Cisco Catalyst 3750G Series End-of-Life & EOSL Dates

PAST VENDOR SUPPORTCisco ended support in January 2018.

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 Jan 2018). 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.

  • Vendor-published date, source-linked
  • Vendor-named replacement / migration path available
  • Category: switch

Support-lifecycle timing and source confidence only. Higher means more runway. It is not a risk, safety or compliance rating. How it is calculated

Figure 1. Cisco issues no software maintenance and no security fixes for this product. Third-party maintenance, spares or replacement are the paths from here. EOSL.ai sells none of them and takes no placement fee.
Figure 2. The 3750G Series against 7 other models in Cisco Catalyst. Each bar runs from the earliest milestone Cisco publishes for that model, which is first availability where it gives one and end of sale otherwise, to its last date of support. The vertical rule is today; bars entirely to its left are past support. 12 further models in this line publish no usable date range and are not plotted.
