Cisco Catalyst 4500 Series End-of-Life & EOSL Dates
The Cisco Catalyst 4500 Series is a switch in Cisco's Catalyst product line. End-of-sale and end-of-service-life dates are listed by part number below, each linked to the Cisco EOL bulletin.
Every tracked Cisco Catalyst 4500 Series SKU group is past Cisco end of service life (last group Oct 2023). 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: 13 successor part numbers / 10 successor part numbers / WS-X45-SUP7-E / WS-X4624-SFP-E / 3 successor part numbers / 6 successor part numbers / 2 successor part numbers.

Support-lifecycle timing and source confidence only. Higher means more runway. It is not a risk, safety or compliance rating. How it is calculated
Past end of support and listed in the CISA Known Exploited Vulnerabilities catalog
1 catalogued vulnerability is associated with this product line, 1 of them linked to known ransomware campaigns. CISA lists these as actively exploited. This product is also past its last date of support, so the vendor no longer issues fixes for it. Past support on its own is a planning matter; both together is an audit finding, and for US federal agencies BOD 22-01 sets a remediation deadline.
CISA names product lines and software rather than part numbers, so each row states how it was matched. Confirm against the vendor advisory before acting: this augments vendor data, it does not replace it.

The Cisco Catalyst 4500 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. Current eBay listings for Catalyst 4500 Series ↗
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.
