• Tier-Restricted Advanced Security Functions:
  Encrypted Traffic Analytics (ETA), Adaptive Policy group-based microsegmentation, full IPFIX streaming telemetry and expanded OSPF route scale require a Meraki Advanced subscription license; only baseline threat prevention is available under Meraki Enterprise tier

7. Layer 2 & Layer 3 Protocol Support

Full Layer 2 Feature Set

Layer 3 Routing Protocols

• Limitation: Advanced routing protocols including BGP and full Policy-Based Routing (PBR) are unlocked exclusively with the Meraki Advanced subscription license

8. Software & Meraki Cloud Licensing Ecosystem

• Operating System: Custom hybrid Cisco IOS XE image optimized exclusively for Meraki Dashboard cloud orchestration
• Core Licensing Difference vs C9300L-24T-4X-E / C9300L-24T-4X-A: No perpetual Cisco DNA Network Essentials / Network Advantage licenses. The switch requires mandatory time-based Meraki term subscriptions (1/3/5/7/10-year) in two tiers:
