Ten Key Differences Between Cisco C9300L-24T-4G-A and C9300-24S-E

Cisco’s access layer switches, such as the C9300L-24T-4G-A (new-gen cloud core) and C9300-24S-E (classic enterprise model), cater to distinct network needs. Below is a detailed comparison across 11 dimensions:

1. Performance: Hardware Generations Dictate Capabilities

The C9300L-24T-4G-A, built on a new-generation ARM multi-core processor (2.5GHz dual-core), outperforms the classic MIPS-based C9300-24S-E (1.2GHz single-core) in key metrics:

• Forwarding Rate: 120Gbps (C9300L) vs. 80Gbps (C9300).

• RAM: 4GB DDR4 (expandable to 8GB) vs. 2GB DDR3 (max 4GB).

• Storage: 4GB eMMC (USB 3.0) vs. 2GB eMMC (USB 2.0).

2. Feature Set: Smart Automation vs. Basic Stability

Both support core IOS XE functions like VLANs, QoS, and 802.1X, but differ in advanced capabilities:

• C9300L-24T-4G-A: DNA Center 2.0 for automated configuration, traffic analytics, and predictive maintenance; 10G SFP+ uplinks for core integration.

• C9300-24S-E: Simplified Web GUI for small teams; legacy compatibility with older APs/IP phones.

3. Design & Build: New-Gen Craftsmanship

• C9300L-24T-4G-A: Metal-plastic hybrid casing (UL 94 V-0 fire rating), lighter weight (5kg), and honeycomb vents for better heat dissipation.

• C9300-24S-E: All-metal casing (6kg), traditional strip vents, and bulkier power adapter (45mm diameter).

4. User Experience: Ease of Management

• C9300L-24T-4G-A: Zero-touch deployment via DNA Center; real-time dashboard for traffic/alarms; remote firmware upgrades.

• C9300-24S-E: Manual configuration required; basic CLI/Web interface; on-site upgrades needed.

5. Cost-Effectiveness: Performance vs. Budget

• C9300L-24T-4G-A: Higher upfront cost (+30%) but lower long-term TCO (reduced IT labor, extended lifespan).

• C9300-24S-E: Lower initial price (-25%) but higher maintenance costs (manual management, shorter lifespan).

6. Use Cases & Advantages

• C9300L-24T-4G-A: Ideal for mid-to-large enterprises needing smart management, high scalability, and future-proofing (e.g., campus networks, branch offices).

• C9300-24S-E: Best for small businesses or legacy environments prioritizing stability and low cost (e.g., retail stores, clinics).

7. Firmware Upgrades: Pitfalls & Fixes

• Common Issues: Failed upgrades (due to power loss), incompatible SFP modules, or 802.1X authentication failures post-upgrade.

• Solutions: Use ROMmon to load old firmware; verify SFP compatibility; check Cisco’s hardware-software matrix before upgrading.

Conclusion

The C9300L-24T-4G-A and C9300-24S-E represent two generations of Cisco access switches. The former excels in performance and smart management for evolving networks, while the latter offers stability and affordability for traditional environments. Choose based on your network’s scale, complexity, and long-term goals.
