Upgraded access switches like Cisco Catalyst 9300L and UniFi ECS series offer high throughput, advanced PoE support, and robust Layer 3 features, with differences in port density, power efficiency, and scalability.

Cisco Catalyst 9300L Series

Models Compared: C9300L-48P-4G-A (48-port Gigabit PoE+) vs. C9300L-24P-4X-E (24-port Gigabit PoE++) Performance:

• Forwarding Rate: 48-port model achieves 158Mpps vs. 132Mpps for the 24-port model, making it better for high-traffic environments like large meeting rooms or warehouses .
• Memory & Storage: 48-port has 4GB DDR4 RAM + 16GB eMMC flash; 24-port has 2GB RAM + 8GB flash, allowing the 48-port to handle advanced features and maintain longer log retention .
• Power Consumption: 48-port consumes ~65W under full load; 24-port ~45W, with smart power adjustment to optimize energy use .
• PoE Support: 48-port supports PoE+ (30W) for standard devices; 24-port supports PoE++ (90W) for high-power devices like 4K cameras .
• Layer 3 Features: 48-port supports IPv6 routing natively; 24-port requires additional licensing . Use Case: Ideal for high-density enterprise environments requiring scalability, advanced routing, and robust PoE support.

UniFi ECS Series

Performance & Features:

• Port Speeds: 1/2.5/10G downlinks, with 10/25/100G uplinks for backbone connectivity .
• Redundancy: Multi-Chassis Link Aggregation (MC-LAG) for seamless failover and load balancing .
• Layer 3 Routing: Hardware-accelerated inter-VLAN routing, often replacing external routers .
• PoE & Management: Centralized VLAN, PoE, and link aggregation management; color-coded LEDs simplify troubleshooting .
• Use Case: Suitable for enterprise campuses, AV over IP deployments, and high-performance Wi-Fi 7 networks requiring low latency and high throughput .
