Product information

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.
