Questions & Answers

What is the Cisco Catalyst 9500 Series?

The Catalyst 9500 is Cisco's fixed-configuration core and aggregation switch family for enterprise campus networks, offering wire-speed 10G, 25G, 40G, and 100G platforms built on UADP ASICs.

Where does the Catalyst 9500 fit in a network design?

It is designed for the campus core and distribution or aggregation layers, collapsing layers in mid-size networks or anchoring SD-Access fabrics as border and control-plane nodes.

What models are in the Catalyst 9500 family?

Key models include the C9500-16X and C9500-40X (10G), C9500-24Y4C (25G), C9500-12Q and 24Q (40G), and C9500-32C, 32QC, and 48Y4C (100G and 25G high-performance).

Does the Catalyst 9500 support StackWise Virtual?

Yes. StackWise Virtual joins two 9500s into one logical switch across fiber links, providing chassis-level redundancy with single-point management as a modern VSS replacement.

What is the difference between the 9500 and 9500 high-performance models?

High-performance models (32C, 32QC, 48Y4C, 24Y4C) use the UADP 3.0 ASIC with higher throughput, deeper buffers, and greater table scale than standard UADP 2.0 models.

What licensing does the Catalyst 9500 use?

The 9500 combines Network Essentials or Advantage with Cisco DNA Essentials or Advantage subscriptions. DNA Advantage unlocks SD-Access, advanced telemetry, and automation.

Are Catalyst 9500 power supplies and fans redundant?

Yes. The 9500 supports dual hot-swappable power supplies and redundant fans with selectable airflow SKUs for proper hot aisle and cold aisle alignment.

Did the Catalyst 9500 replace the Catalyst 4500-X and 6800?

Yes. The 9500 Series is Cisco's migration path from the Catalyst 4500-X, 6840-X, and 6880-X platforms, delivering higher performance with modern IOS XE software.
