OcNOS 6.5 for Data Centers: OpenConfig Automation, EVPN Scale, and 400G Spine

OcNOS 6.5 for Data Centers is now generally available. This release is the automation milestone — OpenConfig YANG model support via NETCONF means DC operators can manage OcNOS switches using the same automation frameworks they use for other OpenConfig-capable devices. Combined with new 400G spine platform support and EVPN-VXLAN scale improvements, OcNOS 6.5 DC delivers a mature, production-ready disaggregated fabric platform.

OpenConfig YANG Model via NETCONF

OcNOS 6.5 DC supports server-side NETCONF with OpenConfig YANG data models for interfaces, BGP, and network instances. This is the key capability that enables OcNOS to integrate into Ansible, Terraform, and custom automation frameworks that already use OpenConfig for multi-vendor network management.

New 400G Spine Platform: Edgecore AS9516-32D

OcNOS 6.5 DC introduces support for the Edgecore AS9516-32D — a 32×400G QSFP-DD spine switch on Broadcom Tomahawk 3, delivering 12.8 Tbps of switching capacity for large-scale DC fabric deployments. This platform enables operators to migrate from 100G spine to 400G without changing NOS.

EVPN-VXLAN Scale and Stability

OcNOS 6.5 DC improves EVPN-VXLAN scale limits across supported platforms:
