Cisco Catalyst 4500-E Series End-of-Life & EOSL Dates

PAST VENDOR SUPPORTCisco ended support between April 2018 and October 2025, depending on the part number.

The Catalyst 4500-E is a modular campus access chassis in four sizes from three to ten slots, with up to 48 Gbps per slot and room for 388 ports in one system. The seven- and ten-slot chassis run 1+1 redundant supervisors with sub-second failover, in-service software upgrades and 1+1 power redundancy, and line cards deliver PoE+ and UPOE from a budget of up to 1,500W per slot.

Supervisor engines from the 6-E to the 8-E define the system ceiling: the Supervisor 8-E reaches 928 Gbps and 250 Mpps with eight non-blocking 10G SFP+ uplinks, and terminates up to 20 Gbps of wireless traffic on the same UADP silicon as the fixed-configuration Catalysts. Line-card compatibility reaches back to the classic Catalyst 4500 series.

Modular Catalyst 4500-E chassis family. Cisco ended sales in 2020; hardware support runs to Oct 2025.

Every tracked Cisco Catalyst 4500-E Series SKU group is past Cisco end of service life (last group Oct 2025). 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: 16 successor part numbers.

Support Runway Score10/100 · Little or no runway
Why this score
  • Past end of service life: the first part numbers 103 months ago, the last 13 months ago
  • Vendor-published date, source-linked
  • Vendor-named replacement / migration path available
  • Category: modular distribution 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. Support ended between Apr 2018 and Oct 2025, depending on the part number. 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.

Past end of support and listed in the CISA Known Exploited Vulnerabilities catalog

1 catalogued vulnerability is associated with this product line, 1 of them linked to known ransomware campaigns. CISA lists these as actively exploited. This product is also past its last date of support, so the vendor no longer issues fixes for it. Past support on its own is a planning matter; both together is an audit finding, and for US federal agencies BOD 22-01 sets a remediation deadline.

Retired OS trains for this hardware

The software running on a device ages on its own clock. These Cisco OS trains tied to this product by Cisco's own bulletins have announced end-of-life dates — a unit capped on one of them can be unpatched even while the hardware is still supported.

Options from here

The Cisco Catalyst 4500-E 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. Current eBay listings for Catalyst 4500-E Series ↗

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.

Check your exact part numbers Weigh your support options

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.

Catalyst 4500-E Series questions

Is the Cisco Catalyst 4500-E Series end of life?

Yes. Every dated 4500-E Series SKU group is past its last date of support.

Where do these 4500-E Series dates come from?

Every end-of-sale and end-of-service-life date on this page links to the official Cisco EOL bulletin it was taken from.

What is the replacement for the 4500-E Series?

Cisco's end-of-life bulletin lists 16 successor part numbers as the recommended migration path for the 4500-E Series. Exact per-part-number replacements are in the linked bulletin.
