Lifecycle · EoL & refresh planning
Check End-of-Sale (EoS), End-of-Software-Maintenance (EoSM), and Last-Day-of-Support (LDoS) for Cisco routers, switches, IP phones, ISRs, ASAs, and voice gear. Get a clean replacement recommendation you can show to your CFO.
Running gear past EoSM means no new software, no security fixes, and no TAC help when something breaks. This tool takes a model number and gives you the dates that matter plus the Cisco-endorsed successor. Dates here are a curated snapshot — always confirm against Cisco's official EoL bulletin before making a purchase decision.
EoS is when you can't buy it new from Cisco anymore. EoSM is when Cisco stops publishing software/security fixes. LDoS is when TAC closes the book. For most audit and compliance frameworks (PCI, HIPAA, SOC 2, CMMC), running past EoSM is a finding — plan replacement 6-12 months ahead.
The cheapest path is never to be caught by surprise. Export your device inventory once a quarter (show version on IOS, utils system uptime on CUCM), match against Cisco's EoL bulletin, and flag anything within 18 months of EoSM.
Cisco gives a grace period (usually 3 years) where TAC will still answer, but no new software is released. Good for planning, bad for long-term security posture.
Yes — past LDoS, licenses still work but are no longer transferable to replacement hardware under most programs. Cisco will rarely budge on this.
EoS announced, replacement: Catalyst 8200L-1N-4T. Same footprint, faster CPU, IOS-XE 17.x LTS.
EoS announced. Replacement: Cisco 8841 is being replaced by the 9800 series desk phones and Webex Desk series, depending on your calling platform.
