAI) for ARP spoofing mitigation
  • Multicast: IGMP Snooping for efficient video and streaming traffic
  • Diagnostics: Supports OAM for monitoring and troubleshooting
  • IPv4/IPv6: Dual-stack support for modern enterprise environments
  • The LevelOne GTL-2882 KILBY is a high-performance 28-port Stackable L3 Lite Managed Gigabit Fiber Optic Switch designed for enterprise networks requiring powerful uplinks, enhanced fiber connectivity and scalable centralized management. It features 24 Gigabit RJ45 ports, 2 Gigabit SFP/RJ45 combo ports, 2 dedicated 10G SFP+ uplink ports and a 10G expansion slot for additional dual-port modules.

    With a comprehensive suite of L2 capabilities—including VLAN, QoS, STP, LACP and IGMP Snooping—the GTL-2882 provides robust traffic segmentation, bandwidth control and multicast optimization. L3 Lite features such as static routing further improve network performance and help reduce reliance on core routers. Security is enhanced through Dynamic ARP Inspection (DAI), protecting the network against spoofing attacks.

    The GTL-2882 supports stacking of up to 8 physical units and virtual stacking of up to 36 switches for unified management, monitoring and configuration, simplifying administration across enterprise campuses and multi-floor network architectures. Combined with OAM diagnostics, ERPS ring protection with sub-50ms failover and energy-efficient IEEE 802.3az technology, the switch delivers performance, resilience and scalability for modern enterprise networking environments.
