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.

! Example Ansible task using OcNOS OpenConfig NETCONF module:
!
! - name: Configure VXLAN interface via OpenConfig NETCONF
!   netconf_config:
!     host: "{{ inventory_hostname }}"
!     username: admin
!     password: "{{ vault_password }}"
!     content: |
!       <config>
!         <interfaces xmlns="http://openconfig.net/yang/interfaces">
