Cisco Catalyst 3750G Series Replacement: What Cisco Recommends
Cisco support for the Cisco Catalyst 3750G Series has ended for some part numbers (last group runs to Jan 2018). Unsupported units need a plan. Cisco's own end-of-life bulletin names the successor below, quoted from the source, with the successor's live support status where EOSL.ai tracks it.

Do I have to buy the Cisco-recommended replacement?
No. The bulletin's named successor is Cisco's suggested path, not an obligation.
