Key Differences vs C9500-48Y4C-A (Network Advantage)

• C9500-48Y4C-M: Network Meraki license with native Meraki cloud dashboard management, all full Layer3/security features identical to Network Advantage, plus unified Meraki hybrid cloud visibility
• C9500-48Y4C-A: Network Advantage license, on-prem DNA Center primary management, no native Meraki cloud integration

Typical Deployment Scenarios

• Hybrid Meraki + Catalyst unified campus aggregation layers
• Medium enterprise data center leaf-spine fabric with high-density 25G server downlinks and 100G spine uplinks
• Multi-campus inter-building fiber backbone core with centralized Meraki cloud monitoring
• SD-Access fabric border or intermediate aggregation nodes requiring single-pane Meraki cloud visibility
• Enterprise networks mixing Meraki wireless, security appliances and Catalyst core switches
