Switching Capacity: 56 Gbps (24P-4G) to 128 Gbps (24-port 4x10G) and 104 Gbps (48P-4G) to 176 Gbps (48P-4X); varies by SKU and source
Forwarding Rate: 83.33 Mpps (24P-4G) to 190.4 Mpps (24P-4X); 154.76 Mpps (48P-4G) to 261.9 Mpps (48P-4X); varies by SKU and source
Ports (breakdown): 24 or 48 x 10/100/1000 downlink ports (PoE+ on P models, non-PoE on T models; some 48-port PXG variants add mGig ports) plus 4 fixed uplinks: 4 x 1G SFP (-4G) or 4 x 10G SFP+ (-4X)
PoE Budget: 24P models: about 370 W default, up to about 740 W with redundant PSU; 48P models: about 740 W default, up to about 1440 W with two PSUs (sources conflict, e.g. 600 W and 1 kW PSU options quoted)
Layer: L2/L3: Network Essentials provides L2 switching with basic L3 features; Network Advantage adds full dynamic L3 routing
Stacking support: Yes, StackWise-80 with 80 Gbps stacking bandwidth, up to 8 switches (requires stacking module/kit)
Curation Review
✔ Pros:Cisco StackWise-80 stacking of up to 8 units with 80 Gbps stacking bandwidth; 4x10G SFP+ uplink option for higher-bandwidth aggregation; Full PoE+ (802.3at) on P models with budgets up to roughly 1440 W with redundant power; Two licensing tiers (Network Essentials and Network Advantage) let buyers pay only for needed L3 features; Lower price point than Catalyst 9300 for standard campus access deployments
✘ Cons:Uplinks are fixed with no modular expansion slots, which limits future upgrade paths; Full dynamic L3 routing requires the more expensive Network Advantage license; Stacking needs a separate stacking module and is capped at 8 units; Switching capacity and PoE budgets differ widely between SKUs, making spec comparison and sizing confusing; Lower forwarding performance and feature depth than Catalyst 9300 for aggregation or core roles

Curation Review
✔ Pros:Full 720W PoE budget with 64W PoE++ on 16 of the 48 copper ports, suited to high-power devices; 16 multi-gigabit 2.5GbE ports for Wi-Fi 6/7 access points and high-speed endpoints; Layer 3 routing (inter-VLAN, static routes, DHCP relay) without a separate router; 4x 10G SFP+ uplinks for aggregation or fibre; 224 Gbps switching capacity and 167 Mpps forwarding rate; centralized management through UniFi Network with a touchscreen display; rack-mountable 1U form factor with redundant DC power input
✘ Cons:High price relative to smaller UniFi switches, with US prices roughly $1,300 to $1,500 at major sellers; requires UniFi Network 8.0.24 or later, so it is tied to the UniFi ecosystem; 720W total PoE budget can be exhausted if all 48 ports draw high power, so per-port budgeting is needed; 6.2 kg weight and full-depth chassis require a sturdy rack; stacking support is not listed in official specifications, which limits scaling as a single logical unit; fan noise is not specified, which matters for non-data-centre installs
