Cisco Catalyst 3560-X Series — End-of-Life & EOSL Dates
Standalone (non-stackable) sibling of the 3750-X. The switch hardware is past Cisco support as of Oct 2021.
Every tracked Cisco Catalyst 3560-X Series SKU group is past Cisco end of service life (last group Oct 2021). Units in production should be treated as unsupported. For past-EOSL units, weigh third-party maintenance, spares, replacement, or a documented run-to-failure. Cisco’s named migration path: WS-C3650-24TD-S.

Support-lifecycle timing and source confidence only. Higher means more runway. It is not a risk, safety or compliance rating. How it is calculated
Documented real-world exploitation of out-of-support units
Public security reporting documents active exploitation affecting this product line. It is summarised here because units past their last date of support no longer receive vendor fixes. This describes the published campaigns, not the state of any specific device.
Cisco Talos and the FBI reported (August 2025) that Static Tundra, a Russian state-sponsored group linked to FSB Center 16, is compromising unpatched and end-of-life Cisco IOS devices via the Smart Install feature (CVE-2018-0171) for long-term espionage. The Catalyst 3560-X is an IOS access-switch line with the Smart Install client feature; units past end of support no longer receive IOS security fixes, so Cisco's guidance for unpatched devices is to disable Smart Install.

Options from here
The Cisco Catalyst 3560-X Series is past Cisco end of service life. These are the paths teams take from here:
Keep it in production past the OEM cutoff with an independent maintainer.
Buy spares now, while units still circulate on the secondary market.
It is unsupported today. Set a migration timeline and budget.
Low-criticality role: document the risk, harden backups, retire on your terms.
Independent and informational. EOSL.ai sells no hardware and no maintenance, and lists no paid placements. Third-party maintenance keeps unsupported gear in production past the OEM cutoff; whether it fits depends on the role the asset plays.
