Cisco Catalyst 3850 End of Support: What Does It Mean for Consumers?

I understand the importance of staying up-to-date with the latest technology trends and developments. One such development that has caught my attention is the impending end of support for the Cisco Catalyst 3850 series, which is set to occur in October 2025. In this blog post, we will explore what this means for consumers and discuss whether they will continue to use the Catalyst 3850 or consider moving to refurbished Cisco 2960X and 2960XR switches, which will still be supported by Cisco.

Understanding End of Support (EoS) and End of Life (EoL)

Before we delve into the implications of the Catalyst 3850 reaching its end of support (EoS), let's clarify what EoS and end of life (EoL) mean in the context of networking equipment.

EoS refers to the date when a product is no longer supported by the manufacturer. This means that Cisco will no longer provide software updates, bug fixes, or security patches for the Catalyst 3850 after October 2025. On the other hand, EoL signifies the end of the product's life cycle, indicating that it will no longer be manufactured or sold by Cisco.

The Impact of EoS on Consumers

With the Catalyst 3850 reaching its EoS, consumers who currently use this switch will need to evaluate their options moving forward. While the switch will continue to function, the lack of ongoing support may pose potential risks and limitations.

One of the main concerns is security. Without regular software updates and security patches, the Catalyst 3850 may become more vulnerable to cyber threats. As new vulnerabilities are discovered, hackers may exploit them, potentially compromising the network's integrity.

Additionally, as technology advances, new features and functionalities are introduced. Without ongoing support, consumers will miss out on these advancements, which could impact their ability to keep up with evolving business needs and industry standards.

Securing Cisco Catalyst 3850 Beyond End-of-Support: Mitigation Techniques

As technology evolves, so do the challenges in maintaining the security of networking equipment, especially when faced with end-of-support (EOS) scenarios. We will explore effective mitigation techniques to secure Cisco Catalyst 3850 switches when reaching EOS. By implementing these strategies, you can fortify your network infrastructure and ensure continued protection against potential vulnerabilities.

Air Gap the Switch Management VLAN:

One robust approach to enhance security is to air gap the switch management VLAN. By restricting access to the management interface solely through a console cable, you create an additional layer of defense against unauthorized remote access. This physical isolation minimizes the attack surface and provides a secure means of managing the switch.

Firewall Protection for Switch Management VLAN:

Place the switch management VLAN behind a firewall to control and monitor incoming and outgoing traffic effectively. Configure firewall rules to permit access only to authorized users and devices. This ensures that any attempts to access the management VLAN are scrutinized and restricted based on predefined security policies.

Implement Two-Factor Authentication (2FA):

Strengthen access controls by implementing 2FA for switch management VLAN. Solutions like Fortigate user-based firewall rules coupled with 2FA authentication enhance the authentication process, requiring users to provide two forms of identification before gaining access.

Strengthening your network security in the face of EOS challenges is crucial, and these strategies can be pivotal in maintaining a resilient infrastructure.

As the Cisco Catalyst 3850 approaches its end-of-support, proactively implementing these mitigation techniques is vital for safeguarding your network. By combining physical isolation, firewall protection, and advanced authentication methods, you can mitigate potential risks and ensure a robust defense against evolving cybersecurity

Considering Refurbished Cisco 2960X and 2960XR Switches

Given the EoS status of the Catalyst 3850, consumers may consider alternative options to ensure continued support and access to the latest features. One such option is to explore refurbished Cisco 2960X and 2960XR switches, which will still be supported by Cisco.

Refurbished switches offer a cost-effective solution for consumers who wish to upgrade their networking equipment without investing in brand new devices. These switches undergo a rigorous refurbishment process to ensure they meet Cisco's quality standards and are backed by a warranty.

The Cisco 2960X and 2960XR switches offer comparable performance to the Catalyst 3850 and provide a smooth transition for consumers. With ongoing support from Cisco, consumers can continue to receive software updates, bug fixes, and security patches, ensuring the longevity and security of their network infrastructure.

Weighing the Pros and Cons

When deciding whether to stick with the Catalyst 3850 or switch to refurbished Cisco 2960X and 2960XR switches, consumers should consider the following pros and cons:

Pros of Sticking with Catalyst 3850:

• Familiarity with the product

• No immediate need for advanced features

• No budget constraints

Cons of Sticking with Catalyst 3850:

• Lack of ongoing support and security updates

• Potential compatibility issues with newer technologies

• Missed opportunities for new features and functionalities

Pros of Switching to Refurbished Cisco 2960X and 2960XR Switches:

• Ongoing support, software updates, and security patches

• Access to new features and functionalities

• Cost-effective solution

Cons of Switching to Refurbished Cisco 2960X and 2960XR Switches:

• Adjustment period to a new product

• Potential compatibility issues with existing infrastructure

• Dependency on third-party vendors for refurbished devices

Conclusion

The end of support for the Cisco Catalyst 3850 series in October 2025 poses a significant decision for consumers. While some may choose to continue using the Catalyst 3850 despite its EoS status, others may opt to switch to refurbished Cisco 2960X and 2960XR switches, which will still be supported by Cisco.

Ultimately, the decision will depend on individual circumstances, including budget constraints, desired features, and the importance of ongoing support and security updates. It is advisable for consumers to carefully evaluate their options and consult with networking professionals to make an informed decision that aligns with their business needs and goals.
