What does last day of support (LDOS) mean for your Cisco products, and how does that date compare to the end of sale (EOS) date? Understanding Cisco’s milestones starts with the end of life (EOL) process. EOL “consists of a series of technical and business milestones and activities that, once completed, make a product obsolete,” per Cisco’s EOL policy. “Once obsolete, the product is not sold, improved, maintained, or supported.”

End of sale

The EOS date indicates the last day you can purchase a specific product. Though Cisco may stop selling the product, they will typically continue support for four or five years after the EOS date. But there will be looming milestones to be aware of, such as reaching a point when software features are no longer added and then another date when Cisco stops implementing vulnerability fixes.

Last day of support

When a product reaches its LDOS date, Cisco no longer offers any software updates, support, or security patches for that specific model. This could expose your network to vulnerabilities, compatibility issues, and potential disruptions to your business operations. Therefore, staying informed and preparing for these EOL milestones is critical. Keep time on your side by planning your Cisco upgrades, renewals, and purchases well in advance.

You may be wondering: With varying support dates and milestones for different products across your vast network, how can you maintain visibility and manage everything with time to spare?
