Model Number.
GTL-2091
SKU
57082203
  • High-Density 10G Ports: 12 x 10-Gigabit SFP+ slots and 8 x Gigabit RJ45 ports provide flexible fiber and copper aggregation for core and distribution layers
  • Redundant Power Design: Dual AC power inputs ensure continuous operation and higher availability in case of a single power source failure
  • Advanced Layer 3 Routing: Supports IPv4/IPv6 static routes, RIP v1/v2, OSPF v2/v3 and BGP for scalable multi-segment network deployment
  • Stacking & Scalability: Virtual stacking of up to 4 switches into one logical device for unified management, monitoring and configuration
  • Security & Access Control: Access Control Lists (ACL) and RADIUS authentication help protect the network edge and core from unauthorized access
  • VLAN & Segmentation: Supports tag-based VLAN and Q-in-Q tunneling to isolate traffic and build secure multi-tenant or service-provider environments
  • Resilient L2 Topology: IEEE 802.1d/w/s Spanning Tree Protocol (STP/RSTP/MSTP) and port mirroring enhance redundancy and simplify troubleshooting
  • Multicast & IPTV Ready: IGMP Snooping v1/v2/v3, MLD and PIM-DM/PIM-SM provide efficient multicast delivery for video, IPTV and streaming services
  • Traffic Protection: Unknown unicast, broadcast and multicast storm control prevent traffic storms from impacting network performance
  • QoS & Bandwidth Control: QoS based on IP DSCP enables advanced traffic prioritization and bandwidth management for critical applications
  • IPv6-Ready Platform: Full IPv4/IPv6 dual-stack support with advanced IPv6 management, security and multicast control
  • Comprehensive Management: DHCP client/server, OAM, Telnet, SNMP v1/v2c/v3, RMON, web browser and TFTP management for flexible monitoring and configuration
  • The LevelOne GTL-2091 is a high-density 20-port L3 managed 10G aggregation switch, designed for carrier, campus and enterprise core networks. It combines 12 x 10G SFP+ fiber ports with 8 x Gigabit RJ45 ports, delivering flexible copper and fiber connectivity for data centers, server farms and metro/area network backbones. With dual AC power inputs, the GTL-2091 provides power redundancy so the switch continues operating even if one power source fails.

    Featuring comprehensive Layer 3 routing functions including IPv4/IPv6 static routing, RIP v1/v2, OSPF v2/v3 and BGP, the GTL-2091 supports complex multi-segment networks and dynamic route convergence. Advanced IPv6 management, security and multicast control (PIM-DM/PIM-SM, IGMP Snooping, MLD) make it ready for next-generation ISP and enterprise deployments. Rich L2 features such as VLAN (tag-based, Q-in-Q), STP/RSTP/MSTP, storm control and ACL/RADIUS access control help build secure and resilient topologies.

    The GTL-2091 supports virtual stacking of up to 4 units into a single logical switch, simplifying centralized management, configuration and monitoring. QoS based on IP DSCP ensures critical services such as voice, video and business-critical applications receive priority bandwidth. With extensive OAM, SNMP, RMON, web and CLI management options, the GTL-2091 delivers carrier-grade visibility while keeping daily operation efficient and cost-effective.
