The LevelOne XQS-3126 is a high-density 26-port Top-of-Rack (TOR) fiber switch designed for modern data centers, cloud platforms and enterprise server farms. With 24 x 1G/10G SFP+ ports and 2 x 40G/100G QSFP28 uplinks, it delivers flexible spine–leaf connectivity for high-performance servers, storage systems and aggregation switches.
Powered by high-performance ASICs and multi-core processors, the XQS-3126 provides up to 880Gbps of switching capacity with wire-speed L2/L3/L4 forwarding and low latency. It supports advanced features such as IPv4/IPv6 routing, QoS, traffic analysis and network virtualization to ensure predictable performance for mission-critical workloads, virtualization clusters and cloud applications.
For high availability, the switch integrates hot-swappable, redundant power supplies and fans, plus comprehensive redundancy protocols including STP/RSTP/MSTP, VRRP, ring protection, dual uplink and LACP link aggregation. In-service software upgrade (ISSU) and graceful restart (GR) help maintain continuous services during maintenance windows, while Virtual Switch System (VSS) and virtual stacking of up to 10 units simplify management with a single logical device view.
Whether deployed as a TOR switch in a leaf–spine fabric or as a high-capacity aggregation node, the XQS-3126 combines performance, resiliency and scalability to meet the demanding requirements of next-generation data centers.
