Cisco Catalyst 3650 end of life: key dates
By Nico De Muynck · Updated July 25, 2026
Support ends soon, 98 days left.
The Cisco Catalyst 3650 reached, or reaches, its Last Date of Support (LDoS) on October 31, 2026. That is the hard stop: no TAC, no RMA, no software fixes after it.
Cisco Catalyst 3650 lifecycle milestones
These dates are from Cisco's official end-of-sale and end-of-life bulletin (EOL13617). They apply to the WS-C3650 and C3650 part numbers.
| Milestone | Date |
|---|---|
| End-of-Life announcement | 2020-10-31 |
| End of Sale | 2021-10-31 |
| Last ship date | 2022-01-30 |
| End of Software Maintenance | 2022-10-31 |
| End of Vulnerability and Security support | 2026-10-31 |
| Last Date of Support (LDoS) | 2026-10-31 |
What these dates mean
End of Sale is the last day the Catalyst 3650 could be ordered from Cisco. End of Software Maintenance is the last day it received bug-fix releases. Last Date of Support (LDoS) is the one that matters most: after it, there is no TAC support, no RMA replacement and no security fixes, so an unpatched switch on your network becomes a standing security and compliance risk. For the full milestone chain, see what Cisco LDoS means.
What replaces the Catalyst 3650?
Cisco positions the Cisco Catalyst 9300 Series as the successor. If you are still running Catalyst 3650 switches in production, budget the refresh now rather than discovering the gap during an audit or a failed RMA. New to the terminology? See EOL vs EOS vs EOSL.
