Cisco Catalyst 4948 Series — End-of-Life & EOSL Dates

PAST VENDOR SUPPORTCisco ended support in July 2018.

The Cisco Catalyst 4948 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 4948 Series SKU group is past Cisco end of service life (last group Jul 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: Cisco Catalyst 4948E / 4948E-F.

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 4948 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.

Options from here

The Cisco Catalyst 4948 Series is past Cisco end of service life. These are the paths teams take from here:

Third-party maintenance

Keep it in production past the OEM cutoff with an independent maintainer.

Pre-stock spares

Buy spares now, while units still circulate on the secondary market.

Plan replacement

It is unsupported today. Set a migration timeline and budget.

Run to failure

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.
