The Cisco Catalyst 3750G- 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 3750G- Series SKU group is past Cisco end of service life (last group Mar 2014). 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-C3750G-24TS-E1U.

Options from here
The Cisco Catalyst 3750G- 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.
