Cisco Catalyst 9500 vs 9600
The Catalyst 9500 is a fixed-configuration core switch, while the Catalyst 9600 is a modular chassis core switch with redundant supervisors. Choose the 9500 for a compact, high-throughput core; choose the 9600 for a resilient, future-proof campus core that scales by adding line cards.
Cisco Catalyst 9500
Fixed 1RU/2RU core and aggregation switch with up to 6.4 Tbps capacity.
- Up to 6.4 Tbps switching capacity, up to 2 Bpps
- Native 10G/25G/40G/100G interfaces
- StackWise Virtual for two-node redundancy
- Compact fixed form factor, lower entry cost
Cisco Catalyst 9600
Modular chassis core switch with redundant supervisors and line cards.
- Sup-1: 9.6 Tbps full-duplex, up to 3 Bpps
- Dual supervisor for in-service redundancy
- Up to 2.4 Tbps per slot with Sup-1
- Scales by adding 10/25/40/100G line cards
Cisco Catalyst 9500 vs Cisco Catalyst 9600: spec comparison
| Spec | Cisco Catalyst 9500 | Cisco Catalyst 9600 |
|---|---|---|
| Architecture | Fixed configuration | Modular chassis |
| Switching capacity | Up to 6.4 Tbps | 9.6 Tbps full-duplex (Sup-1) |
| Forwarding performance | Up to 2 Bpps | Up to 3 Bpps (Sup-1) |
| Per-slot bandwidth | N/A (fixed) | Up to 2.4 Tbps per slot |
| Supervisor redundancy | StackWise Virtual (2 nodes) | Dual supervisor (in-service) |
| Interfaces | 10G/25G/40G/100G fixed | 10G/25G/40G/100G line cards |
| Scaling model | Add fixed units | Add line cards |
| ASIC | UADP (high-performance) | UADP 3.0 (Sup-1) |
| Software | Cisco IOS XE | Cisco IOS XE |
| Typical use | Compact campus core | Large resilient campus core |
| Warranty | Enhanced Limited Lifetime | Enhanced Limited Lifetime |
Choose Cisco Catalyst 9500 if
Choose the Catalyst 9500 for a compact, cost-effective core or aggregation layer where a fixed switch (optionally paired with StackWise Virtual) delivers enough capacity and redundancy.
Choose Cisco Catalyst 9600 if
Choose the Catalyst 9600 for a large campus core that needs chassis-level resilience, dual supervisors, in-service upgrades, and the ability to scale by adding line cards over time.
Verdict
Both are UADP-based IOS XE core switches; the decision is fixed versus modular. The 9500 is the right call for a compact, high-throughput core at a lower entry cost. The 9600 is the choice when you want maximum resilience, dual supervisors, and a chassis you can grow with line cards for years. For mission-critical cores, the 9600's redundancy usually justifies the premium.
Frequently asked questions
What is the main difference between Catalyst 9500 and 9600?
The 9500 is a fixed-configuration core switch, while the 9600 is a modular chassis with redundant supervisors and swappable line cards. The 9600 scales higher and is more resilient; the 9500 is more compact and lower cost.
Which has more switching capacity?
The 9600. With Sup-1 it delivers 9.6 Tbps full-duplex and up to 3 Bpps, versus up to 6.4 Tbps and 2 Bpps on the 9500.
Does the Catalyst 9500 support redundant supervisors?
Not in a single chassis, since it is fixed-configuration. It achieves redundancy through StackWise Virtual across two units. The 9600 supports dual supervisors within one chassis.
Is the 9600 worth it over the 9500?
For large or mission-critical cores that need in-service upgrades, dual supervisors, and line-card growth, yes. For a compact core with predictable capacity, the 9500 is the more economical fit.
