Options from here
The Cisco Catalyst C4500E 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.
