Questions & Answers

What is the Cisco Catalyst 9500X?

The Catalyst 9500X is the next-generation tier of the 9500 family built on Cisco Silicon One ASICs, delivering high-density 100G and 400G switching for large campus cores and aggregation.

What is the difference between the Catalyst 9500 and 9500X?

The 9500X moves from UADP to Cisco Silicon One (Q200), adding 400G uplink capability, dramatically higher throughput, larger tables, and line-rate encryption that standard 9500 models cannot match.

What ports does the Catalyst 9500X-28C8D offer?

The flagship C9500X-28C8D provides 28x100G QSFP28 ports plus 8x400G QSFP-DD ports in a single rack unit, delivering up to 8 Tbps of switching capacity.

Does the Catalyst 9500X support 400G?

Yes. QSFP-DD 400G ports enable ultra-high-bandwidth core links and future-proof capacity for AI, video, and data-heavy campus backbones.

Does the 9500X support line-rate encryption?

Yes. Silicon One enables WAN-MACsec and IPsec at line rate across ports, securing high-speed interconnects without dedicated encryption appliances.

Where is the Catalyst 9500X best deployed?

Large campus cores, collapsed core and aggregation in bandwidth-heavy environments, SD-Access fabric borders, and sites consolidating multiple 100G domains.

Does the Catalyst 9500X support StackWise Virtual?

Support depends on software release and model. Recent IOS XE versions add StackWise Virtual on 9500X platforms, so verify your target release before design.

What licensing does the Catalyst 9500X use?

Like the broader Catalyst 9000 family, it pairs Network Essentials or Advantage with Cisco DNA Essentials or Advantage subscriptions, with Advantage recommended for core deployments.
