Product information

Description

The LEVELONE KILBY 28-Port L3 Lite Managed Switch (GTL-2872) is a Gigabit Ethernet access switch with four 10GbE SFP+ uplink ports and four combo Gigabit SFP/RJ45 ports. Designed for ISPs, MSOs, SMBs, enterprises and campus networks, the switch delivers Gigabit access with L3-lite features, a 128 Gbit/s switching capacity and a 16,000-entry MAC address table. It supports multiple IEEE standards for reliable layer‑2 and layer‑3 operation and is rack-mountable for deployment in wiring closets and data rooms.

Advantages

The GTL-2872 provides high availability and carrier-class resiliency with support for ITU-T G.8032 ERPS and advanced OAM functions to help meet service-level agreements. It offers comprehensive security features and IPv6 management, security and multicast controls to match growing IPv6 deployments. Hardware capabilities such as 10GbE uplinks, robust multicast control and advanced QoS enable efficient delivery of triple-play services and business applications while keeping management simple for administrators.

Suitable for

  • ISPs and MSOs delivering triple-play services to residential subscribers
  • SMB networks requiring Gigabit access and basic L3 features
  • Enterprise edge and campus distribution layers
  • Rack-mounted network rooms and wiring closets

  • Model: LEVELONE GTL-2872 (KILBY 28-Port L3 Lite)
  • Uplink: 4 x 10GbE SFP+
  • Access ports: 4 x Gigabit SFP/RJ45 combo
  • Switching capacity: 128 Gbit/s
  • MAC address table: 16,000 entries
  • Managed switch (L3 Lite)
  • Supported standards: IEEE 802.3ah, 802.3z, 802.3x, 802.3ae, 802.3ad, 802.1w, 802.1s, 802.1ag, 802.1D
  • Product colour: Black
  • Weight: 2.82 kg

How to use

Install the GTL-2872 in a standard 19-inch rack and connect uplink SFP+ modules to aggregation or core switches. Configure VLANs, QoS, multicast and IPv6 settings through the management interface to match your network design. Use the switch's ERPS and OAM features to create resilient rings and monitor service quality for subscriber and business links. Apply security policies and port configurations before placing ports into production.

Usage recommendations

For ISP deployments, enable ERPS and advanced OAM to improve resilience and SLA monitoring. Use 10GbE uplinks for aggregation to reduce bottlenecks, and plan VLANs and IPv6 address spaces in advance to simplify management. Regularly update firmware and backup configuration files to maintain security and availability.
