The GTL-2891 are a family of high-performance Gigabit Ethernet Layer 3 switches featuring 28 ports; with 24 10/100/1000BASE-T ports, 2 10G SFP+ ports, and one 10G dual port expansion slot. The switches are ideal for high-performance server aggregations, such as enterprise data centers, where they can connect high-end or network-attached files servers over fiber ports. They can also be deployed as a backbone upgrade, or to provide Gigabit–to-the-desktop for power users. These switches are packed with features and are a cost-effective solution that bring continuous availability, enhanced security, and advanced QoS to the network edge, while maintaining simplicity of management.\n\n- Dynamic ARP Inspection (DAI) protects switches against ARP spoofing\n- Supports up to 8 switches in one stack\n- Supports Operations, Administration, and Maintenance (OAM) mechanisms\n- Ethernet Ring Protection Switching (ERPS) for Ethernet ring topologies with sub-50 ms failover capabilities\n- IEEE 802.1d/w Spanning Tree Protocol (STP) and port mirroring\n- IEEE 802.3ad LACP for auto port aggregation\n- Supports port-based VLAN, IEEE 802.1Q VLAN Tagging\n- QoS control for traffic prioritization and bandwidth management
