## Long description

The LevelOne KILBY GTL-2881 is a managed, stackable L3 Lite Gigabit switch with 28 ports: 24 x 10/100/1000BASE-T RJ-45 ports, two 10G SFP+ fiber ports and one 10G expansion slot for a dual-port module. Designed for high-performance server aggregation and backbone upgrades, this rack-mountable switch supports advanced networking standards and delivers a switching capacity of 128 Gbit/s with a MAC address table of 16,000 entries for efficient traffic handling.
Advantages
The GTL-2881 provides high-density Gigabit connectivity with two 10GbE uplinks and an expansion slot for additional 10G ports, enabling flexible network growth. It supports a broad set of Layer 2 and Lite Layer 3 features (VLANs, QoS, link aggregation and basic L3 routing) and common IEEE standards for interoperability. The unit is rack-mountable, relatively lightweight at 3.7 kg, and offers centralized management suitable for enterprise edge or aggregation deployments.
Suitable for
 Enterprise data center server aggregation
 Backbone uplinks and aggregation switches
 Gigabit-to-the-desktop for power users and small workgroups
 Networks requiring VLANs, QoS and link aggregation
Key specifications
 Ports: 24 x 10/100/1000BASE-T RJ-45, 2 x 10G SFP+, 1 x 10G expansion slot
 Switching capacity: 128 Gbit/s
 MAC address table: 16,000 entries
 Managed switch with L3 Lite features
 Supported standards: IEEE 802.1Q, 802.3z, 802.3x, 802.3u, 802.3ad, 802.1x, 802.1w, 802.1s, 802.1p, 802.1D
 Color: Grey; Weight: 3.7 kg
How to use
Mount the switch in a standard 19-inch rack and connect power according to the installation guide. Use the RJ-45 ports for copper connections to desktops and servers and the SFP+ ports (or installed 10G expansion module) for fiber uplinks to aggregation or core switches. Configure management settings via the web GUI, CLI or supported management protocols to create VLANs, set QoS policies, and configure link aggregation and basic routing where required.
Usage recommendations
For optimal performance, use the 10G SFP+ ports or the 10G expansion module for uplinks to core switches, segment traffic with VLANs and apply QoS to prioritize latency-sensitive services. Keep firmware updated and monitor MAC table usage when connecting many endpoint devices.
