1. Architecture and Design
1.1. Cisco Catalyst 9300
- Stackable Design: The Catalyst 9300 features a stackable architecture that allows for stacking up to 8 switches, providing increased bandwidth and redundancy.
- High-Density Ports: The 9300 series supports a variety of interface options, including multi-gigabit Ethernet (up to 10 Gbps), catering to modern bandwidth demands.
1.2. Older Models (Catalyst 3850 and 2960-X)
- Stacking Capability: While the Catalyst 3850 also supports stacking, it is limited to 4 switches. The 2960-X series does not support stacking at all.
- Limited Bandwidth Options: The 3850 and 2960-X series primarily support Gigabit Ethernet ports, making them less suitable for high-bandwidth applications.
Table 1: Architecture Comparison
| Feature | Catalyst 9300 | Catalyst 3850 | Catalyst 2960-X |
| Stackable Design | Yes (up to 8 switches) | Yes (up to 4 switches) | No |
| High-Density Ports | Multi-Gigabit Ethernet (up to 10 Gbps) | Mostly Gigabit | Mostly Gigabit |
2. Power over Ethernet (PoE) Capabilities

| Feature | Catalyst 9300 | Catalyst 3850 | Catalyst 2960-X |
| Advanced Security | Yes (TrustSec and ETA) | Basic security features | Basic access control |
| Role-Based Access Control | Granular controls available | Limited role-based access | Basic access control |
4. Automation and Programmability
4.1. Cisco Catalyst 9300
- Built for Automation: The Catalyst 9300 supports automation features through Cisco DNA Center, enabling centralized management and orchestration of network resources.
4.2. Older Models (Catalyst 3850 and 2960-X)
- Limited Automation Features: While the Catalyst 3850 does support some automation features, it lacks the comprehensive capabilities and integration found in the 9300 series.
- Less Programmability: The 2960-X series offers minimal programmability, making it less suitable for environments that require automation.
Table 4: Automation and Programmability Comparison
| Feature | Catalyst 9300 | Catalyst 3850 | Catalyst 2960-X |
| Built for Automation | Yes (Cisco DNA Center integration) | Some automation features | Limited automation |
| Programmability | High (Open APIs and integration) | Moderate programmability | Minimal programmability |
5. Performance and Scalability
5.1. Cisco Catalyst 9300
- High Performance: With a switching capacity of up to 480 Gbps, the Catalyst 9300 is designed to handle high traffic loads, making it suitable for large enterprise networks.
- Scalability: Easily accommodates growing networks by stacking multiple switches.
5.2. Older Models (Catalyst 3850 and 2960-X)
- Performance Limitations: The Catalyst 3850 offers a maximum switching capacity of 440 Gbps, while the 2960-X has a lower capacity, making them less suitable for high-demand environments.
- Scalability Constraints: The stacking capabilities of the 3850 are limited compared to the 9300, affecting scalability.
Table 5: Performance and Scalability Comparison
| Feature | Catalyst 9300 | Catalyst 3850 | Catalyst 2960-X |
| Switching Capacity | Up to 480 Gbps | Up to 440 Gbps | Lower capacity |
| Scalability | Supports stacking of up to 8 switches | Supports stacking of up to 4 switches | No stacking capability |
