Past end of serviceEvery 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.

EOSL — PAST1 SKU in this group
Options from here
Unsupported nowThe Cisco Catalyst 4948 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 or maintenance and lists no paid placements. Third-party maintenance keeps unsupported gear in production past the OEM cutoff; whether it fits depends on the asset's role.
