End of Life vs End of Support: What’s the Difference in Cisco?
What is End of Life (EOL)?
When Cisco announces a product as End of Life, it signals that the product will no longer be developed or sold. However, the EOL phase doesn't immediately mean the product stops functioning. Instead, it kicks off a timeline of phase-outs, which includes the following key stages:
End of Sale Announcement: Cisco issues a formal notice that the product will no longer be available for purchase after a specific date.
Last Ship Date: After the sale announcement, Cisco allows a buffer period during which customers can still purchase the product, but this buffer ends with the last ship date. This is the last day Cisco will fulfill orders for that product.
End of Software Maintenance: Cisco will cease releasing any software updates or patches for the product after this point. However, depending on the service contracts, critical bug fixes and security patches might still be provided for a limited time.
End of Support (EOS): This is the final phase, marking the end of both hardware and software support. Once a product reaches this stage, Cisco will no longer provide technical support, updates, or hardware repairs.
At the heart of this process is the goal of transitioning customers away from aging technology and onto newer, more secure, and efficient systems. Cisco products are known for their long lifecycle, but even they must eventually be retired.
What is End of Support (EOS)?
While End of Life is a broad term indicating the phase-out of a product, End of Support (EOS) is the specific point at which a product stops receiving any technical assistance from Cisco. For organizations, this means:
No more security updates: Vulnerabilities discovered in the product after this point will not be patched, leaving the system potentially exposed to cyber threats.
No bug fixes: If a critical bug is found, Cisco will not provide any patches or workarounds.
No technical support: If issues arise with the product, contacting Cisco will no longer yield assistance. Organizations will be left to troubleshoot or rely on third-party support.
No hardware replacements: Should a piece of hardware fail, Cisco will no longer offer replacement parts or repairs.
Why Is This Important?
For many companies, operating on hardware or software that has reached EOS can lead to significant risks. The lack of support can make the business vulnerable to security breaches, especially as cyber threats evolve. Moreover, using outdated equipment or software could lead to compliance issues, especially in industries where data protection is critical (e.g., healthcare, finance).
How Are EOL and EOS Related?
End of Life is a broader term, which eventually leads to End of Support. The EOL announcement gives organizations time to prepare for the EOS. Businesses typically receive a timeline from Cisco, detailing the expected last ship date, end of software maintenance, and EOS.
For example, Cisco may announce that a router will enter its EOL phase, with the EOS expected to occur in 5 years. This means that customers have time to purchase the router, continue receiving updates and bug fixes, but must begin planning for its eventual decommissioning before the EOS date.
Cisco's Product Lifecycle: A Real-World Example
Consider the Cisco Catalyst 2960 series, a popular line of switches for businesses. In 2019, Cisco announced the End of Life for the 2960 series, with the End of Support scheduled for October 2024. Customers were given time to purchase last-minute units, receive necessary software updates, and prepare for the EOS in 2024.
For a business still running the 2960 series after 2024, the lack of support could lead to operational risks. With no security updates, the switches may become vulnerable to exploits. Moreover, if a switch fails, replacement parts will no longer be available from Cisco, potentially causing extended downtime while a replacement is found.
Implications of Running Unsupported Products
Running a product after the EOS date introduces significant risks. Not only is the system vulnerable to security breaches, but the lack of software updates can lead to compatibility issues with newer applications or infrastructure. Furthermore, regulatory bodies may penalize companies that run unsupported technology in sensitive environments, such as healthcare or financial services, where compliance with standards like HIPAA or PCI-DSS is mandatory.
Strategies for Managing EOL and EOS Transitions
Proactive Monitoring: Organizations should track the lifecycle of their Cisco products. Cisco provides a Product Lifecycle Management (PLM) tool, allowing companies to monitor important milestones, such as EOL announcements and EOS dates.
Extended Support Contracts: Cisco offers Smart Net Total Care (SNTC) and other extended support contracts that may provide some post-EOS support, including hardware replacements and security patches. This is often a temporary solution to give organizations more time to migrate.
Third-Party Support: For some businesses, transitioning away from a product by the EOS date may not be feasible. In such cases, third-party vendors often provide extended hardware and software support for EOL/EOS products. While not as comprehensive as Cisco’s support, it can be a valuable stopgap measure.
Upgrade and Replacement: Ideally, businesses should plan their technology refresh cycles well before a product reaches its EOS. Cisco regularly releases new products with enhanced features and better security, making it crucial to stay up to date with Cisco’s product announcements.
Conclusion: Don’t Get Caught Off-Guard
The terms End of Life and End of Support might sound similar, but they have very different implications for businesses using Cisco technology. Knowing the difference allows organizations to plan for technology refreshes, avoid unplanned downtime, and protect themselves from security vulnerabilities. By understanding and preparing for these lifecycle stages, businesses can avoid the risks of running unsupported products while maximizing their investment in Cisco solutions.
