The LevelOne GTL-2091 is a high-performance 20-port L3 managed Gigabit and 10G aggregation switch designed for enterprise, campus and service provider networks. It combines 8 Gigabit RJ45 access ports with 12 high-density 10G SFP+ uplinks, enabling flexible fiber connectivity for building resilient core, distribution or metro Ethernet infrastructure.
With dual hot-swappable AC power inputs, the GTL-2091 provides power redundancy for continuous operation even if a single power source fails. This makes it ideal for mission-critical environments that demand high availability and non-stop services.
The switch delivers comprehensive Layer 3 routing, including IPv4/IPv6 static routing, RIP v1/v2, OSPF v2/v3, BGP and multicast routing (PIM-DM/PIM-SM). It also supports advanced IPv6 management, IPv6 security and IPv6 multicast control, allowing ISPs and enterprises to confidently deploy next-generation IP services while meeting stringent SLAs.
Virtual stacking of up to 4 switches lets administrators manage multiple GTL-2091 units as a single logical device, simplifying configuration and monitoring. Rich enterprise features such as VLAN (tag-based, Q-in-Q), ACL, RADIUS, QoS with IP DSCP, IGMP Snooping, MLD, storm control and powerful management interfaces (Web, CLI, Telnet, SNMP, RMON, TFTP) provide full control over traffic, security and performance from access to core.
