Compare Compare
The GTL-2091 is LevelOne latest generation of 20-Port L3 Managed Gigabit Switch, 8 x Gigabit RJ45, with 12 10G SFP+ port connectivity. High-density SFP ports built into allow users to insert different SFP transceivers providing the necessary fiber connections for creating  Area Networks infrastructure. also offers AC dual power failover, allowing for continued operation regardless of a single power source failure.
The GTL-2091 offers powerful L3 features(IPv4/v6 static route, RIP v1/v2, OSPF v2/v3, BGP, PIM-DM, PIM-SM ), The switch also supports the most advanced IPv6 management,IPv6 security, and IPv6 multicast control in accordance with the growth of IPv6 deployment. ISPs can expand their services for home to business users by providing a more reliable and resilient network , and advanced OAM (Operations, Administration, and Maintenance) functions to ensure service-level agreements. enabling you to scale your operations to meet business growth, operational cost savings, and ease of management.
