The Asterfusion CX532P-N-V2 is a 1RU data center switch
that delivers 32× 100G QSFP28 ports plus 2× 10G SFP+ for 3.2 Tbps of non-blocking, wire-speed Layer 2 and Layer 3 forwarding. Built on the Marvell Prestera Falcon ASIC and running the open, SONiC-based AsterNOS, it works equally well as a spine in 25G/100G spine-leaf fabrics or as a high-density 100G leaf for bandwidth-intensive compute and storage — designed for data center scenarios where east-west capacity, not extreme latency, drives the design.
With 128K MAC entries, 288K IPv4 routes and 4096 VLANs, the CX532P-N-V2 scales cleanly from a single pod to a large multi-tenant fabric. Every 100G port breaks out to 4×25G or 4×10G, so one switch can aggregate large numbers of 10G/25G servers or interconnect leaf and spine layers with flexible topology choices.
Open NOS, full L2/L3 and a consistent operating experience
The switch runs AsterNOS, Asterfusion's enterprise distribution of open-source SONiC, with a single software binary spanning the entire CX-N-V2 family — no per-feature license tiers, no vendor lock-in. On top of it sits a complete Layer 2/Layer 3 feature set: VXLAN, EVPN Type 1–5, distributed/anycast gateway, VRF and MC-LAG for multi-tenant overlays, plus full BGP, OSPF v2/v3, IS-IS, ECMP and policy-based routing for the underlay. Operators get a consistent management experience across every box — industry-standard CLI, REST API, NETCONF, Zero-Touch Provisioning and Syslog — so the same automation and tooling carry from one switch to the whole fabric.
High-precision time synchronization
Timing is a first-class capability on the CX532P-N-V2. The switch provides IEEE 1588v2 PTP with Class C accuracy and supports the full range of industry timing profiles — G.8275.1, G.8275.2, SMPTE 2059-2 and AES67 — across flexible clock roles including GrandMaster (GM), Boundary Clock (BC) and Ordinary Clock (OC). Combined with SyncE for physical-layer frequency distribution, it delivers the deterministic, low-jitter timing that AVoIP, broadcast, financial and industrial time-sensitive networks depend on.
Comprehensive multicast and RoCEv2 transport
For one-to-many media and data distribution, the switch offers a complete multicast toolset — IGMP v1/v2/v3, IGMP Snooping, IGMP Querier, PIM-SM and multicast routing — to keep AVoIP and broadcast traffic efficient and loss-free across large fabrics. For storage and AI/ML workloads, it adds RoCEv2 with PFC, PFC Watchdog, ECN, DCBX, Fast CNP and one-step Easy RoCE configuration, so a lossless RDMA fabric can be brought up in a single command.
Built-in observability
The CX532P-N-V2 is designed to be transparent in production. A native AsterNOS Prometheus exporter streams real-time switch metrics to your monitoring stack and renders them on ready-made Grafana dashboards, while sFlow, SPAN/ERSPAN and SNMP v1/v2/v3 provide flow sampling, traffic mirroring and standards-based management. Together they give operators per-port, real-time visibility for fast troubleshooting and capacity planning.
Carrier-grade reliability
Built for always-on data centers, the switch uses hot-swappable 1+1 redundant power supplies and 4+1 (N+1) redundant, hot-swappable fans to eliminate single points of failure. Flexible AC, DC and HVDC input options and selectable front-to-rear or rear-to-front airflow let it fit cleanly into hot/cold-aisle containment and mixed power environments — making the CX532P-N-V2 a dependable open-networking foundation for cloud data centers, HPC, distributed storage and AVoIP deployments.
