Description

Executive Summary

The Cisco Catalyst C8300-1N1S-4T2X is a modular edge router built for large enterprise branch offices and regional headquarters. Its key differentiator is its flexible port configuration, which includes a high-speed 25GbE interface and a combination of 1GbE and 10GbE ports, making it suitable for aggregating diverse types of network links.

Decoding the Model Number: C8300-1N1S-4T2X

The suffix breaks down its fixed interface configuration:

• -1N: 1 x 1/10 Gigabit Ethernet Network Interface (SFP+)

• -1S: 1 x 1/10/25 Gigabit Ethernet Speed Interface (SFP28) – This is a key high-speed port.

• -4T: 4 x 1 Gigabit Ethernet Twisted-pair (RJ-45) Ports

• -2X: 2 x 10 Gigabit Ethernet X2 / SFP+ Interfaces (This is a less common designation, but logically points to two additional 10GbE SFP+ ports).

This combination provides excellent flexibility for connecting to various WAN services and high-speed LANs.

Key Highlights & Features

• High-Speed Connectivity Ready: The inclusion of a 25GbE SFP28 port future-proofs the router for high-bandwidth applications like data center interconnects or high-capacity internet links.

• Port Diversity: Offers a balanced mix of 1GbE RJ-45 ports for standard office connections and multiple 10GbE/25GbE SFP+ ports for fiber-based WAN/LAN uplinks.

• SD-WAN Powerhouse: As part of the Catalyst 8300 series, it is engineered to deliver top-tier performance for Cisco SD-WAN, providing application optimization, security, and intelligent path selection across hybrid WANs.

• Modular Expansion: Features service module slots for adding specialized interfaces like additional 40GbE ports, 5G/LTE modems for wireless WAN failover, or legacy T1/E1 serial connections.

Detailed Specifications Breakdown

Who Is This Router For?

• Large Enterprise Branches with Diverse Needs: Ideal for sites that require a mix of standard 1GbE connections for local devices and high-speed 10GbE/25GbE links for uplinks to the data center or internet.

• Organizations Future-Proofing Their WAN: The 25GbE port provides a clear upgrade path for bandwidth-intensive future applications.

• SD-WAN Deployments Requiring High Density: The multiple high-speed ports are perfect for connecting to multiple ISPs or MPLS providers simultaneously for SD-WAN redundancy and load balancing.

Important Considerations / Limitations

• Enterprise-Grade Cost and Complexity: This is a high-end router with a corresponding price tag. It requires skilled network engineers for configuration and management.

• Software Licensing: Full functionality, especially for SD-WAN and security features, requires Cisco DNA Essentials or Advantage licenses, which are subscription-based.

• Physical Size: As a 2RU device, it requires adequate rack space.

Comparison Context: C8300-1N1S-4T2X vs. Other Models

Verdict

The Cisco Catalyst C8300-1N1S-4T2X is a highly flexible and powerful edge router tailored for modern, bandwidth-intensive enterprise WANs. Its standout feature is the blend of a future-ready 25GbE port with a high density of 10GbE and 1GbE ports, making it an excellent choice for large branches that need to aggregate various types of connections while preparing for future bandwidth growth within an SD-WAN architecture.
