The CX202P-16S-M-H is a 1U enterprise aggregation switch
that delivers 16× 10G SFP+ ports plus 2× 100G QSFP28 (40G QSFP+ compatible) uplinks for 1.09 Tbps of switching capacity, with a forwarding rate of 600 Mpps and 10MB of packet buffer. Built on the Marvell ArmStrongLP ASIC and running Enterprise SONiC (AsterNOS), it is designed for distribution and aggregation-layer roles in campus, enterprise and cloud service provider networks. With 62K IPv4 routes, 32K IPv6 routes, and 128K MAC entries, the CX202P-16S-M-H handles the routing and virtualization load of mid-sized networks. Its 100G uplink ports support interface splitting via breakout cables; each 100G port breaks out to 4×25G or 4×10G, so a single switch can fan out to a large number of downlink connections with flexible topology choices.
Enterprise SONiC, full L2/L3 and open management
The switch ships preloaded with AsterNOS, Enterprise SONiC distribution, with a single software image across the CX-M family. On top of it sits a complete Layer 2/Layer 3 feature set — VXLAN Centralized/Distributed Gateway, BGP-EVPN Type 2/3/5, GRE, static routing, VRF, OSPFv2/v3, BGP, MP-BGP, policy-based routing and MC-LAG — for multi-tenant overlays and dynamic route management at the aggregation layer. Automation interfaces include ZTP, industry-standard CLI, SNMP v1/v2/v3 and containerized custom tools, so the switch plugs into existing operations workflows without a separate management path.
High availability with MC-LAG
MC-LAG support gives the CX202P-16S-M-H active-active redundancy across dual-homed links, maintaining connectivity through a link or device failure without added protocol complexity. Combined with BFD-based link fault detection, the switch re-routes traffic across OSPF, BGP and IS-IS in under 50ms, keeping downtime minimal during unplanned outages. An optional MPLS module adds label-switched path management for topologies requiring MPLS-based redundancy.
Optional precision timing
The CX202P-16S-M-H supports IEEE 1588v2 PTP and SMPTE 2059-2 through hardware and software, with the hardware port operating as a Boundary Clock (BC) or Transparent Clock (TC). An optional PTP module adds Class C accuracy (≤10ns maximum time error) for deployments where the aggregation layer also needs to carry a synchronized time reference.
Operations and traffic visibility
The switch integrates sFlow, port mirroring and Syslog for traffic visibility and troubleshooting, with ZTP cutting deployment time and manual intervention. An optional Network Packet Broker container, built on SONiC's containerized architecture, adds traffic mirroring, filtering, aggregation, preprocessing, load balancing and output replication without a separate appliance.
Centralized management with Asteria Network Controller
The Asteria Network Controller can manage the CX202P-16S-M-H alongside other CX-M switches, APs, routers, and PON sticks in the same deployment. Zero-Touch Provisioning brings new switches online without manual CLI configuration. The controller provides topology discovery, device status monitoring, and scripted configuration or firmware updates across multiple switches from a single interface. On-premises deployment is available with no licensing fee.
Enterprise-grade reliability
The CX202P-16S-M-H uses hot-swappable 1+1 redundant power supplies and 2+1 redundant, hot-swappable fans to eliminate single points of failure. Front-to-rear airflow and 100–240V AC / 36-72V DC input suit rack-mount campus and enterprise deployments — making the CX202P-16S-M-H a dependable foundation for distribution and aggregation-layer networks.
Optimized Software for Advanced Workloads-AsterNOS
AsterNOS is the pre-installed network operating system on Asteraix’s CX-M Series campus switches. Built on SONiC and enhanced beyond the open-source version, AsterNOS offers advanced Layer 2 and Layer 3 features, as well as sophisticated routing capabilities. Support VXLAN EVPN virtualization, it supports scalable campus networks. AsterNOS is smart, secure, and easy to manage, providing a reliable operating platform for always-on enterprise networks.
