The CX308P-48Y-M-H is a 1U enterprise core switch
that delivers 48× 25G SFP28 downlink ports plus 8× 100G QSFP28 uplinks for 2.0 Tbps of switching capacity, with a forwarding rate of 2.6 Bpps and 24MB of packet buffer for non-blocking core-layer performance. Built on the Marvell Prestera Falcon ASIC and running Enterprise SONiC (AsterNOS), it is purpose-built for enterprise campus backbones and cloud service provider networks, connecting to core routers and higher-tier aggregation layers through its 100G uplinks while its 25G downlinks support dense server farms or access switches.
With 504K IPv4 routes, 252K IPv6 routes and 32K MAC entries, the CX308P-48Y-M-H anchors networks that scale from a handful of racks to large multi-tier deployments. Every 100G uplink 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-H family. On top of it sits a complete Layer 2/Layer 3 feature set — VXLAN, BGP-EVPN, GRE/static GRE tunnels, static routing, VRF, OSPFv2/v3, BGP, MP-BGP and MLAG — for multi-tenant overlays and dynamic route management at the network core. Automation interfaces include ZTP, RESTful APIs, NETCONF/YANG and gNMI, so the switch plugs into existing infrastructure-as-code pipelines without a separate management workflow.
High availability at the core
AsterNOS adds EVPN Multihoming for all-active redundancy to downstream switches without dedicated peer links, improving load balancing and simplifying multi-vendor deployments at the aggregation boundary. An optional MPLS module extends the switch with label-switched path management and MPLS-based redundancy for topologies where the core must stay reachable through multiple failure scenarios.
Optional precision timing
Timing-sensitive deployments can add the optional PTP extension card. The hardware port supports PTP as a Boundary Clock (BC) or Transparent Clock (TC), with IEEE 1588v2 and SMPTE 2059-2 support and PTP Class C accuracy (≤10ns maximum time error) — relevant where the core switch also needs to distribute a common clock reference, such as financial infrastructure or broadcast networks.
Operations and traffic visibility
The switch integrates sFlow and Telemetry for continuous KPI export, with ZTP cutting deployment time and manual intervention across the core layer. 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 — useful for monitoring traffic that converges at the core.
Centralized management with Asteria Network Controller
The CX308P-48Y-M-H is managed by the Asteria Network Controller, Asterfusion's unified platform for the CX-M switch family alongside APs, routers, and PON sticks. 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 CX308P-48Y-M-H uses hot-swappable 1+1 redundant power supplies and 3+1 (N+1) redundant, hot-swappable fans to eliminate single points of failure. Front-to-rear / Rear-to-front airflow and 100–240V AC / 36-72V DC input suit rack-mount campus deployments — making the CX308P-48Y-M-H a dependable foundation for campus, enterprise and data center core networks.
