The CX732Q-M-H is a 1U core switch built on the Marvell Falcon ASIC. It packs 32 ports of 400GbE QSFP-DD and 2 ports of 10GbE SFP+ into a single 3.2 Tbps switching fabric, with a forwarding rate of 2.8 Bpps and 24MB of packet buffer. That combination is meant for the spine/core tier of leaf-spine (CLOS) fabrics, AI/ML clusters, and hyperscale data center networks — the layer that has to absorb east-west traffic from multiple leaf switches without becoming the choke point.
It ships preloaded with AsterNOS, Asteraix's Enterprise SONiC-based network operating system. That gets you a full Layer 2/Layer 3 feature set — VXLAN, BGP-EVPN, OSPFv2/v3, MLAG, ECMP — alongside automation interfaces (ZTP, RESTful APIs, NETCONF/YANG, gNMI) designed to plug into existing infrastructure-as-code pipelines rather than forcing a new management workflow on your team.
For high-availability requirements, AsterNOS adds EVPN multihoming for all-active server redundancy without dedicated peer links, and optional MPLS support for label-switched path management across complex topologies. An optional network packet broker container — built on SONiC's containerized architecture — adds traffic mirroring, filtering, aggregation, and load balancing without a separate appliance.
Timing-sensitive deployments can add the optional PTP extension card, supporting IEEE 1588v2 and SMPTE 2059-2 with PTP Class C accuracy (≤10ns maximum time error) — relevant for use cases like financial trading infrastructure or broadcast networks where clock synchronization is non-negotiable.

Advanced Hardware Features
Engineered for scalability, efficiency, and always-on reliability.
400/10G High-Speed Ports Enable Flexible Network Scaling
Boasting 32×400GbE QSFP-DD and 2×10GbE SFP+ ports, the device supports interface splitting via breakout cables, which helps enhance the efficiency of network resource usage and accommodate diverse application scenarios.
The dual 1+1 hot-pluggable power supplies ensure continuous operation by allowing replacement without system shutdown. Equipped with 3+1 hot-pluggable fan modules, the system delivers reliable cooling performance to maintain stability and efficiency under demanding workloads.
Optional MPLS Module
Enhance Your Network with Advanced MPLS Capabilities
This switch model supports robust MPLS functionality, enabling efficient label-switched path management and seamless traffic forwarding across complex networks. It delivers active-active-like reliability through MPLS-based redundancy mechanisms, ensuring uninterrupted connectivity for mission-critical applications.
Power Your Network with EVPN Multihoming
Our switches deliver standards-based EVPN Multihoming, enabling all-active server redundancy without peer links. Experience enhanced reliability, optimized load balancing, and simplified management across multi-vendor environments.
Feature Set
This model supports full network virtualization features:
GRE/static GRE tunnels for point-to-point overlays, plus VXLAN with BGP-EVPN for scalable L2/L3 virtualization across distributed environments.Perfect for flexible, multi-tenant campus/enterprise networks.
The switch integrates sFlow and Telemetry for continuous, high-frequency KPI export, and uses ZTP to cut deployment time and human intervention. Its open management interface supports RESTful APIs, NetConf/YANG, and gNMI, enabling programmable remote configuration/monitoring and seamless integration with automation platforms and IaC toolchains.
Advanced Routing Capabilities
Equipped with powerful routing capabilities, including static routing, VRF, OSPFv2/v3, BGP, and MP-BGP, this model ensures flexible network segmentation and dynamic route management for demanding enterprise and campus environments.
Enterprise SONiC Asteraix’s Switches with PTP Support
Our switch fully supports IEEE1588 PTPv2 and SMPTE 2059-2 standards both through hardware and software. The hardware port supports PTP as a Boundary Clock (BC) or Transparent Clock (TC), with customizable modules to fit customer needs. On the software side, Asteraix leads the way in implementing and optimizing PTP in SONiC, delivering top performance on our AsterNOS Enterprise Distribution. Currently, it supports PTP Class C with a maximum time error of ≤10 ns.
Network Packet Broker Functionality
The SONiC-based campus switches CX-M series take full advantage of SONiC’s open and containerized architecture, and fully leverage its capabilities by installing the new APP-PB container and deploying packet broker docker functionality on SONiC.
This integration unlocks a range of advanced features, including traffic mirroring, raw data tagging, filtering, aggregation, preprocessing, load balancing, and output replication.
