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 multi-gig access layer: 16 x 2.5GbE ports plus 4 x 10G SFP+ uplinks; Layer 3 features including static routing, inter-VLAN routing, ACLs and DHCP relay; 720W PoE budget with PoE++ (64W) on 16 ports; Non-blocking 224 Gbps switching capacity and 167 Mpps forwarding rate on the official spec sheet; Managed through UniFi Network with a 1U rack-mount form factor
✘ Cons:720W PoE budget cannot power all 48 ports at PoE++ levels, so PoE planning is required for high-draw devices; No stacking support listed on the official spec sheet; 4 SFP+ uplinks are the only 10G connectivity, with no 25G or 100G options; Official and retailer listings disagree on the PoE+/PoE++ port split, so the exact layout should be verified before purchase; Street price ranges widely across retailers (about $1,299 to $1,599), and some listings show stock delays of 5 to 14 days
