OcNOS training doesn't just teach the CLI — it builds deep protocol knowledge you can apply across any open networking environment.
Hands-On Lab Format
Every video walks through a real configuration task on live OcNOS hardware or VM. No slides, no theory — you see every CLI command and its output.
Competitive Edge
OcNOS expertise sets you apart in the open networking job market. As operators move away from proprietary vertically integrated solutions, demand for OcNOS skills is growing.
Operational Efficiency
Training on OcNOS before deployment reduces configuration errors and accelerates onboarding. Engineers who complete the course deploy faster and troubleshoot with confidence.
SP-Grade Protocol Depth
Covers the full carrier networking stack: IGPs, BGP, MPLS, EVPN, Segment Routing, and QoS — protocols used in real Tier 1 and Tier 2 service provider networks.
CLI Familiarity for Cisco & Juniper Engineers
OcNOS CLI is intentionally familiar to Cisco IOS and Junos engineers. The course highlights differences and shortcuts so experienced network engineers ramp up quickly.
Certificate of Completion
The professional course awards a recognized certificate, validating your OcNOS knowledge across L2, L3, MPLS, VPN, Segment Routing, and QoS domains.
