Technical Specifications

  • Product Line: Cisco Catalyst 9500X series (fixed 1RU/data-center core and aggregation switches; configurations include C9500X-28C8D and C9500X-60L4D)
  • Switching Capacity: Up to 12 Tbps per Cisco datasheet (some sources cite 12.8 Tbps full duplex, not confirmed for the 28C8D)
  • Forwarding Rate: Up to 8 Bpps
  • Ports (breakdown): C9500X-28C8D: 28x 100G QSFP28 + 8x 400G QSFP-DD. C9500X-60L4D: 60x 10/25/50G SFP56 + 4x 40/100/200/400G QSFP-DD
  • PoE Budget: None (non-PoE switch family; PoE not applicable)
  • Layer: L2/L3 (Layer 3 routing requires Network Advantage license)
  • 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
  • Est. Price: $50,000 - $110,000

Technical Specifications

  • 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
  • Est. Price: $1,783 - $4,604
