Stacking support: Not confirmed in research; Catalyst 9500 family supports StackWise Virtual, verify for 9500X
Packet Buffer: 80 MB dedicated low-latency buffer; up to 8 GB HBM deep buffer
ASIC: Cisco Silicon One Q200
Power Supplies: 2 power supply slots (per Cisco product overview)
Curation Review
✔ Pros:High-density 100G/400G and 10/25/50G connectivity for data center core, aggregation, and spine roles; Up to 8 Bpps forwarding rate with a Silicon One Q200 ASIC; Large buffering (80 MB dedicated plus up to 8 GB HBM) suited to deep-buffer and bursty traffic; Cisco DNA licensing and automation (DNA Essentials/Advantage) with Layer 3 routing support; Strong platform longevity and wide partner/support availability
✘ Cons:Very high acquisition cost compared with general-purpose data center or campus switches; No PoE, so it is unsuitable for powering access endpoints; Port options are fixed per model, so flexibility is limited versus modular Catalyst 9600X; Advanced features and Layer 3 require higher-tier licensing that adds recurring cost; Published switching capacity differs between sources (12 vs 12.8 Tbps), so buyers must verify against the current Cisco datasheet
Stacking support: Not confirmed; no physical stacking documented in sources reviewed

Curation Review
✔ Pros:Layer 3 switching in a 24-port 1U chassis; 8x 2.5GbE PoE++ ports for multi-gig wireless and workstation uplinks; 400W total PoE budget with up to 60W per port; 2x 10G SFP+ uplinks; 112 Gbps switching capacity and 56 Gbps non-blocking throughput; managed centrally through UniFi Network; list price of $799 USD from Ubiquiti's US store is competitive for L3 PoE++ hardware
✘ Cons:400W total PoE budget is limited if many high-power PoE++ devices are connected at once; No physical stacking documented, so scaling beyond one unit needs separate management; Port breakdown is described inconsistently across retailer listings, so the official Ubiquiti datasheet should be checked; Reseller prices vary widely (about $799 to $951 USD, plus higher regional prices); Independent hands-on reviews with measured performance were not found; Requires UniFi Network 8.0.24 or later for management
