- Dynamic ARP Inspection (DAI) protects switches against ARP spoofing - Stacking up to 8 switches in one stack - Support Operations, Administration, and Maintenance (OAM) mechanisms - Ethernet Ring Protection Switching (ERPS) for Ethernet ring topologies with sub-50 ms failover capabilities - IEEE 802.1d/w Spanning Tree Protocol (STP) and port mirroring - IEEE 802.3ad LACP for auto port aggregation - Supports port-based VLAN, IEEE 802.1Q VLAN Tagging - QoS control for traffic prioritization and bandwidth management The GTL-2881 series includes high-performance Gigabit Ethernet Layer3 Lite switches featuring 28 ports; 24 10/100/1000BASE-T ports, two 10G SFP+ ports, and one 10G expansion slot for a dual-port module. The switch is ideal for high-performance server aggregations, such as enterprise data centers, where it can connect high-end or network-attached file servers through fiber ports. It can also deployed as a backbone upgrade, or to provide Gigabit-to-the-desktop for power users. This switch is packed with features and is a cost-effective solution that brings continuous availability, enhanced security, and advanced QoS to the network edge, while maintaining simplicity of management.
