LevelOne GTL-2891 Stackable L3 Managed Gigabit Switch

24x Gigabit2x 10G SFP+ + 10G slotFull L3 (OSPF)Stackable

The LevelOne GTL-2891 is a 28-port stackable Layer 3 managed Gigabit switch from the KILBY series, combining 24 Gigabit ports with two 10G SFP+ uplinks and an additional 10G module slot. With full Layer 3 routing including OSPF and the ability to stack multiple units as one, it is a capable, value-focused core or aggregation switch. Typically in stock with fast delivery across Cyprus.

Compatibility — check before buying:
This is a non-PoE switch - powered devices need a separate PoE injector or switch. The two 10G SFP+ uplinks and the 10G module slot need matching transceivers or a module (sold separately). It is a full Layer 3 switch (static, RIP and OSPF), distinct from the L3 Lite siblings in the range. Stacking lets several units be managed as one; it is rack-mountable.

Best For

✓ SMB and campus cores needing full Layer 3 (OSPF)
✓ Aggregation of access switches over 10G SFP+
✓ Deployments wanting a spare 10G module slot for expansion
✓ Stacked topologies managed as a single unit
✓ VLAN routing and multi-subnet networks
✓ Value-focused L3 switching with dynamic routing

Key Features

 
24 Gigabit + 2x 10G SFP+ + module slot
Twenty-four Gigabit ports plus two 10G SFP+ uplinks and an extra 10G module slot give flexible high-speed connectivity and room to expand.
 
Full Layer 3 routing
Static, RIP and OSPF dynamic routing lift it above L3 Lite switches, suiting real multi-subnet and campus-edge topologies.
 
Stackable management
Multiple GTL-2891 units can be stacked and managed as a single logical switch, simplifying administration and adding resilience.
 
Managed and rack-ready
VLANs, ACLs, QoS and LACP with web, CLI and SNMP management deliver a secure, well-controlled network in a rack-mount chassis.

Frequently Asked Questions

Does the GTL-2891 support OSPF?
Yes. It is a full Layer 3 switch supporting static, RIP and OSPF dynamic routing, plus inter-VLAN routing - distinct from the L3 Lite models in the LevelOne KILBY range.
Can it be stacked?
Yes. Multiple GTL-2891 units can be stacked and managed as a single logical switch, simplifying administration and improving resilience across the aggregation layer.
What is the 10G module slot for?
In addition to the two 10G SFP+ uplinks, a 10G module slot lets you add further high-speed connectivity as your network grows. The module is sold separately.
Does it have PoE?
No. The GTL-2891 is a non-PoE switch. To power access points, cameras or phones, use a separate PoE injector or a PoE switch.
Singular Expert Insight
The GTL-2891 is the full-L3 member of LevelOne's KILBY range: OSPF, stacking and a spare 10G module slot at a price well below the big enterprise vendors. It suits a value-conscious core or aggregation role where dynamic routing matters. If you only need L3 Lite, the GTL-2881 is cheaper; the GTL-2872 is a fibre-heavy variant. Browse our wider switch range or add PoE-powered access points alongside it (via a PoE switch or injector).

Buyer's Guide

Buy it if
You want affordable full Layer 3 (OSPF) with 24 Gigabit ports, 10G SFP+ uplinks, a spare 10G module slot and stacking, without needing PoE.
Skip it if
You need PoE, multi-gig ports, or only basic L3 Lite - a PoE, multi-gig or lower-tier switch may suit better.
Also consider
The L3 Lite GTL-2881 for a lower cost, or the fibre-oriented GTL-2872.
