The CX204P-4Y48MT-M-H is a 1U enterprise access switch
that delivers 48× 2.5GbE RJ45 ports plus 4× 100G QSFP28 (40G compatible) and 4× 25G SFP28 (10G compatible) uplinks for 800 Gbps of switching capacity. Built on the Marvell Prestera 98DX4570 (AlleyCat 5P) ASIC and running Enterprise SONiC (AsterNOS), it is designed as an access-layer switch for enterprise and campus networks, aggregating end-devices, IP phones, access points, and IoT endpoints onto a 100G/25G distribution tier.
With 256K IPv4 routes, 128K IPv6 routes, and 128K MAC entries, the CX204P-4Y48MT-M-H matches the routing and endpoint scale of a small-to-mid-size access deployment. Its 48 × 2.5GbE ports give each access point, IP phone, camera, and IoT endpoint 2.5 times the bandwidth of a standard gigabit port over existing Cat5e/Cat6 cabling. The uplink ports connect directly to a leaf/spine or aggregation layer without an intermediate speed-conversion step, and can be run at 40G and 10G respectively where the upstream infrastructure requires it. With EVPN overlay support, access-layer segments can be extended across the campus network.
Enterprise SONiC, full L2/L3 and open management
The switch ships preloaded with AsterNOS, Enterprise SONiC distribution, on the same single software image used across the CX-M family. On top of it sits a complete Layer 2/Layer 3 feature set — VLANs, static routing, OSPF, BGP, MLAG, and IPv6 — for access-layer segmentation and routing. Industry-standard CLI and SNMP v1/v2/v3 keep the switch consistent with existing operations workflows, without a separate management path for a small-port-count device.
High availability with MC-LAG
MC-LAG support gives the CX204P-4Y48MT-M-H active-active redundancy across dual-homed links, maintaining connectivity through a link or device failure. Combined with BFD-based link fault detection, the switch re-routes traffic across OSPF and BGP in under 50ms.
PoE+/PoE++ power delivery
Ports 1–8 support PoE++ (802.3bt) and ports 9–48 support PoE+ (802.3at, 30W/port). The switch auto-detects connected devices and supplies the appropriate power without manual configuration. It is available in 740W, or 1440W total power budget variants, sized to the mix of IP phones, Wi-Fi 6/Wi-Fi 7 access points, and surveillance cameras on the network.
Optional precision timing
The CX204P-4Y48MT-M-H is available in PTP and non-PTP variants. The PTP variant supports IEEE 1588v2 PTP, with the hardware port operating as a Boundary Clock (BC) or Transparent Clock (TC), for access deployments where downstream devices also need a synchronized time reference.
Operations and traffic visibility
The switch integrates sFlow, port mirroring and Syslog for traffic visibility and troubleshooting, with ZTP reducing deployment time and manual intervention.
Centralized management with Asteria Network Controller
The Asteria Network Controller can manage the CX204P-4Y48MT-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 CX204P-4Y48MT-M-H uses hot-swappable 1+1 redundant power supplies and 2+1 redundant, hot-swappable fans for power and cooling redundancy. Front-to-rear airflow suits rack-mount campus and enterprise access deployments.
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.
