16x25Gb SFP28, 4x100Gb QSFP28 L3 Aggregation/Leaf Switch,  Enterprise SONiC Ready, MLAG VXLAN

The Asterfusion CX204P-16Y-M-E is a 16×25G aggregation switch with 4×100G QSFP28 uplinks, built for campus aggregation, spine applications, enterprise networks, and cloud service provider deployments. Powered by the Marvell Aldrin 3 chipset in a compact 1RU form factor, it delivers high throughput, port density, and efficiency in a sleek design.
Running on AsterNOS, the commercial SONiC-based NOS, this Layer 3 switch offers a comprehensive feature set—from industry-standard routing protocols like OSPF and BGP to advanced capabilities including VXLAN, BGP-EVPN, MLAG, and IPv6. Optional PTP and MPLS support further enable low-latency, time-sensitive, and high-performance workloads.
In modern network architectures, the CX204P-16Y-M-E typically serves as a distribution/aggregation switch, but in small to mid-sized networks, it can also function as a cost-effective Top-of-Rack (ToR)/Leaf switch, providing a versatile solution for private clouds or compact data centers.
