- IPv4 and IPv6 unicast and multicast routing.
- VRF (Virtual Routing and Forwarding) for network segmentation.
- ECMP (Equal-Cost Multi-Path) routing for efficient traffic load balancing.
- VXLAN: Supports Virtual Extensible LAN (VXLAN) for network virtualization and large-scale Layer 2 bridging.
- 5. Quality of Service (QoS)
- Traffic Classification: Based on Layer 2, Layer 3, and Layer 4 headers.
- Congestion Management: Advanced congestion management features like Data Center TCP (DCTCP).
- Priority Queuing: 8 priority queues per port for QoS.
- Traffic Shaping and Policing: Supports shaping, policing, and classification.
- 6. Security Features
- Access Control Lists (ACLs): Standard and extended ACLs for packet filtering and security.
- Port Security: Limits MAC addresses per port and restricts unauthorized devices.
- Storm Control: Protects against broadcast, multicast, and unknown unicast traffic storms.
- Control Plane Protection (CoPP): Protects the control plane from denial-of-service (DoS) attacks.
- 7. Network Management and Monitoring
- Telemetry: Real-time network telemetry for proactive monitoring and diagnostics.
- sFlow: Supported for traffic sampling and analysis.
- SNMP: Supports SNMPv1, v2, and v3 for remote monitoring.
- CLI and API: Provides a command-line interface (CLI) and supports automation with JSON-RPC, and REST APIs.
- Network Automation: Supports automation tools like Ansible, Puppet, Chef, and Python scripting.
- 8. Power and Cooling
