Overview

The OcNOS SP Layer 2 Guide provides a comprehensive reference for switching and Ethernet capabilities tailored for service provider network. It consolidates all Layer 2 protocols and features into a single resource, covering fundamental bridging, VLAN management, and advanced Carrier Ethernet features such as Provider Bridging (802.1ad) and L2 control protocol tunneling.

Each feature includes conceptual overviews, configuration procedures, topology examples, and command references. This guide explains how Layer 2 functions operate within OcNOS to ensure low latency in high-density data center architectures.

Target Users

This guide is intended for:

• Network administrators designing scalable Ethernet switching and backhaul architectures responsible.
• Operations teams deploying and maintaining Carrier Ethernet services in Service Provider networks.
• Support engineers troubleshooting protocol behavior, loop prevention, and Layer 2 forwarding issues.
• Technical evaluators assessing the Layer 2 switching capabilities of OcNOS for service provider deployments.

Key Capabilities

This guide enables users to:

• Configure and operate fundamental Layer 2 protocols including STP, RSTP, and MSTP.
• Manage VLANs and Private VLANs for secure traffic isolation and broadcast domain management.
• Deploy Carrier Ethernet services such as Provider Bridging (QinQ), including VLAN translation and registration tables.
• Implement Link Bundling using static and dynamic Link Aggregation Groups (LAG) and Multi-Chassis Link Aggregation (MLAG) for node-level redundancy.
• Tunnel Layer 2 Control Protocols (L2CP) through SP networks to support transparent customer control planes for protocols like STP and LACP.
• Enforce Network Access Control through IEEE 802.1X authentication, MAC Authentication Bypass (MAB), and Port Security features.
• Validate and troubleshoot Layer 2 traffic via Link Layer Discovery Protocol (LLDP) and traffic mirroring (SPAN/RSPAN).
