Little or no runway
Support Runway Score

Every tracked Cisco Catalyst 4500 Series SKU group is past Cisco end of service life (last group Oct 2023). 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: C1-X45-SUP8L-E / WS-X45-SUP7L-E / WS-X45-SUP7-E / WS-X4624-SFP-E / WS-X4148-FX-MT / WS-X45-SUP6L-E / WS-C4503-E.

Why this score
  • Past end of service life — 133 months ago
  • Vendor-published date, source-linked
  • Vendor-named replacement / migration path available
  • Category: switch

The score reflects support-lifecycle timing and source confidence only — higher means more support runway. It is not a risk, safety or compliance rating. How it’s calculated →

Options from here

Unsupported now

The Cisco Catalyst 4500 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 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.
