OVERVIEW Features SPECIFICATIONS Ordering Information

Overview

The SF-M series cloud campus switches are access and aggregation products designed for next generation cloud campus network. They run with the enterprise-ready SONiC version (SeraNOS).

Based on Marvell Prestera switch ASIC, SF-M series switches provide large table entry size, wire-speed forwarding and low power consumption, and support comprehensive L2 and L3 functions, have rich security features. All 1 GE/2.5 GE hardware has a PoE version to provide 802.3at/802.3bt standard PoE functions.

Operating System Highlights

SeraNOS is an enterprise network operating system developed with SONiC and SAI as the kernel.

Integrated rich L2/L3 network features, complete support for network virtualization, QoS policies and other services.
Advanced functional containerized & event-driven system architecture to accelerate network service development/customization.
Provides an open Rest API interface that can be centrally managed and invoked by third-party applications such as cloud management platform.
Provides KLISH command line for traditional network engineers.

suitable SKUs to build a campus network from tens to hundreds of thousands access ports.

All layer-3 network can avoid some problems in traditional campus network like broadcast storm and ethernet loop.
Leaf switches have the same configuration, so one profile can be used to configure all the leaf switches with ZTP.
With distributed gateway deployed, wireless terminals can achieve lossless roaming by connecting a new gateway before disconnecting the former one.
Virtualization features like VXLAN, BGP EVPN are also migrated from data center, which can meet the growing requirements of campus network.

Cloud-based Campus Network

Sera is the first vendor that run SONiC in campus switches. Spine-leaf architecture is introduced into campus network, so that we just need a few also be left blank as pure Linux, customer can run applications they need, such as management

Optional DPU for Multipurpose

CX102S-16GT-M-SWP has an option to add at most 2×4-core DPU. Customer can choose to pre-install OpenWRT to play the role as a router or a firewall, or OpenWiFi controller to manage WLAN. It can tools or radius server.

Cloud Cluster as a Single Device

Click here to add your own text

Scale-out spine-leaf architecture to build a cloud cluster instead of traditional stacking features.
Compared with traditional stacking, there is no limitation of max stackable device number or proprietary stacking cable.
As an example, when DCS206P-48S as spine and DCS204Y-48GT as leaf, a POD can be built to provide 48 x 48=2304 access ports.
After simple peer configurations, the cloud cluster can be built and considered as a virtual device, other configurations can be synchronized automatically.
