The series is also equipped with a complete lineup of L2 features, including IGMP snooping, port mirroring, Spanning Tree Protocol (STP), and Link Aggregation Control Protocol (LACP), as well as L3 lite Static Routing.
Along with market-leading FPGA functionality the L Series combines rich Layer 1+ network functions on the same device, to reduce complexity and cost, including signal regeneration, port mirroring and media conversion.
